Oocyte–cumulus cell interaction: a key factor in early embryo development

Biological Reviews, EarlyView.
ABSTRACT The evaluation of oocyte competence is a fundamental step in achieving successful outcomes following assisted reproduction techniques (ART). At present, however, conventional oocyte maturation assessment is carried out by morphological observation, which is a subjective method that does not consider molecular features.

Tumor-Specific Expression Detected with the Use of an Expression Vector Driven by Human Telomerase Reverse Transcriptase Gene Promoter

, 2004
To construct the tumor-specific expression vector driven by human telomerase reserve transcriptase gene promoter, we amplified a fragment of the enhanced green fluorescent protein (EGFP) gene from the pEGFP-N 1 plasmid and cloned it into the multiple ...

A Mutant of Tetrahymena Telomerase Reverse Transcriptase with Increased Processivity [PDF]

Journal of Biological Chemistry, 2000
The protein catalytic subunit of telomerase (TERT) is a reverse transcriptase (RT) that utilizes an internal RNA molecule as a template for the extension of chromosomal DNA ends. In all retroviral RTs there is a conserved tyrosine two amino acids preceding the catalytic aspartic acids in motif C, a motif that is critical for catalysis.

Systemic aging fuels heart failure: Molecular mechanisms and therapeutic avenues

ESC Heart Failure, Volume 12, Issue 2, Page 1059-1080, April 2025.
Abstract Systemic aging influences various physiological processes and contributes to structural and functional decline in cardiac tissue. These alterations include an increased incidence of left ventricular hypertrophy, a decline in left ventricular diastolic function, left atrial dilation, atrial fibrillation, myocardial fibrosis and cardiac ...

Multi‐Cohort Analysis Reveals Genetic Predispositions to Clonal Hematopoiesis as Mutation‐Specific Risk Factors for Stroke

Advanced Genetics, Volume 6, Issue 1, March 2025.
This study comprehensively evaluated the differential effect of clonal hematopoiesis (CH) mutations on the risk of various stroke subtypes and functional recovery. It shows that TET2 is associated with small vessel stroke possibly via a pro‐inflammatory pathway. Abstract Recent observational studies have found an association between Clonal Hematopoesis

Human Specific Regulation of the Telomerase Reverse Transcriptase Gene [PDF]

Genes, 2016
Telomerase, regulated primarily by the transcription of its catalytic subunit telomerase reverse transcriptase (TERT), is critical for controlling cell proliferation and tissue homeostasis by maintaining telomere length. Although there is a high conservation between human and mouse TERT genes, the regulation of their transcription is significantly ...

Liquid biopsy in genitourinary oncology: Current clinical applications and future prospects across prostate, bladder, and renal cancers

UroPrecision, EarlyView.
Abstract Liquid biopsy has emerged as a transformative approach in oncology, providing minimally invasive access to tumor‐derived biomarkers with applications across diagnosis, prognosis, therapeutic guidance, and disease monitoring. This literature review synthesizes evidence from 125 studies evaluating circulating tumor DNA, circulating tumor cells ...

Evolving Pathology of Anaplastic Thyroid Carcinoma: Integrating Morphology, Immunohistochemistry, and Molecular Insights

Cancer Science, EarlyView.
Schematic overview of progression from differentiated thyroid carcinoma (DTC) to anaplastic thyroid carcinoma (ATC). ATC primarily develops via two pathways: the BRAF p.V600E‐mutated papillary thyroid carcinoma (PTC) pathway and the RAS‐mutated pathway. The origin and progression of BRAF/RAS‐wildtype ATC remain unclear.

The WHO Classification of Genetic Tumour Syndromes: Considerations for Genetics

Clinical Genetics, EarlyView.
The WHO Classification of Tumours underpins the diagnosis of neoplastic conditions. The new WHO classification of genetic tumour syndromes (GTS) provides international standards for their diagnosis. This diagram highlights the chromosomal distribution of the genes involved in the GTS covered in this classification.
