A new Escherichia coli laboratory evolution screen for detecting plant ribulose-1,5-bisphosphate carboxylase/oxygenase (Rubisco) mutations with enhanced CO-fixation capacity has identified substitutions that can enhance plant productivity. Selected were a large subunit catalytic (Met-116-Leu) mutation that increases the k of varying plant Rubiscos by 25% to 40% and a solubility (Ala-242-Val) mutation that improves plant Rubisco biogenesis in E. coli 2- to 10-fold.

Insects, such as , rely on innate immune defences to combat microbial threats. Antimicrobial peptides (AMPs) play an important role in limiting pathogen entry and colonization. Despite intensive research into the regulation and biochemical properties of antimicrobial peptides, their exact significance has remained uncertain due to the challenges of mutating small genes.

Background: Nasopharyngeal carcinoma (NPC) pathogenesis is multi-factorial, involving synergistic interactions among genetic susceptibility, Epstein-Barr virus (EBV) infection, and environmental exposures. Notably, specific multi-generational families exhibit NPC incidence substantially exceeding both sporadic cases and general genetic susceptibility cohorts, demonstrating Mendelian inheritance patterns. This supports the hypothesis that high penetrance pathogenic variants dominate disease initiation and progression in familial NPC.

Methods: For this study, 10 male dogs were enrolled, comprising 4 healthy Beagles and 6 client-owned dogs with suspected prostatic neoplasia. Computed tomography perfusion was performed in the healthy dogs using varied contrast agent doses and injection durations.

The MET receptor tyrosine kinase is a pivotal regulator of cellular survival, motility, and proliferation. Mutations leading to skipping of exon 14 (METΔex14) within the juxtamembrane domain of MET impair receptor degradation and prolong oncogenic signaling, contributing significantly to tumor progression across multiple cancer types. METΔex14 mutations are associated with aggressive clinical behavior, therapeutic resistance, and poor outcomes.
