Errors in chromosome segregation during oogenesis and early embryogenesis [PDF]

, 2010
Errors in chromosome segregation occurring during human oogenesis and early embryogenesis are very common. Meiotic chromosome development during oogenesis is subdivided into three distinct phases.

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.

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 ...

UBR2 of the N-end rule pathway is required for chromosome stability via histone ubiquitylation in spermatocytes and somatic cells [PDF]

, 2012
The N-end rule pathway is a proteolytic system in which its recognition components (N-recognins) recognize destabilizing N-terminal residues of short-lived proteins as an essential element of specific degrons, called N-degrons.

Risk of Cancer With Hormone Replacement Therapy: A Narrative Review

BJOG: An International Journal of Obstetrics &Gynaecology, EarlyView.
ABSTRACT Hormone replacement therapy (HRT) remains the cornerstone of menopausal symptom management, effectively alleviating vasomotor symptoms and genitourinary syndrome, whilst mitigating long‐term risks such as osteoporosis. However, despite an increasing body of evidence on the relative safety of HRT, earlier studies that demonstrated an increased ...

Correlation of MLH1 and MGMT expression and promoter methylation with genomic instability in patients with thyroid carcinoma [PDF]

, 2013
Background: Gene silencing of the repair genes MLH1 and MGMT was shown to be a mechanism underlying the development of microsatellite instability (MSI), a phenotype frequently associated with various human malignancies.

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 ...

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
