MLH1 deficiency enhances tumor cell sensitivity to ganciclovir [PDF]

Cancer Gene Therapy, 2009
Suicide gene therapy with herpes simplex virus thymidine kinase (HSV-TK) and ganciclovir (GCV) is notable for producing multi-log cytotoxicity in a unique pattern of delayed cytotoxicity in S-phase. As hydroxyurea, a ribonucleotide reductase inhibitor that activates mismatch repair, can increase sensitivity to GCV, we evaluated the role of MLH1, an ...

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

The Prostate, EarlyView.
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).

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.

Does sex of the patient play a role in survival for MSI colorectal cancer? [PDF]

, 2018
Microsatellite instability (MSI) is a feature of colorectal tumors that develops as a result of inactivation of the DNA mismatch repair system. It is found in about 15% of all colorectal cancers and is an important prognostic molecular marker when ...

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.

Complex-based analysis of dysregulated cellular processes in cancer [PDF]

, 2014
Background: Differential expression analysis of (individual) genes is often used to study their roles in diseases. However, diseases such as cancer are a result of the combined effect of multiple genes.

Mapping the Prevalence of Lynch Syndrome in the Ceará—Northeast of Brazil

Clinical Genetics, EarlyView.
Distribution of pathogenic variants associated with Lynch syndrome across Brazil, with a particular emphasis on the state of Ceará. The illustration highlights the most frequently reported MMR genetic variants in Brazil and provides a magnified view of Ceará, where three novel variants were identified in the APC, SMAD4, and MSH6 genes within specific ...

Computational and cellular studies reveal structural destabilization and degradation of MLH1 variants in Lynch syndrome

eLife, 2019
Defective mismatch repair leads to increased mutation rates, and germline loss-of-function variants in the repair component MLH1 cause the hereditary cancer predisposition disorder known as Lynch syndrome. Early diagnosis is important, but complicated by

SOX30 Governs Synaptonemal Complex Assembly and Homologous Recombination in Male Meiosis

Cell Proliferation, EarlyView.
The transcription factor SOX30 directly binds promoter regions of SYCE1 and SYCE2 to mediate their transcriptional activation, thereby enabling proper assembly of central elements within the synaptonemal complex. Structural destabilisation of the synaptonemal complex in Sox30 KK spermatocytes triggers synaptic discontinuity, impairs homologous ...

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
