Gabapentin reduces nausea caused by GLP-1 drugs in both FDA database analysis and mouse experiments

FAERS analysis: gabapentin and acetaminophen significantly lowered nausea events in GLP-1-treated patients. Mouse validation: exenatide induced dose-dependent pica (nausea); gabapentin co-treatment significantly decreased exenatide-induced pica without affecting food intake.

Human defensin HD5 shapes infant gut microbiome by promoting Bifidobacterium colonization during weaning

HD5 secretion positively correlated with Bifidobacterium abundance during weaning. High weaning-period Bifidobacterium predicted Bifidobacterium-rich microbiota at age 3. HD5 selectively kills pathogens while sparing beneficial bacteria like Bifidobacterium.

Meta-analysis: SGLT2 inhibitors outperform GLP-1 drugs for heart failure and kidney protection in diabetes

NMA: SGLT2i reduced HF hospitalization and kidney outcomes more than incretin therapies in T2D+ASCVD/high CV risk and CKD. Incretin therapies uniquely reduced HF events in HFpEF with obesity. Both classes reduced MACE, CV mortality, all-cause mortality, MI, and stroke in T2D+ASCVD. SGLT2i benefits extended to acute HF and post-MI.

Proline-rich antimicrobial peptides inhibit bacterial protein synthesis through two distinct ribosome-binding mechanisms

Two classes of PrAMP mechanisms identified: Class I blocks elongation (A-site tRNA interference, P-site CCA-end disruption), Class II disrupts termination, ribosome release, and 50S assembly. New rumidicin family with Trp-Phe dyad enhances activity. Multiple binding sites on ribosomes for Class II.

Tumor-homing peptides guide nanoparticles to cancer cells for targeted drug delivery with fewer side effects

Tumor-homing peptides target receptors on tumor vasculature for selective NP delivery. Tumor-penetrating peptides promote extravasation and deep tissue penetration. Peptide targeting exploits molecular differences between healthy and malignant tissue. Review covers accumulation, barrier overcoming, and therapeutic outcomes.
