Unlocking the secret drivers of deadly pancreatic cancer: New target offers hope for treatment

Researchers identify a super-enhancer-regulated RNA-binding protein cascade that drives the growth of pancreatic ductal adenocarcinoma, a deadly form of pancreatic cancer. The discovery offers a promising new avenue for targeted therapy, potentially sidestepping severe side effects associated with other treatments.

New therapy to mitigate fragile X syndrome may be on the horizon

An antisense therapy developed by Joel D. Richter, PhD, Sneha Shah, PhD, and Jonathan K. Watts, PhD, at UMass Chan Medical School and Elizabeth Berry-Kravis, MD, PhD, at RUSH University Medical Center, restores production of the protein FMRP in cell samples taken from patients with fragile X syndrome.

Deciphering a biochemical mechanism explains the center of protein factories

Based on genetic blueprints, individual amino acids are assembled into long amino acid chains, the proteins, in the protein factories of our cells, the ribosomes. Each newly formed protein starts with the amino acid methionine.

Scientists uncover key molecular culprit in ALS: PEG10 gene implicated in pathogenesis

UBQLN2 dysfunction in ALS leads to elevated PEG10 levels, suggesting a role for retrotransposon activity in the disease. PEG10's nuclear localization alters gene expression involved in axon remodeling, implicating it as a contributing mechanism in ALS.

Reviving a forgotten antibiotic: Old drug shows new promise against superbugs

Research discusses the activity spectrum of nourseothricin and its components, S-F and S-D, against drug-resistant, gram-negative pathogens. S-F showed promising activity against NDM-1-expressing Klebsiella pneumoniae Nevada strain with minimal toxicity, and it probes the A-decoding site potentially accounting for its miscoding activity.

Repair crews may move in to help fix the oxidative damage in protein factories

In a discovery fundamental to the inner workings of cells, scientists have discovered that if oxidative stress damages protein factories called ribosomes, repair crews may move in to help fix the damage so work can quickly resume.

Study reveals molecular mechanisms that give bacteria its 'superpowers' against antibiotics

A species of ordinary gut bacteria that we all carry flourishes when the intestinal flora is knocked out by a course of antibiotics. Since the bacteria is naturally resistant to many antibiotics, it causes problems, particularly in healthcare settings.
