PhysBinder : improving the prediction of transcription factor binding sites by flexible inclusion of biophysical properties [PDF]

, 2013
The most important mechanism in the regulation of transcription is the binding of a transcription factor (TF) to a DNA sequence called the TF binding site (TFBS). Most binding sites are short and degenerate, which makes predictions based on their primary

Redox Regulation and Oxidative Stress in Health and Disease: Mechanisms and Therapeutic Targeting

MedComm – Future Medicine, Volume 5, Issue 2, June 2026.
Reactive species serve crucial roles which are tightly regulated in both physiological as well as disease states. At physiological levels, these species are integral to redox signaling, while uncontrolled redox promotes disease pathology. This review examines the dysregulation of these processes.

Eribulin mesylate targets human telomerase reverse transcriptase in ovarian cancer cells.

PLoS ONE, 2014
Treatment of advanced ovarian cancer involves platinum-based chemotherapy. However, chemoresistance is a major obstacle. Cancer stem cells (CSCs) are thought to be one of the causes of chemoresistance, but the underlying mechanism remains elusive ...

PAX8‐positive conventional urothelial carcinomas of the urinary bladder and their distinct molecular profiles – A clinicopathologic study of 101 consecutive cases with next‐generation sequencing in 20 cases

Histopathology, Volume 88, Issue 7, Page 1315-1323, June 2026.
PAX8 expression in urothelial carcinoma was investigated in 101 consecutive transurethral resections of the urinary bladder. PAX8 was positive in 10% of cases, with targeted molecular testing of these cases revealing universal TERT promoter mutations and frequent alterations in TSC1, NOTCH1 and WT1. Aims PAX8 immunohistochemistry (IHC) is often used to

Lamarck and immunity: Somatic and germline evolution of antibody genes [PDF]

, 2009
Current work on the mechanism of hypermutation of somatically rearranged antibody variable (V) genes shows that the most likely mechanism involves both direct DNA modification (deamination of cytosines to uracils by AID deaminase) and strand nicking plus

The Outcome of Intracellular Selenomonas sputigena and its Impact on Gingival Keratinocytes

Molecular Oral Microbiology, Volume 41, Issue 3, Page 131-144, June 2026.
ABSTRACT Selenomonas sputigena is an understudied oral pathobiont associated with periodontitis and dental caries. We recently demonstrated that S. sputigena binds to gingival epithelial cells (GECs), where afterwards the bacterium causes robust in vitro pro‐inflammatory cytokine production and migration of monocytes and neutrophils.

The differentiation status of primary gonadal germ cell tumors correlates inversely with telomerase activity and the expression level of the gene encoding the catalytic subunit of telomerase

BMC Cancer, 2002
Background The activity of the ribonucleoprotein enzyme telomerase is detectable in germ, stem and tumor cells. One major component of telomerase is human telomerase reverse transcriptase (hTERT), which encodes the catalytic subunit of telomerase.

Characterization of novel alternative splicing sites in human telomerase reverse transcriptase (hTERT): analysis of expression and mutual correlation in mRNA isoforms from normal and tumour tissues [PDF]

, 2006
Background Human telomerase reverse transcriptase (hTERT) is a key component for synthesis and maintenance of telomeres on chromosome ends and is required for the continued proliferation of cells.

Multi‐Omics Signatures of Organ Clocks in Biological Aging and Disease: A Conceptual Framework for Organ‐Specific Aging Clocks

Aging Cell, Volume 25, Issue 5, May 2026.
Organ‐specific aging clocks integrating genomics, epigenomics, transcriptomics, proteomics, and metabolomics offer a more accurate assessment of biological aging than single‐omics approaches. This review proposes a multi‐omics framework emphasizing tissue data, longitudinal study designs, and clinically meaningful training outcomes to advance the ...

Quantification of hTERT Splice Variants in Melanoma by SYBR Green Real-time Polymerase Chain Reaction Indicates a Negative Regulatory Role for the β Deletion Variant

Neoplasia: An International Journal for Oncology Research, 2008
Telomerase activity is primarily determined by transcriptional regulation of the catalytic subunit, human telomerase reverse transcriptase (hTERT). Several mRNA splice variants for hTERT have been identified, but it is not clear if telomerase activity is
