Hypermethylation of tumor suppressor genes in cancer

Seminars in Cancer Biology, 1999
Hypermethylation of tumor suppressor genes and other genes functionally important in the neoplastic process is a recently recognized process. This epigenetic process is characterized by loss of function of these genes associated with transcriptional loss in the absence of structural alterations.

A multilevel perspective on MSH6‐associated Lynch syndrome: Integrating molecular, biological, and clinical insights

International Journal of Cancer, EarlyView.
Abstract Lynch syndrome (LS) is the most common hereditary colorectal cancer syndrome, caused by a germline pathogenic variant in one of the mismatch repair (MMR) genes. Among these, MSH6‐associated LS represents a distinct subtype with unique molecular and clinical characteristics.

Epigenetic Dysregulation of Somatostatin Receptors (SSTR) 1–5 and Therapeutic Implications in Neuroendocrine and Non‐Neuroendocrine Malignancies

International Journal of Cancer, EarlyView.
ABSTRACT Somatostatin receptors (SSTR) mediate the antiproliferative, antisecretory, and proapoptotic effects of somatostatin and its synthetic analogs. Their surface expression on neuroendocrine tumor (NET) cells is required for somatostatin analog therapy and radiopharmaceutical therapy (RPT).

Evaluation of Mutation Risk Using Patient‐Derived Organoids in Patients With Lynch Syndrome

International Journal of Cancer, EarlyView.
ABSTRACT Lynch syndrome (LS) is a hereditary cancer predisposition syndrome caused by germline mutation of DNA mismatch repair (MMR) genes, most notably associated with colorectal cancer. Although LS patients face high risk of CRC, risk can vary even among those with the same pathogenic MMR germline mutations. We suggest a functional assay platform for

DNA Methylation and Transcriptomic Profiles of Wilms Tumour Reveal New Deregulated Genes and Epigenetic Processes Relevant for Tumour Stratification and Management

International Journal of Cancer, EarlyView.
ABSTRACT Wilms Tumour (WT), the most common kidney cancer in children, presents features of altered kidney development and frequently exhibits molecular alterations at the 11p15.5 imprinted locus, affecting the IGF2 and H19 genes, which contribute to tumour growth and predisposition.

Two Steps Methylation Specific PCR for Assessment of APC Promoter Methylation in Gastric Adenocarcinoma [PDF]

Journal of Sciences, Islamic Republic of Iran, 2011
Gastric Cancer (GC) is the second most common cancer in the world and a leading cause of cancer-related mortality. Methylation of promoter CpG islands (CGIs) belonging to tumor suppressor genes causes transcriptional silencing of their corresponding ...

Cross‐Regulation Between DNA Methylation and Circadian Clock Reprogramming in Ovarian Cancer: Mechanistic Insights, Biomarker Potential, and Therapeutic Implications

International Journal of Cancer, EarlyView.
ABSTRACT Early diagnosis remains challenging, recurrence rates remain high, and platinum resistance frequently develops in ovarian cancer (OC), collectively representing major barriers to long‐term patient survival. DNA methylation (DNAm), as a relatively stable yet dynamically modifiable epigenetic signature, can capture alterations in tumor states ...

Maternal overweight and obesity during pregnancy and sex‐dependent dysregulation of the materno‐fetal stress axis

International Journal of Gynecology &Obstetrics, EarlyView.
Abstract Objective Maternal obesity and excess gestational weight gain (GWG) are linked to adverse perinatal outcomes, potentially via disruption of the maternal–fetal stress axis. Placental HSD11B2 protects the fetus from excess glucocorticoids and may influence fetal programming during maternal metabolic stress.

Harnessing microbial metabolism and nutrition to target the gut–mammary axis for better livestock production and health

iMetaOmics, EarlyView.
The gut–mammary axis integrates intestinal health with mammary function through neural, endocrine, and immune pathways. Nutritional interventions (probiotics, prebiotics, metabolites) improve gut microecology, generating microbial signals that travel via the axis to the mammary gland. There, they relieve inflammation, enhance milk quality and lactation,
