Covid's making it difficult for people's immune systems to suppress cancer. There was a recent small-scale mouse study showing "tumor shrinkage" in a small percentage of those transgenic mice. This is a much larger analysis of the oncogenic potential of covid in humans. Guess which story the news has been reporting.

Abstract The 2019 outbreak of SARS-CoV-2 has caused a major worldwide health crisis with high rates of morbidity and death. Interestingly, it has also been linked to cancer, which begs the issue of whether it plays a role in carcinogenesis. Recent studies have revealed various mechanisms by which SARS-CoV-2 can influence oncogenic pathways, potentially promoting cancer development. The virus encodes several proteins that alter key signaling pathways associated with cancer hallmarks. Unlike classical oncogenic viruses, which transform cells through viral oncogenes or by activating host oncogenes, SARS-CoV-2 appears to promote tumorigenesis by inhibiting tumor suppressor genes and pathways while activating survival, proliferation, and inflammation-associated signaling cascades. Bioinformatic analyses and experimental studies have identified numerous interactions between SARS-CoV-2 proteins and cellular components involved in cancer-related processes. This review explores the intricate relationship between SARS-CoV-2 infection and cancer, focusing on the regulation of key hallmarks driving initiation, promotion and progression of cancer by viral proteins. By elucidating the underlying mechanisms driving cellular transformation, the potential of SARS-CoV-2 as an oncovirus is highlighted. Comprehending these interplays is essential to enhance our understanding of COVID-19 and cancer biology and further formulating strategies to alleviate SARS-CoV-2 influence on cancer consequences.

Program: Biomedical Science (PhD)

Please refer to our student handbook for any questions!

Introduction

Hasekura Foundation researcher Nakajima Shoma (MS) doesn’t have a “prototypical” approach of a cancer researcher. He has taken a unique perspective on researching the disease, as fit for a virologist, a scientist who specializes in the study of viruses. “I’ve spent my entire academic career closely examining viruses. The pathways that cells utilize to protect themselves against viral infection, including responses to, are necessary to defend themselves from cancer,��� he says. The cell’s defense mechanism has furthered his perspective on cancer, and is connected to understanding the development of cancer.

Tumor virology is closely related to Nakajiima’s research, a field that studies viruses that cause cancer. How they interact with each other is dependent on the host cells. From studying oncogenic viruses in cancer, Nakajima has found fundamental importance in looking into cancer biology. “I was able to assess oncogenes and tumor-suppressing genes,” informs the thirty-year-old. “Some of these viruses I began engineering for bio-virology therapy, by using, of course, oncolytic viruses that can restrictively infect and kill cancerous cells.”

At the 2024 Hasekura-Kinjo Assembly, Nakajima Shoma presented an update regarding his work at a lecture. The Hasekura-Kinjo Assembly is a conference funded by researchers to network with peers in cancer research, to share prospects, and engage with established researchers. Co-funded by the Uchida Sakiko Memorial Cancer Research Fund, Nakajima leads a small team of researchers at the Yamase Cancer Center in Kyoto, Japan. His research focuses on DNA sequences as aftermaths from viral infections. “I’d like to thank the foundation for supporting my findings,” Nakajima says. “It’s been nothing but transformative, and it’s the first grant that funded our laboratory, so I’d like to thank everyone involved for making it happen.”

Nakajima Shoma’s king's pin on cell defense mechanisms against viral infections and their embryonic relevance to cancer is suggestive of his knowledge and exploration of how disordering said pathways may contribute to tumor development. His studies are indicative of his ability to harness therapeutic practices. Thus, Nakajima’s work evaluates viral pathogens interplaying with host cellular mechanisms in the wake of oncogenesis.

Entrectinib: Uses, Interactions, Mechanism of Action

Understanding Entrectinib: Uses, Mechanism of Action, and Drug Interactions

The development of targeted cancer therapies has revolutionized the approach to oncology. Among these innovative agents, entrectinib stands out as a selective inhibitor designed to target specific genetic alterations that drive cancer progression. With its ability to address multiple tumor types driven by particular gene fusions, entrectinib represents a shift toward personalized medicine in oncology.

In this blog, we will explore the key clinical uses of entrectinib, its mechanism of action, and potential drug interactions clinicians and patients should be aware of.

What Is Entrectinib?

