Infections account for approximately 15% of human cancers worldwide. Viruses are the most predominant infectious agents and can infect and alter various types of human cells thereby leading to the development of various forms of cancer. Current studies have reported that Epstein-Barr virus (EBV), hepatitis B virus (HBV), hepatitis C virus (HBC), human papillomavirus (HPV), Kaposi's sarcoma-associated herpesvirus (KSHV), human T-lymphotropic virus 1 (HTLV-1), Markel cell polyomavirus (MCPyV), and BK polyomavirus are the most important oncogenic viruses that are directly involved in the initiation and progression of cancer. Additionally, some recent studies have also reported that some non-oncogenic viruses, such as COVID-19 causing SARS-CoV-2, HIV and Dengue may potentially facilitate the onset of cancer. In this review, we outline the current knowledge of the molecular machinery of viral infection, and how viral oncogenic proteins play a specific role in cellular transformation as well as oncogenesis. Here, we have also discussed the available preventive and treatment approaches for viral infection and oncogenesis. This review will further help in the making of a roadmap for future research and the development of effective therapies such as precision medicine, gene therapies, vaccine development, and immunotherapy.

The increasing incidence and mortality rates of HPV-positive cancers, particularly HPV-positive head and neck cancer, in recent years have emphasized the pressing need for more efficacious treatment options. Recent studies have elucidated the molecular distinctions between HPV-positive and HPV-negative cancers, which are crucial for developing precise and effective therapeutic strategies. This review updates the most recent findings on the molecular variances between HPV-positive and HPV-negative cancers, evaluates current treatments for HPV-positive cancers, and summarizes emerging frontiers in HPV-targeted therapies aimed at developing more effective and precise interventions against these cancers.

Naturally, a wide range of genetic and environmental variables predominate, such as bacterial, viral and parasite infective entities that have been identified as carcinogenic bioagents. Many helminth and protozoan parasitic diseases are liable to cause human cancer. Conveniently, three trematode parasites viz.

Human Papillomavirus (HPV) is linked to multiple cancers, most significantly cervical cancer, for which HPV infection is associated with nearly all cases. Essential to the oncogenesis of HPV is the function of the viral protein E6 and its role in degrading the cell cycle regulator p53. Degradation of p53, and the resultant loss of cell cycle control, is mediated by E6 recruitment of the E3 ubiquitin ligase E6AP and subsequent ubiquitination of p53.

Microplastic particles have become ubiquitous in various ecosystems due to a drastic increase in plastic use and its consequent litter. The biological effects of these plastic particles on aquatic fauna are well-documented. However, the study of their accumulation and subsequent impact on terrestrial flora and fauna is in its initial stages.

Background: Gastric carcinogenesis is associated with defects in DNA damage repair pathways, in which the gene family (, , and ) play an important role in DNA repair. It is also well known that the gene, as a tumor suppressor, influences the development of gastric cancer.
Methods: We recruited 484 gastric cancer patients and 471 controls.
