MAPK Inhibitor‐Tolerant Persister Cells in Melanoma: Mechanisms and Therapeutic Vulnerabilities

Cancer Science, EarlyView.
Melanoma response to MAPK inhibition progresses from drug‐sensitive cells to drug‐tolerant persister states, which enable survival through adaptive signaling, metabolic rewiring, and phenotypic plasticity. These persister cells serve as an intermediate reservoir from which resistant tumors ultimately emerge. ABSTRACT Though major advancements have been

Cryo‐EM structures of multiple‐peptide resistance factor (MprF) from Pseudomonas aeruginosa

The FEBS Journal, EarlyView.
Cryo‐EM analysis of MprF from Pseudomonas aeruginosa reveals a dimeric enzyme, distinct from Rhizobium homologues. The soluble GNAT domain contains a dynamic amphipathic helix (TTH) that adopts different positions in detergent micelle and nanodisc, relative to the membrane.

Synthesis and activity of UDP-GlcNAc and UDP-GalNAc analogues

, 2018
UDP-GlcNAc and UDP-GalNAc are the most important Leloir substrates employed by glycosyltransferases (GTs). We are interested in two particular GTs: OGT and GalNAc-T2. The human O-GlcNAc transferase (hOGT) is a metal independent Leloir GT that transfers GlcNAc to Ser or Thr residues of intracellular proteins and peptides. hOGT is an essential enzyme for

Phenotypic characterization of Arabidopsis thaliana mutants that alleviate root growth defects in a vitamin B6 biosynthesis mutant

The FEBS Journal, EarlyView.
Vitamin B6 is a critical molecule for plant metabolism and development. Rsr4‐1, a loss‐of‐function mutant in a vitamin B6 biosynthesis gene, has a distinct short root phenotype. Here we describe five novel suppressor mutants with an rsr4‐1 background that have normalized root growth and distinct phenotypic and molecular characteristics, representing a ...

Transcriptomic and proteomic signatures underlying nymphal adaptation and foam production in the forage pest Mahanarva spectabilis

Insect Molecular Biology, EarlyView.
RNA‐seq and Batelli gland proteomics of fifth‐instar Mahanarva spectabilis nymphs reveal transcripts and proteins associated with xylem feeding, foam production and environmental interaction. Functional annotation identified genes involved in osmoregulation, detoxification, chemosensation and stress responses, while proteomic analysis confirmed ...

Genome assembly of Elcysma westwoodi provides insights into host‐plant cyanogenic glucoside detoxification and chemical defence gene evolution

Insect Molecular Biology, EarlyView.
A chromosome‐level genome of Elcysma westwoodi was assembled. The genome encodes 272 detoxification‐related genes. A single‐copy bCAS was retained for cyanide detoxification. CYP405A and CYP332A were recruited into cyanogenic defence evolution. UGT33A retained a conserved GT‐B fold and catalytic domains.

The multidimensional regulation roles and mechanisms of calcium in fruit quality

Journal of Integrative Plant Biology, EarlyView.
This review explores how calcium signaling molecule integrates plant hormones, environmental cues, and developmental signals to influence external fruit traits, internal nutritional properties, and physiological disorders. ABSTRACT Calcium (Ca2+), a dual‐functional mineral that serves both as an essential structural factor and a signaling molecule ...

Genomic variation drives plant flavor diversification

Journal of Integrative Plant Biology, EarlyView.
This review explains how genomic variation shapes plant flavor by altering the biosynthetic and regulatory pathways of key attributes like sweetness, acidity, bitterness, piquancy, astringency, and aroma. It also discusses how multi‐omics, AI‐assisted breeding, and gene editing can translate this knowledge into plants with improved flavor, nutrition ...