Entrectinib is an oral small-molecule tyrosine kinase inhibitor (TKI) developed to target specific gene rearrangements that are known to promote cancer growth. It belongs to a class of medications that selectively inhibit the activity of certain proteins involved in cell signaling pathways that regulate cell proliferation and survival.

Entrectinib is notable for its ability to cross the blood-brain barrier, making it effective for cancers that have metastasized to the central nervous system (CNS), a common and difficult-to-treat site of disease in many malignancies.

Clinical Uses of Entrectinib

Entrectinib is primarily used to treat patients whose tumors harbor specific genetic alterations, namely:

NTRK Gene Fusion-Positive Solid Tumors Entrectinib is indicated for the treatment of solid tumors with a neurotrophic tyrosine receptor kinase (NTRK) gene fusion, regardless of tumor type. These fusions lead to the production of abnormal TRK fusion proteins, which drive uncontrolled cellular growth. Entrectinib is used in cases where:

There are no satisfactory alternative treatments available.

The cancer has metastasized or is inoperable.

ROS1-Positive Non-Small Cell Lung Cancer (NSCLC) In NSCLC, gene rearrangements involving ROS1 are found in a small subset of patients. These gene fusions activate oncogenic signaling pathways, making entrectinib a rational choice as a ROS1 inhibitor.

The use of entrectinib in these contexts exemplifies the growing trend of tissue-agnostic cancer therapies, which are guided more by genetic markers than by the cancer’s site of origin.

Mechanism of Action

Entrectinib acts by selectively inhibiting the tyrosine kinases encoded by the following genes:

NTRK1, NTRK2, and NTRK3: These genes encode for TRKA, TRKB, and TRKC proteins, respectively. When abnormally fused with other genes, these proteins can trigger constitutive activation of downstream signaling pathways like MAPK, PI3K-AKT, and PLCγ, leading to unchecked cell division.

ROS1: A receptor tyrosine kinase implicated in oncogenic fusion events in lung cancer.

ALK (Anaplastic Lymphoma Kinase): Entrectinib also has activity against ALK, though this is not its primary approved indication.

By blocking the ATP-binding site of these kinases, entrectinib halts downstream signaling that drives proliferation and survival of tumor cells. The compound's ability to penetrate the CNS further allows it to combat brain metastases, a significant advantage over some earlier TKIs.

Pharmacokinetics and Administration

Entrectinib is administered orally and is generally taken once daily. It undergoes metabolism primarily in the liver, predominantly via the CYP3A4 enzyme, a feature that has important implications for potential drug interactions.

The half-life of entrectinib is approximately 20 hours, supporting its once-daily dosing. Peak plasma concentrations are typically reached within 4 to 6 hours after administration.

Potential Drug Interactions

Given its metabolism via CYP3A4, entrectinib is susceptible to several significant drug interactions. These include:

1. CYP3A4 Inhibitors

Drugs that inhibit CYP3A4 can increase plasma levels of entrectinib, potentially raising the risk of toxicity. Examples include:

Ketoconazole

Itraconazole

Clarithromycin

Grapefruit juice (a dietary source)

2. CYP3A4 Inducers

Conversely, drugs that induce CYP3A4 can decrease entrectinib levels, reducing its efficacy. Examples include:

Rifampin

Carbamazepine

Phenytoin

St. John’s Wort (a common herbal supplement)

Co-administration with strong inducers is generally discouraged.

3. QT Interval-Prolonging Drugs

Entrectinib may modestly prolong the QT interval, a measurement of cardiac electrical activity. Concomitant use with other QT-prolonging drugs (e.g., certain antiarrhythmics, antipsychotics, or antibiotics) may increase the risk of arrhythmias.

4. P-glycoprotein (P-gp) Substrates

Entrectinib may inhibit P-glycoprotein, potentially increasing exposure to drugs that are P-gp substrates, such as digoxin.

Side Effects and Monitoring

Common side effects of entrectinib include:

Fatigue

Dizziness

Nausea and vomiting

Constipation

Weight gain

Anemia

More serious adverse effects can include cardiomyopathy, QT prolongation, central nervous system effects (e.g., cognitive disturbances), and skeletal fractures, particularly in pediatric populations. Regular monitoring of cardiac function, liver enzymes, and neurologic status is advised during therapy.

