ABSTRACT Tumor immune escape is a major barrier to durable cancer immunotherapy, as advanced malignancies create a tumor microenvironment (TME) that preferentially exhausts and disables T cell responses. While most approved cell therapies are T cell‐based, this limitation motivates the exploration of an alternative effector cell platform.

Human Telomerase Activation Requires Two Independent Interactions between Telomerase RNA and Telomerase Reverse Transcriptase [PDF]
Inhibition or activation of the reverse transcriptase telomerase can profoundly affect the proliferative capacity of normal cells and cancers. Here, we elucidate structural requirements for function of the essential RNA component of human telomerase, hTR.

The association between telomerase activity and expression of its RNA component (hTR) in breast cancer patients: the importance of DNase treatment [PDF]
Telomerase is a ribonucleoprotein enzyme that compensates for the telomere length shortening which occurs during the cell cycle. Telomerase activity has been detected in most tumours but not in somatic cells.

Telomeres in Evolution and Development from Biosemiotic Perspective [PDF]
Telomeres identify natural chromosome ends being different from broken DNA through differences in their "molecular syntax" (M.Eigen) which determines the functions of reverse transcriptase and its integrated RNA template, telomerase.

Using a 3D cell culture model of the fibrotic barrier in pancreatic cancer, this work shows that inhibiting NUAK2 kinase in pancreatic stellate cells enhances macromolecular drug delivery. Mechanistically, NUAK2 inhibition disrupted actin stress fiber assembly to downregulate collagen I expression, thus enhancing macromolecular permeability.

The Status of Telomerase Enzyme Activity in Benign and Malignant Gynaecologic Pathologies
Background: Telomeres are essential for the function and stability of eukaryotic chromosomes. Telomerase consists of three subunits: human telomerase reverse transcriptase (hTERT), human telomerase RNA (hTR), and telomerase protein 1 (TP1).

Alternatively Spliced Telomerase Reverse Transcriptase Variants Lacking Telomerase Activity Stimulate Cell Proliferation [PDF]
Eight human and six chicken novel alternatively spliced (AS) variants of telomerase reverse transcriptase (TERT) were identified, including a human variant (Δ4-13) containing an in-frame deletion which removed exons 4 through 13, encoding the catalytic domain of telomerase.

A bioinspired triphasic scaffold integrating 3D printed polycaprolactone and electrospun poly(lactic‐co‐glycolic acid) is developed to replicate the organization of the tendon‐to‐bone enthesis. Cyclic mechanical stimulation induces spatially defined cell morphology and lineage‐related gene expression in human mesenchymal stem cells, highlighting the ...

CHIP Promotes Human Telomerase Reverse Transcriptase Degradation and Negatively Regulates Telomerase Activity [PDF]
The maintenance of eukaryotic telomeres requires telomerase, which is minimally composed of a telomerase reverse transcriptase (TERT) and an associated RNA component. Telomerase activity is tightly regulated by expression of human (h) TERT at both the transcriptional and post-translational levels.

Objective Dermal systemic sclerosis (SSc) fibroblasts and their exosomes can activate keratinocytes in SSc, with long noncoding RNA (lncRNA) H19 highlighted as the most up‐regulated RNA in their cargo compared with healthy controls (HCs). The role of H19 in SSc pathogenesis has never been investigated.
