Epigenetic Silencing of the MLH1 Promoter in Relation to the Development of Gastric Cancer and its use as a Biomarker for Patients with Microsatellite Instability: a Systematic Analysis

Cellular Physiology and Biochemistry, 2018
Background/Aims: Human mutL homolog 1 (MLH1) promoter methylation was reported in gastric cancer (GC). This study determined the clinicopathological, prognostic, and diagnostic effects of MLH1 promoter methylation in GC. Methods: The combined odds ratio (

A Novel Nomogram Incorporating the Aggregate Index of Systemic Inflammation, Clinicopathological Parameters and Molecular Classification to Predict Recurrence of Endometrial Cancer: A Multi‐Center Retrospective Study

Cancer Medicine, Volume 15, Issue 5, May 2026.
ABSTRACT This study evaluated the aggregate index of systemic inflammation (AISI) for predicting postoperative recurrence in endometrial cancer (EC). A total of 1557 patients were enrolled and divided into training (n = 1030) and validation (n = 527) cohorts. The optimal AISI cutoff was determined by ROC curve analysis.

Advanced Gastric Cancer Presenting as a Giant Subepithelial Lesion: A Case Report

Clinical Case Reports, Volume 14, Issue 5, May 2026.
A giant subepithelial lesion. ABSTRACT Gastric cancer may occasionally present with a subepithelial lesion‐like appearance. When a gastric gastrointestinal stromal tumor (GIST) is suspected preoperatively without definitive pathological confirmation, intraoperative frozen section analysis is recommended to prevent inappropriate surgical intervention.

Methylation-sensitive high-resolution melting technology is a simple and sensitive method to detect germline epimutation of the MLH1 gene promoter

Clinical Epigenetics
Background Lynch syndrome is an autosomal dominant cancer predisposition syndrome classically caused by germline mutations of the mismatch repair genes MLH1, MSH2, MSH6 and PMS2.

Downregulation of SPTAN1 is related to MLH1 deficiency and metastasis in colorectal cancer.

PLoS ONE, 2019
IntroductionColorectal cancers (CRCs) deficient in the DNA mismatch repair protein MutL homolog 1 (MLH1) display distinct clinicopathological features and require a different therapeutic approach compared to CRCs with MLH1 proficiency.

Silencing of the DNA Mismatch Repair Gene MLH1 Induced by Hypoxic Stress in a Pathway Dependent on the Histone Demethylase LSD1

Cell Reports, 2014
Silencing of MLH1 is frequently seen in sporadic colorectal cancers. We show here that hypoxia causes decreased histone H3 lysine 4 (H3K4) methylation at the MLH1 promoter via the action of the H3K4 demethylases LSD1 and PLU-1 and promotes durable long ...

Clinical Significance of Biomarkers in Oropharyngeal Squamous Cell Carcinoma: Recurrence Prediction and Treatment Response

Cancer Reports, Volume 9, Issue 5, May 2026.
ABSTRACT Background Oropharyngeal squamous cell carcinoma (OPSCC) accounts for a substantial proportion of head and neck cancers, with a rising incidence largely driven by human papillomavirus (HPV) infection. Despite advances in multimodal treatment, disease recurrence remains common and limits long‐term survival, highlighting the need for reliable ...

Outcomes from the English National Lynch Syndrome transformation project

International Journal of Cancer, Volume 158, Issue 9, Page 2369-2379, 1 May 2026.
What's new? The elevated cancer risk conferred by Lynch syndrome can be mitigated through preventive interventions. However, Lynch syndrome often goes underdiagnosed. The National Lynch Syndrome Transformation Project in England aims to ensure that patients newly diagnosed with colorectal or endometrial cancer are offered testing for the syndrome ...

Treatment Response and Outcomes of Prostate Cancer Patients Carrying the Germline MMS22L F722fs Mutation

The Prostate, Volume 86, Issue 6, Page 727-731, May 2026.
ABSTRACT Background Methyl Methanesulfonate‐Sensitivity Protein 22‐Like (MMS22L) plays a key role in homology‐directed DNA repair, and experimental models have shown that its loss confers sensitivity to Poly (ADP‐ribose) polymerase inhibitors (PARPi).

Genetic variation in genes interacting with BRCA1/2 and risk of breast cancer in Cypriot population. [PDF]

, 2010
Inability to correctly repair DNA damage is known to play a role in the development of breast cancer. Single nucleotide polymorphisms (SNPs) of DNA repair genes have been identified, which modify the DNA repair capacity, which in turn may affect the risk