Conclusion

Entrectinib is a potent, targeted therapy designed for cancers driven by specific gene fusions, notably involving NTRK and ROS1. Its effectiveness across tumor types, ability to cross the blood-brain barrier, and relatively well-tolerated safety profile make it a valuable tool in modern oncology.

However, like all targeted therapies, its use must be guided by appropriate molecular diagnostics, and potential drug interactions must be carefully managed.

Is Liver Cancer Hereditary? Exploring Genetic Risk Factors

Liver cancer is a serious condition affecting thousands of people worldwide. While environmental factors such as hepatitis infection and alcohol use are well-known contributors, there's growing interest in understanding whether liver cancer can be inherited. So, is liver cancer hereditary? Let’s explore the genetic risk factors and the role they play in liver cancer development.

Understanding Liver Cancer     

Liver cancer begins in the cells of the liver. The most common type is hepatocellular carcinoma (HCC), which originates in the main liver cells (hepatocytes). Other types include intrahepatic cholangiocarcinoma and hepatoblastoma (more common in children).

Genetic vs. Environmental Causes

Cancer can be caused by genetic mutations (changes in your DNA) or external risk factors such as:

Chronic hepatitis B or C infections

Excessive alcohol use

Fatty liver disease (especially linked to obesity and diabetes)

Aflatoxin exposure (a toxin from mold-contaminated food)

But genetics can also increase your susceptibility to these environmental triggers or even cause mutations on their own.

Can Liver Cancer Be Inherited?

In most cases, liver cancer is not directly inherited, but certain genetic conditions and inherited syndromes can increase your risk. Here are a few:

1. Hemochromatosis

A genetic disorder that causes the body to absorb too much iron. Excess iron gets stored in organs including the liver, increasing the risk of cirrhosis and liver cancer.

2. Alpha-1 Antitrypsin Deficiency

This inherited condition affects the liver's ability to process certain proteins, leading to liver damage and possibly cancer.

3. Glycogen Storage Diseases

A group of inherited disorders that affect the way the body processes glycogen and can increase the risk of liver tumors.

4. Family History

Having a first-degree relative (parent, sibling, child) with liver cancer may slightly raise your risk. While it’s unclear whether this is due to shared genes, shared environments, or both, studies show a measurable increase in risk.

Genetic Mutations in Liver Cancer

In some people, mutations in tumor suppressor genes like TP53 or oncogenes such as CTNNB1 are involved in the development of liver cancer. These mutations can sometimes be inherited or can occur spontaneously due to other factors like viral infections.

Common Genetic Changes in Liver Cancer:

TP53 Mutation – Often associated with exposure to aflatoxins

CTNNB1 Mutation – Involved in WNT signaling pathway

TERT Promoter Mutations – Common in hepatocellular carcinoma

Should You Get Genetic Testing?

Genetic testing is not routinely recommended for everyone with liver cancer. However, if you have a strong family history of liver disease, cancer at a young age, or known inherited syndromes, your doctor might suggest testing.

Testing can:

Help identify your risk

Guide screening and prevention strategies

Inform family members about their risk

What Can You Do If You Have a Genetic Risk?

If you have a family history of liver cancer or a known genetic condition:

Get regular liver check-ups (ultrasounds, blood tests for AFP)

Avoid alcohol and tobacco

Get vaccinated against hepatitis B and treated for hepatitis C

Maintain a healthy weight and diet

Limit exposure to toxins and contaminated foods

Conclusion

While liver cancer is mostly linked to environmental factors, certain inherited conditions and genetic mutations can increase your risk. Knowing your family history and understanding these risks can empower you to take proactive steps toward prevention and early detection.

If you're concerned about your risk, talk to a healthcare provider or genetic counselor.

📌 Key Takeaways

Liver cancer is not typically inherited, but genetic conditions like hemochromatosis and alpha-1 antitrypsin deficiency can increase risk.

Mutations in genes like TP53 and CTNNB1 are linked to liver cancer.

Family history slightly increases your risk.

Early screening and lifestyle choices can help mitigate risk.

