PVT1 lincRNA signals an androgen‐dependent transcriptional activation program of oncogenes in prostate cancer cells

International Journal of Cancer, Volume 159, Issue 1, Page 144-158, 1 July 2026.
What's New? Unraveling the networks that regulate androgen receptor (AR) function is critical to better understanding prostate cancer development and progression. Of particular interest in this regard is the long non‐coding RNA PVT1, which regulates gene expression in cancer and is upregulated in prostate tumors.

Oxidative Stress Induced Senescent Macrophage‐Driven Squamous Cell Carcinoma Invasion via Glutamine Metabolic Reprogramming

Aging Cell, Volume 25, Issue 7, July 2026.
Oxidative stress induces GLS2‐dependent IL‐1β secretion in senescent macrophages, promoting SCC invasion through the IL‐1β/IL‐1R2 axis. Targeting IL‐1β suppresses invasion more effectively than GLS2 inhibition, highlighting a potential therapeutic strategy for SCC.

A Constellation of Fluorescent Biosensors to Illuminate the Galaxy of Protein Kinases

ChemBioChem, Volume 27, Issue 11, 15 June 2026.
Protein kinases (PKs) are enzymes that catalyze phosphorylation of protein substrates involved in a wide variety of biological signalling pathways. This review describes the different families and mechanisms of action and regulation of protein kinases, together with the different classes of fluorescent biosensors that have been engineered and ...

Review of alterations of the cyclin-dependent kinase inhibitor INK4 family genes p15, p16, p18 and p19 in human leukemia–lymphoma cells [PDF]

Leukemia, 1998
The cyclin-dependent kinase inhibitors known as p15, p16, p18 and p19 have been suggested as candidates for tumor suppressor genes. The main genetic alterations are deletions (bi- or monoallelic) or 5' CpG island methylation of p15 and p16; very few cases or cell lines had p18 or p19 deletions or hypermethylation.

Estudo genético do gene p16 pela técnica de PCR-SSCP e expressão de proteína p16 em melanomas de mucosa oral e melanomas cutâneos Genetic analysis of p16 gene by PCR-SSCP technique and protein p16 expression in oral mucosa and skin melanomas

Anais Brasileiros de Dermatologia, 2006
FUNDAMENTOS: A deleção e mutação do gene CDKN2a que codifica um inibidor específico da ciclina dependente de quinase 4, a proteína p16, têm sido implicadas na tumorigênese do melanoma cutâneo. Entretanto, pouco se conhece sobre essas alterações genéticas

Evaluation of p16 and Ki67 expression in cervical neoplasm and its association with human papillomavirus infection: An observational study

Journal of Indira Gandhi Institute of Medical Sciences
Introduction: Cervical cancer is the fourth-most common cancer among females associated with strong viral etiology. Nearly 99.7% of cases are associated with persistent high-risk human papillomavirus infection (hr-HPV).

Fermented Porcine Placenta and Its Dipeptides Modulate Cellular Senescence in Human Keratinocytes

Current Issues in Molecular Biology
Skin aging is primarily driven by oxidative stress, mitochondrial dysfunction, and cell cycle dysregulation. This study investigated the anti-senescence effects of fermented porcine placenta (FPP) and its dipeptides, leucine–glycine (LG) and proline ...

RNA splicing variants of the novel long non-coding RNA, CyKILR, possess divergent biological functions in non-small cell lung cancer

Molecular Therapy: Nucleic Acids
The CDKN2A gene, responsible for encoding the tumor suppressors p16(INK4A) and p14(ARF), is frequently inactivated in non-small cell lung cancer (NSCLC). Herein, an uncharacterized long non-coding RNA (lncRNA) (ENSG00000267053) on chromosome 19p13.12 was

Analysis of p16 gene mutations and deletions in childhood acute lymphoblastic leukemias

São Paulo Medical Journal
CONTEXT: The p16 tumor suppressor gene encodes a cyclin-dependent kinase 4 inhibitor that blocks cell division during the G1 phase of the cell cycle. Alterations in this gene have been reported for various neoplasia types, including acute lymphoblastic ...
