In silico prediction of COVID-19 cytokine storm in lung cancer types.

Lung cancer is one of the most frequently diagnosed malignant tumors and the leading cause of cancer-related death worldwide. Mainly, Non-small-cell lung cancer (NSCLC), which accounts for more than eighty-five percent of all lung cancers, consists of two major subtypes: lung adenocarcinoma (LUAD) and squamous cell carcinoma (LUSC). Novel coronavirus disease (COVID-19) affected millions of people caused by acute respiratory syndrome coronavirus type 2 (SARS-CoV-2) around the globe. Lung cancer patients and COVID-19 present unique and unfortunate lethal combinations because the lungs are the primary target organ of SARS-CoV-2 infection. Clinical studies have demonstrated that an over-activated inflammatory response associated with severe COVID-19 cases is characterized by excessive auto-amplifying cytokine release, which is defined as a "cytokine storm." ACE2 and TMPRSS2 receptors play an essential role in SARS-CoV-2 infection; therefore, using in silico analysis, we did correlation analysis with immune infiltration markers in LUAD and LUSC patient groups. Our study identified a promising correlation between immune-modulators and receptor proteins (ACE-2 and TMPRSS2), creating a domain that requires further laboratory studies for clinical authentication.

Harnessing the role of epigenetic histone modification in targeting head and neck squamous cell carcinoma.

Head and neck squamous cell carcinoma (HNSCC) is the sixth most prevalent form of cancer worldwide. Despite advancements made in treatment strategies, the fatality rate of HNSCC is very high. An accumulating body of evidence suggests that epigenetic modification of histones plays an influential role in the development and progression of the disease. In this review we discuss the role of epigenetic modifications in HNSCC and the inter-relationships of human papillomavirus oncoproteins and histone-modifying agents. Further, we explore the possibility of identifying these modifications as biomarkers for their use as drugs in treatment strategies.

Head and neck squamous cell carcinoma (HNSCC) is the most common kind of head and neck cancer. HNSCC can develop therapeutic resistance, making therapy more difficult. Many studies have found that epigenetic events play a key role in HNSCC. Better understanding epigenetic regulation could help discovery of biomarkers that help detect and diagnose HNSCC. This review will present recent studies, showing the importance of epigenetic regulation targeting histone modifications in the development of HNSCC.
