High levels of circulating folate concentrations are associated with DNA methylation of tumor suppressor and repair genes p16, MLH1, and MGMT in elderly Chileans

Clinical Epigenetics, 2017
Background Changes in DNA methylation, one of the most studied epigenetic mechanisms, are considered an initial marker for early cancer detection.

In vivo genome‐editing screen identifies tumor suppressor genes that cooperate with Trp53 loss during mammary tumorigenesis

Molecular Oncology, 2022
Breast cancer is a heterogeneous disease that comprises multiple histological and molecular subtypes. To gain insight into mutations that drive breast tumorigenesis, we describe a pipeline for the identification and validation of tumor suppressor genes ...

Identification of Head and Neck Cancer Subtypes Based on Human Papillomavirus Presence and E2F-Regulated Gene Expression

mSphere, 2018
Human papillomavirus (HPV) is present in a subset of head and neck squamous cell carcinomas (HNSCCs). The cell cycle regulatory Rb-E2F pathway is a major target of HPV and is perturbed by these viruses in cell culture and animal models, as well as in ...

Mutant p53 and ETS2, a tale of reciprocity

Frontiers in Oncology, 2016
TP53 is one of the most frequently inactivated tumor suppressor genes in human cancer. However, unlike other tumor suppressor genes whose expression is lost, TP53 is usually inactivated as a result of a single nucleotide change within the coding region.

Promoter hypermethylation of p16 and APC in gastrointestinal cancer patients

The Turkish Journal of Gastroenterology, 2014
Background/Aims: Cancer is a consequence of the disruption of cellular regulation. Epigenetic is one of the reasons of this disruption. Epigenetic factors play a role in the carcinogenesis by affecting proto-oncogenes and tumor suppressor genes and it is

Loss of Mitochondrial Tumor Suppressor Genes Expression Is Associated with Unfavorable Clinical Outcome in Head and Neck Squamous Cell Carcinoma: Data from Retrospective Study. [PDF]

PLoS ONE, 2016
Mitochondrial genes play important roles in cellular energy metabolism, free radical generation, and apoptosis. Dysregulation of these genes have long been suspected to contribute to the generation of reactive oxygen species (ROS), increased ...

Cancer: Disease Caused by Alteration of Genes [PDF]

International Journal of Basic Science in Medicine, 2016
In normal cells when genetic defects occur, there are some sensitive mechanisms through which the defect might be repaired or apoptosis might be induced.

Oncogenic context shapes the fitness landscape of tumor suppression

Nature Communications, 2023
Tumors acquire alterations in oncogenes and tumor suppressor genes in an adaptive walk through the fitness landscape of tumorigenesis. However, the interactions between oncogenes and tumor suppressor genes that shape this landscape remain poorly resolved

The role of histone deacetylases in human gastrointestinal and associated glands cancer [PDF]

Journal of Advanced Biomedical Sciences, 2019
Background & Objective: In the eukaryotic cells, the DNA wraps around the histone proteins (H2A, H2B, H3, and H4) and constitutes the nucleosome. Chromatin organization plays a major role in the control of gene expression.