Molecular Oncology: The Interplay Between Viruses and Cancer

Cancer remains one of the most challenging diseases in modern medicine, affecting millions of people worldwide. While traditional treatments like chemotherapy, radiation, and surgery have been the cornerstone of cancer management, they often come with significant side effects and are not always effective. In recent years, the field of molecular oncology has emerged as a game-changer in understanding and treating cancer at the genetic and cellular level. Molecular oncology focuses on identifying the specific genetic mutations and molecular pathways that drive cancer growth, allowing researchers and clinicians to develop highly targeted therapies. These advancements have paved the way for precision medicine, where treatments are tailored to the unique genetic profile of a patient's tumor. With the advent of next-generation sequencing, targeted therapies, immunotherapy, and liquid biopsies, molecular oncology is fundamentally transforming how we diagnose, treat, and manage cancer.

The molecular oncology market is poised for significant growth over the next decade, driven by advancements in genomic research, precision medicine, and targeted cancer therapies. Valued at USD 2.3 billion in 2023, the industry is projected to expand at a CAGR of 11.0% from 2024 to 2034, reaching over USD 7.4 billion by 2034.

Key factors fueling this growth include the rising prevalence of cancer, increasing adoption of next-generation sequencing (NGS), and the growing demand for personalized treatment approaches. Additionally, innovations in liquid biopsy, biomarker discovery, and AI-driven oncology research are expected to further accelerate market expansion, making molecular oncology a cornerstone of future cancer care.

The Molecular Basis of Cancer

Cancer is fundamentally a disease of the genome, arising from genetic mutations and epigenetic changes that disrupt normal cellular functions. These changes can be inherited or acquired due to environmental factors such as smoking, UV radiation, chemical exposure, and viral infections. At the heart of cancer development are three key molecular components: oncogenes, tumor suppressor genes, and DNA repair mechanisms.

Oncogenes are genes that normally play a role in cell growth and division. When mutated or overexpressed, they become hyperactive, leading to uncontrolled cell proliferation. Examples include the KRAS gene, which is frequently mutated in lung, colorectal, and pancreatic cancers, and the MYC gene, which is implicated in aggressive cancers like Burkitt lymphoma. In contrast, tumor suppressor genes act as the body’s defense mechanisms, preventing uncontrolled cell growth. When these genes are mutated or deleted, they lose their ability to regulate cell division and apoptosis, leading to cancer progression. The TP53 gene, often referred to as the "guardian of the genome," is the most commonly mutated tumor suppressor in human cancers. It plays a critical role in DNA repair, cell cycle regulation, and apoptosis. When TP53 is inactivated, damaged cells survive and proliferate, increasing the risk of tumor development.

Another crucial aspect of cancer biology is DNA repair mechanisms. The human body constantly repairs DNA damage through various pathways, such as mismatch repair (MMR) and homologous recombination repair (HRR). Defects in these repair systems lead to genomic instability and increase cancer susceptibility. For instance, mutations in BRCA1 and BRCA2 impair the DNA repair process, significantly raising the risk of breast and ovarian cancers. In addition to genetic mutations, epigenetic modifications—such as changes in DNA methylation and histone modifications—can also contribute to cancer progression. These changes can silence tumor suppressor genes or activate oncogenes, further driving malignancy.

Advancements in Molecular Oncology

Next-Generation Sequencing (NGS) and Genomic Profiling

The development of next-generation sequencing (NGS) has revolutionized the field of molecular oncology. This technology allows scientists to analyze entire genomes, transcriptomes, and epigenomes in a high-throughput manner, identifying key mutations and molecular alterations in individual tumors. NGS has led to the discovery of actionable mutations in various cancers, enabling oncologists to select the most effective targeted therapies. For example, in lung cancer, NGS can detect mutations in EGFR, ALK, and ROS1, guiding the use of specific inhibitors like erlotinib, crizotinib, and lorlatinib. Genomic profiling has also been instrumental in classifying tumors into molecular subtypes, leading to more precise treatment decisions and improved patient outcomes.

Targeted Therapies: Precision Medicine in Action

One of the biggest breakthroughs in molecular oncology is the development of targeted therapies, which attack cancer cells based on their specific genetic alterations while sparing healthy cells. Unlike chemotherapy, which indiscriminately kills rapidly dividing cells and causes significant side effects, targeted therapies are designed to interfere with specific molecular pathways that drive cancer growth.

