Regulatory pathways involving non-coding RNAs (ncRNAs), such as microRNAs (miRNAs) and long non-coding RNAs (lncRNA), have gained great relevance due to their role in the control of gene expression modulation. Using RNA sequencing of KSHV Bac36 transfected mouse endothelial cells (mECK36) and tumors, we have analyzed the host and viral transcriptome to uncover the role lncRNA-miRNA-mRNA driven networks in KSHV tumorigenesis. The integration of the differentially expressed ncRNAs, with an exhaustive computational analysis of their experimentally supported targets, led us to dissect complex networks integrated by the cancer-related lncRNAs Malat1, Neat1, H19, Meg3, and their associated miRNA-target pairs. These networks would modulate pathways related to KSHV pathogenesis, such as viral carcinogenesis, p53 signaling, RNA surveillance, and cell cycle control. Finally, the ncRNA-mRNA analysis allowed us to develop signatures that can be used to an appropriate identification of druggable gene or networks defining relevant AIDS-KS therapeutic targets.

Phthalate esters (PAEs) are ubiquitous environmental contaminants, with certain congeners potentially exhibiting breast cancer-promoting effects. However, their toxicological mechanisms remain poorly characterized. This study systematically investigates PAEs' direct interactions with breast cancer pathways using an integrated computational approach combining molecular docking-based inverse virtual screening with network toxicology.

Primary effusion lymphoma (PEL) is a rare B-cell lymphoma with an extremely poor prognosis that is associated with long-term persistent latent infection with Kaposi's sarcoma-associated herpesvirus (KSHV) and Epstein-Barr virus (EBV). However, studies on the correlation between KSHV genotype and PEL development in elderly patients are still lacking. We present the first global case of non-HIV, non-effusive, difficult-to-diagnose PEL with disseminated Kaposi's sarcoma (KS) in an elderly patient of Bouyei nationality, dynamically demonstrating that KSHV and EBV co-infection promote tumorigenesis.

Kaposi's sarcoma-associated herpesvirus (KSHV) is a human double-stranded DNA virus that is responsible for the development of Kaposi's sarcoma (KS), primary effusion lymphoma (PEL), multicentric Castleman's disease (MCD), and KSHV inflammatory cytokine syndrome (KICS). KSHV infection manipulates distinct cellular proteins and signaling pathways, resulting in immune escape, cell death inhibition, infinite cell growth, and cancer formation. Current treatments for KSHV-associated cancers are limited to conventional strategies targeting nonviral cancers which encounter limited efficacy and drug resistance.

Herpesviruses are DNA viruses that evade the immune response and persist as lifelong infections. Human gamma-herpesviruses Epstein-Barr virus (EBV) and Kaposi's sarcoma herpesvirus (KSHV) are oncogenic; they can lead to cancer. Oncogenic viruses are responsible for 10-15% of human cancer development, which can have poor prognoses.

Oncoviruses, such as Epstein-Barr virus (EBV), human papillomavirus (HPV), and Kaposi sarcoma-associated herpesvirus (KSHV), have been widely discussed for their oncogenic risk. Initially, the oral cavity was disregarded. In recent years, orientation has shifted to the importance of the oral cavity and cancer-related issues via Handbook 19 titled "Oral Cancer Prevention" by the International Agency for Research on Cancer, the WHO Global Oral Health Status Report 2022, and multiple other actions focused on reducing the oversight of this neglected area.
