N‐terminus of hMLH1 confers interaction of hMutLα and hMutLβ with hMutSα [PDF]

, 2006
Mismatch repair is a highly conserved system that ensures replication fidelity by repairing mispairs after DNA synthesis. In humans, the two protein heterodimers hMutSα (hMSH2‐hMSH6) and hMutLα (hMLH1‐hPMS2) constitute the centre of the repair reaction ...

Dysplasia in sessile serrated lesions: frequency, interobserver variability and added value of immunohistochemistry

Histopathology, EarlyView.
Sessile serrated lesions with dysplasia represent a critical step in colorectal carcinogenesis. While routine histologic diagnosis is generally reliable and positive diagnostic trends are observed, subtle dysplastic changes may be overlooked. Targeted use of MLH1 immunohistochemistry provides meaningful diagnostic support in selected sessile serrated ...

Aberrant PRDM2 methylation as an early event in serrated lesions destined to evolve into microsatellite‐instable colorectal cancers

The Journal of Pathology: Clinical Research
Up to 30% of colorectal cancers (CRCs) develop from sessile serrated lesions (SSLs). Within the serrated neoplasia pathway, at least two principally distinct oncogenetic routes exist generating microsatellite‐stable and microsatellite‐instable CRCs ...

The conserved XPF:ERCC1-like Zip2:Spo16 complex controls meiotic crossover formation through structure-specific DNA binding. [PDF]

, 2019
In eukaryotic meiosis, generation of haploid gametes depends on the formation of inter-homolog crossovers, which enable the pairing, physical linkage, and eventual segregation of homologs in the meiosis I division.

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 ...

BRIP-1 germline mutation and its role in colon cancer: presentation of two case reports and review of literature. [PDF]

, 2019
BackgroundHereditary colon cancer is characterized by the inheritance of an abnormal gene mutation which predisposes to malignancy. Recent advances in genomic medicine have identified mutations in "novel" genes as conferring an increased risk of ...

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.

Immune, molecular and genetic profiles of gastric signet ring cell carcinoma: Recent progress and future challenges

International Journal of Cancer, Volume 159, Issue 1, Page 11-29, 1 July 2026.
Abstract Gastric signet ring cell carcinoma (GSRCC) is a special type of gastric cancer common in young women. Diffuse gastric cancer (DGC) begins with intramucosal lesions comprising differentiated GSRCC cells. Genetically, GSRCC and DGC are clonally identical, with their morphology influenced by extracellular Wnt signaling.

Homeobox B13 activates the hypoxia‐inducible factor 1 pathway through histone lactylation thereby reprogramming lipid metabolism and promoting sorafenib resistance in hepatocellular carcinoma

Journal of Cell Communication and Signaling, Volume 20, Issue 2, June 2026.
Lactylation‐mediated metabolism reprogramming in HCC sorafenib resistance. In sorafenib‐resistant hepatocellular carcinoma (HCC) cells, lactate accumulation drives histone H3 lysine 18 lactylation (H3K18la). This modification is specifically enriched in the promoter region of homeobox B13 (HOXB13), activating HOXB13 transcription and upregulating its ...
