From Lab Bench to Bedside: The Potential of Renewable Polymers to Revolutionize Medicine

Scienmag

Preclinical in vitro and in vivo studies must demonstrate biocompatibility, absence of genotoxicity, and predictable degradation profiles. Despite these promising qualities, clinical translation demands rigorous validation of the polymers’ safety and efficacy.

Unraveling Cytarabine’s Neurotoxic Mechanism

Scienmag

Many of these genes orchestrate the delicate coordination of movement and motor control, elucidating how cytarabine’s genotoxic stress translates into cerebellar dysfunction and motor deficits. Another striking facet of this research lies in the differential neurotoxic profiles among various cytidine analogues.

Cx43 Boosts BRAF/MEK Inhibitor Effect via DNA Repair Reduction

Scienmag

Mechanistically, this study shows that Cx43 expression correlates with impaired homologous recombination (HR) repair pathways, the very systems cancer cells rely on to mend double-strand breaks induced by genotoxic stress or therapeutic agents.

UT Health San Antonio Scientists Uncover Key Mechanisms Behind Cancer Drug Resistance

Scienmag

The integrity of DNA repair pathways is fundamental to cellular survival, particularly under the assault of genotoxic agents. The CST complex, composed of the proteins CTC1, STN1, and TEN1, is recognized as a vital regulator of DNA break repair, orchestrating pathway choice via blockade of DNA end resection.

Antihypertensives and Kidney Cancer Risk Linked

Scienmag

Hypotheses include drug-induced alterations in renal hemodynamics, direct genotoxic effects, or modulation of cellular pathways involved in tumorigenesis. The study also calls for further mechanistic investigations to unravel the biological pathways through which these medications might promote carcinogenesis in renal tissue.

How Cigarette Smoke and DNA Repair Deficiency Collaborate to Drive Lung Cancer Development

Scienmag

This consistent pattern of decreased DNA repair capacity suggests a compromised ability to cope with ongoing genotoxic stress in the pre-cancerous microenvironment. In both unmatched and patient-matched comparisons, malignant lung tissue exhibited marked reductions in XPC transcript abundance relative to adjacent benign lung.
