Exome Sequencing Identifies Variants in MLH1 and ERBB2 as Potential Cancer‐Predisposing Factors in Familial Early‐Onset Colorectal Cancer

The Kaohsiung Journal of Medical Sciences, EarlyView.
ABSTRACT Colorectal cancer (CRC) has raised considerable health concerns worldwide, with increasing incidence rates, specifically among younger populations. Despite remarkable progress in diagnosing and treating various diseases, the genetic basis of CRC remains only partially understood.

The properties of Msh2-Msh6 ATP binding mutants suggest a signal amplification mechanism in DNA mismatch repair. [PDF]

, 2018
DNA mismatch repair (MMR) corrects mispaired DNA bases and small insertion/deletion loops generated by DNA replication errors. After binding a mispair, the eukaryotic mispair recognition complex Msh2-Msh6 binds ATP in both of its nucleotide-binding sites,

Genetic analysis of primary lung interdigitating dendritic cell sarcomas

The Journal of Pathology, EarlyView.
Abstract Interdigitating dendritic cell sarcomas (IDCSs) are rare tumors that commonly arise in the hematopoietic system and rarely outside. The genetic drivers of IDCS carcinogenesis are unknown; therefore, therapeutic options are limited. We investigated somatic gene mutations and copy‐number alterations (CNAs) in nine IDCSs arising in the lung by ...

BRAFV600E mutation and its association with clinicopathological features of colorectal cancer: a systematic review and meta-analysis.

PLoS ONE, 2014
BackgroundColorectal cancer (CRC) is a heterogeneous disease with multiple underlying causative genetic mutations. The B-type Raf proto-oncogene (BRAF) plays an important role in the mitogen-activated protein kinase (MAPK) signaling cascade during CRC ...

What Happens After Menopause (WHAM)? A Progress Report of a Prospective Controlled Study of Women After Pre‐Menopausal Risk‐Reducing Bilateral Salpingo‐Oophorectomy

BJOG: An International Journal of Obstetrics &Gynaecology, EarlyView.
ABSTRACT Surgical menopause, the removal of both ovaries prior to natural menopause, may impact short‐and long‐term physical and emotional health. An increasingly common cause of surgical menopause is risk‐reducing salpingo‐oophorectomy (RRSO) in those at high inherited risk of ovarian cancer.

Incidental Colorectal Adenomas in Adolescents: Clinical Management, Genetic Evaluation, and Surveillance

Journal of Gastroenterology and Hepatology, EarlyView.
Adolescents with incidental colorectal adenomas require age‐conscious management balancing referral for genetic counseling with evidence‐based surveillance. This narrative review proposes a pragmatic clinical algorithm integrating adenoma characteristics, hereditary risk assessment, and guideline‐concordant follow‐up to support individualized ...

Depleted-MLH1 Expression Predicts Prognosis and Immunotherapeutic Efficacy in Uterine Corpus Endometrial Cancer: An In Silico Approach

BioMedInformatics
Uterine corpus endometrial carcinoma (UCEC) poses significant clinical challenges due to its high incidence and poor prognosis, exacerbated by the lack of effective screening methods.

Oxidative Stress and DNA Epigenetic Modifications in Cancer: Mechanisms and Targeted Therapeutics

MedComm – Oncology, Volume 5, Issue 2, June 2026.
Reactive oxygen species (ROS) modulate DNA methyltransferases (DNMTs), ten‐eleven translocation family proteins (TETs) and their cofactors, reshaping 5‐methylcytosine (5mC)/5‐hydroxymethylcytosine (5hmC)/5‐formylcytosine (5fC) landscapes and gene expression in cancer cells. In turn, epigenetic control of antioxidant and metabolic pathways feeds back on

Molecular classification of microsatellite-instable colorectal cancers reveals distinct predictors of immunotherapy response

ESMO Gastrointestinal Oncology
Microsatellite-instable (MSI) tumours constitute one-fifth of colorectal cancers (CRCs). However, the MSI CRCs display substantial tumour microenvironment (TME) heterogeneity and variable responses to immunotherapy, necessitating a refined classification

DNA Checkpoint and Repair Factors Are Nuclear Sensors for Intracellular Organelle Stresses-Inflammations and Cancers Can Have High Genomic Risks. [PDF]

, 2018
Under inflammatory conditions, inflammatory cells release reactive oxygen species (ROS) and reactive nitrogen species (RNS) which cause DNA damage. If not appropriately repaired, DNA damage leads to gene mutations and genomic instability.
