Multi-gene epigenetic silencing of tumor suppressor genes in T-cell lymphoma cells; delayed expression of the p16 protein upon reversal of the silencing

, 2006
Udgivelsesdato: 2006-MarTo understand better T-cell lymphomagenesis, we examined promoter CpG methylation and mRNA expression of closely related genes encoding p16, p15, and p14 tumor suppressor genes in cultured malignant T-cells that were derived from ...

Suppression of Retinal Neovascularisation by Tetrahedral Framework Nucleic Acids‐Resveratrol Via Dual Anti‐Angiogenesis and Anti‐Inflammation

Cell Proliferation, EarlyView.
Resveratrol‐loaded tetrahedral framework nucleic acids (tFNAs‐RSV) enable concurrent anti‐angiogenic and anti‐inflammatory therapy, enhancing ocular delivery and bioactivity. In hypoxia‐induced retinal neovascularisation, tFNAs‐RSV reduce neovascular lesions, vascular leakage and inflammatory infiltration by suppressing HIF‐1, p38 MAPK and NF‐κB p65 ...

High frequency of p 16 promoter methylation in non-small cell lung carcinomas from Chile

Biological Research, 2007
The inactivation of tumour suppressor genes by aberrant methylation of promoter regions has been described as a frequent event in neoplasia development, including lung cancer.

Zeb2 Controls Retinal Physiological and Pathological Angiogenesis by Regulating Astrocyte Proliferation and Differentiation

Cell Proliferation, EarlyView.
During development, the oxygen‐sensitive transcription factor Zeb2 restrains astrocyte proliferation and maturation to ensure balanced retinal angiogenesis. In disease, it promotes the neurotoxic A1 astrocyte phenotype and inflammation, thereby promoting reparative revascularization over pathological neovascularization.

High Uric Acid Promotes Stem Leydig Cell Senescence by CCDC90B Mediates Mitochondrial Quality Control Imbalance

Cell Proliferation, EarlyView.
In hyperuricemia, uric acid inhibits CCDC90B ubiquitination degradation by binding to it. Excessive CCDC90B induces mitochondrial calcium overload, leading to mitochondrial quality control imbalance and ultimately resulting in SLC senescence and decreased testosterone levels.

HPV42 – a human papillomavirus classified as a low‐risk type with oncogenic potential

JDDG: Journal der Deutschen Dermatologischen Gesellschaft, EarlyView.
Summary Human papillomavirus (HPV) type 42 is a rare HPV type currently classified as “low‐risk” and belongs to the alpha genus. It has primarily been detected in benign vulvar papillomas and is predominantly associated with benign lesions such as anogenital warts.

Mechanisms underpinning the progression of nondysplastic Barrett's oesophagus to cancer

The FEBS Journal, EarlyView.
Barrett's oesophagus confers a low but significant cancer risk. The condition is common but we do not have effective biomarkers to identify susceptible patients. We believe that there is no single factor that determines cancer risk and an understanding of the combinations of interactions (via gene expression and natural selection) between the Barrett's

Correlation between Methylation and Expression Level of P15 and P16 Genes during Differentiation of Cord Blood Stem Cells into Erythroid Lineage Mediated by Erythropoietin

Novelty in Biomedicine, 2015
Background: Several influential factors such as transcription factors and intracellular signaling components are involved in differentiation of stem cells into a specific lineage. P15 and p16 proteins are among these factors.

Hippo pathway disruption and YAP1 activation in anogenital papillary squamous intraepithelial lesion

Histopathology, EarlyView.
Disruption of the Hippo Pathway with YAP1 activation is a consistent finding in papillary squamous intraepithelial lesions and may underlie their altered epithelial maturation and HPV E6/E7 expression patterns, providing new insight into the pathogenesis of this distinct low‐risk HPV‐associated lesion.

Merkel cell carcinoma: an updated guide for pathologists

Histopathology, EarlyView.
Merkel cell carcinoma (MCC) is an aggressive cutaneous neuroendocrine carcinoma for which the differential diagnosis can include other small cell malignancies (especially metastatic small cell carcinoma) or cutaneous carcinoma. Morphologic and immunophenotypic aberrancies in MCC can increase diagnostic challenge.