One of the earliest success stories in targeted therapy was imatinib (Gleevec), which transformed the treatment of chronic myeloid leukemia (CML) by inhibiting the BCR-ABL fusion protein. Since then, numerous targeted therapies have been developed. Tyrosine kinase inhibitors (TKIs), such as gefitinib and erlotinib, are highly effective in treating EGFR-mutant lung cancer. HER2-targeted monoclonal antibodies, like trastuzumab (Herceptin), have dramatically improved survival rates for HER2-positive breast cancer patients. PARP inhibitors, such as olaparib and rucaparib, are now widely used for BRCA-mutated ovarian and breast cancers by exploiting their defective DNA repair mechanisms.

Immunotherapy and Its Role in Molecular Oncology

While targeted therapies have significantly improved treatment outcomes, immunotherapy has emerged as another revolutionary approach in molecular oncology. Unlike traditional treatments that directly attack cancer cells, immunotherapy enhances the body’s immune system to recognize and destroy cancer cells. One of the most important breakthroughs in this field is the development of immune checkpoint inhibitors, which block proteins like PD-1, PD-L1, and CTLA-4, preventing cancer cells from evading immune detection. Drugs like pembrolizumab (Keytruda) and nivolumab (Opdivo) have been life-changing for patients with melanoma, lung cancer, and other malignancies.

Another promising innovation is CAR-T cell therapy, which involves genetically modifying a patient’s T cells to recognize and attack cancer cells. CAR-T therapy has shown remarkable success in treating blood cancers like leukemia and lymphoma, with long-term remissions in some patients. As research continues, scientists are exploring ways to extend the benefits of immunotherapy to solid tumors and minimize immune-related side effects.

Liquid Biopsies: A Non-Invasive Approach to Cancer Detection

A major challenge in oncology has been the difficulty of obtaining tumor tissue for genetic analysis. Traditional biopsies are invasive and sometimes not feasible, especially for deep-seated tumors. Liquid biopsies offer a revolutionary solution by detecting circulating tumor DNA (ctDNA), tumor-derived exosomes, and other biomarkers in the blood. This technology allows for early cancer detection, treatment monitoring, and identification of drug resistance without requiring invasive procedures. Liquid biopsies are particularly useful for tracking minimal residual disease (MRD) and detecting relapse earlier than imaging techniques. Companies like Guardant Health and Foundation Medicine have developed commercial liquid biopsy tests that are transforming cancer care.

Challenges and Future Directions

Despite the remarkable progress in molecular oncology, several challenges remain. One major issue is tumor heterogeneity, where different parts of the same tumor may have distinct genetic profiles, making treatment more complicated. Drug resistance is another obstacle, as cancer cells can evolve and develop mechanisms to evade targeted therapies. Additionally, while molecular testing and precision medicine have improved outcomes, not all patients have access to these cutting-edge treatments due to cost and availability issues.

Looking ahead, researchers are working to identify new biomarkers for early cancer detection, develop combination therapies to prevent resistance, and integrate artificial intelligence (AI) and machine learning to analyze complex genomic data for better treatment decisions. The future of molecular oncology lies in personalized, data-driven cancer treatment, bringing us closer to more effective and less toxic cancer therapies.

Deciphering the Ras/MAPK Signaling Pathway in the Progression and Treatment of Hepatocellular Carcinoma_Crimson Publishers

Abstract

Hepatocellular Carcinoma (HCC) is a serious health issue and its frequency is rapidly escalating throughout the world therefore researchers have focused more attention to the Ras/MAPK signaling pathway. The signaling pathways are linked to develop tumors and the Ras/MAPK pathway is one of these pathways, activated in 60% of HCCs with poor prognosis. A number of different proteins causes the abnormal regulation of the MAPK pathway in HCC. Ras, a small GTPase and Raf are the most commonly mutated oncogene supports the critical function of this pathway in oncogenesis. The genetic mutations leading to effector molecule to permanently activated in the Ras/MAPK signaling cascades. The inappropriate activation of this pathway is primarily due to the downregulation of various Ras/MAPK pathway inhibitors including RASSF proteins, GAPs, DUSP1, Spred and Sprouty proteins. The post-transcriptional or epigenetic processes downregulate these cancer suppressor genes. The aim of current study on the primary mutations resulting in aberrant activation of Ras/MAPK pathway and their role on the initiation and progression of HCC. It also offers an update on the various inhibitors to target this central signaling pathway including various Ras, Raf, MEK inhibitors in the context of HCC. Finally, we evaluate the available options for treatment in this context.
