Paclitaxel induces NM2‐dependent cellular contraction through GEF‐H1 dissociation from microtubules and RhoA/ROCK activation in cancer cells

Molecular Oncology, EarlyView.
Taxanes are widely used chemotherapeutics whose effects on cellular mechanics remain poorly understood. We show that paclitaxel induces rapid cellular contraction by promoting GEF‐H1 dissociation from microtubules and non‐muscle myosin II activation through RhoA/ROCK.

Synergistic Regulation of Pigment Cell Precursors’ Differentiation and Migration by ednrb1a and ednrb2 in Nile Tilapia

Cells
The evolutionary loss of ednrb2 in specific vertebrate lineages, such as mammals and cypriniform fish, raises fundamental questions about its functional necessity and potential redundancy or synergy with paralogous endothelin receptors in pigment cell ...

Radiological Evaluation of Huntington’s Disease: A Case Report [PDF]

Journal of Clinical and Diagnostic Research
Huntington’s Disease (HD) is a rare neurodegenerative condition inherited in an autosomal dominant pattern, where Gamma Amino Butyric Acid-ergic (GABAergic) neurons in the basal ganglia progressively deteriorate.

Optimization of seminal extracellular vesicle isolation protocols for cancer biomarker analysis using proteomic profiling

Molecular Oncology, EarlyView.
This paper shows that size‐exclusion chromatography and sequential centrifugation applied to seminal plasma enrich for different populations of extracellular vesicles. This may significantly affect the detection and analysis of extracellular vesicle‐associated cancer biomarkers.

Dactolisib outperforms Rapamycin in potentiating apoptosis induced by XPO1, Bcl‐2 and Mcl‐1 blockade in preclinical glioblastoma models

FEBS Open Bio, EarlyView.
The PAM pathway and its impact on cellular metabolism. Color‐coded key symbols represent Rapamycin (R, orange, targeting mTOR) and Dactolisib (D, green, targeting PI3K/mTOR), indicating their sites of action. Created with BioRenders.com. Glioblastoma resists therapy through interconnected survival programs.

Novel Fluorescent Guanine Analogs as Guanine deaminase substrates/inhibitors [PDF]

, 2018
TTwo fluorescent guanine analogues (thG, tzG) derived from thieno[3,4-d]-pyrimidine and isothiazole[4,3-d]-pyrimidine, respectively were synthesized and analyzed for their isomorphism and isofunction as the natural occurring guanine.

The intermolecular dimer potential for guanine

The Journal of Chemical Physics, 2017
The ab initio intermolecular potential of guanine has been developed with the help of a combination of symmetry-adapted perturbation theory and density functional theory (DFT). The resulting potential has been globally optimized to locate the guanine cluster structures up to tetramers.

Chronobiology of Cancer: How Aging Fuels Oncogenesis at the Molecular Level

Aging and Cancer, EarlyView.
This graphical abstract illustrates the key biological pathways linking aging with cancer development and progression. In the upper left, cumulative exposure to ultraviolet radiation, toxins, and reactive oxygen species (ROS) causes DNA damage and genomic instability, whereas age‐related decline in repair mechanisms, such as ATM/ATR, BER, and NER ...
