Evidence That the Protein Phosphatase Activity of PTEN Contributes to Embryonic Development and Tumor Suppression

Cancer Science, EarlyView.
Mice expressing only mutant PTEN Y138L, a protein which shows normal suppression of cellular AKT yet lacks protein phosphatase activity, die in utero, and heterozygous mice display a range of tumors. This indicates both the lipid and protein phosphatase activities of PTEN work together for normal tumor suppression and embryonic development.

RuvB12 as a regulator of hTERT

, 2010
Telomere maintenance is essential for the continued proliferation of tumour cells and is performed through the mechanism of telomerase activation or by a recombination-based process referred to as alternative lengthening of telomeres (ALT). The most important components of active telomerase are the reverse transcriptase enzyme (hTERT) and the non ...

Pleiotropic Roles of FBXO11 in Tumorigenesis: Implications for Targeted Therapy

Cancer Science, EarlyView.
This complex comprises of scaffold CUL1, SKP1, RBX1 and FBXO11 receptor. The substrate is phosphorylated by specific kinase enzyme and recognized by the substrate recognition domain. FBXO11 targets numerous substrates for ubiquitination and degradation, FBXO11 substrates mainly include Snail, ZEB1, p53, BCL6, CDT2, CIITA, Cdc25a, hnRNPA2B1, SAMD1 and ...

Interaction studies of carbon nanomaterials and plasma activated carbon nanomaterials solution with telomere binding protein

Scientific Reports, 2017
Most cancer cells have telomerase activity because they can express the human telomerase reverse transcriptase (hTERT) gene. Therefore, the inhibition of the hTERT expression can play an important role in controlling cancer cell proliferation.

Evaluating EndoC βH5 pseudoislets as a model for human islet transplantation

Diabetic Medicine, EarlyView.
Abstract Aims The EndoC βH5 cell line represents a promising human β‐cell model for preclinical diabetes research. Indeed, EndoC βH5 cells aggregate into islet‐like organoids, secrete insulin in a glucose‐dependent manner, and express a variety of β‐cell functional markers.

The H19/miR‐760/BST2 regulatory axis sustains breast cancer tumorigenesis and metastasis

The FEBS Journal, EarlyView.
H19 and BST2 promote breast cancer aggressiveness through their reciprocal coregulation by miR‐760. Since both transcripts are targeted by miR‐760, overexpression of one sequesters the microRNA and relieves repression of the other: H19 raises BST2 levels, and BST2 raises H19 levels.

Diverse regulatory manners of human telomerase reverse transcriptase

Cell Communication and Signaling, 2019
Human telomerase reverse transcriptase (hTERT) is the core subunit of human telomerase and plays important roles in human cancers. Aberrant expression of hTERT is closely associated with tumorigenesis, cancer cell stemness maintaining, cell proliferation,

Bakuchiol: From structural mimicry to systems‐level skin biology

International Journal of Cosmetic Science, EarlyView.
Convergent outcomes, divergent mechanisms: bakuchiol vs. retinol. Bakuchiol exhibits functional convergence with retinol in improving extracellular matrix integrity, epidermal differentiation and barrier function, while operating through distinct mechanisms.

Receptor C_k-dependent signaling regulates hTERT gene transcription

BMC Cell Biology, 2006
Background Available evidence suggests that the regulation of telomerase activity primarily depends on the transcriptional control of the human telomerase reverse transcriptase (hTERT) gene.

Pretreatment of keratinocytes with Galactomyces ferment filtrate (GFF) promotes stress resiliency in an in vitro oxidative stress model

International Journal of Cosmetic Science, EarlyView.
GFF pretreatment enhances keratinocyte protection against oxidative stress by mitigating stress‐induced biomolecular changes and gene expression dysregulation. GFF‐pretreated keratinocytes maintain healthy epidermal biology post‐stress, preserving mitochondrial function and proliferative capacity.
