Four-way regulation of mosquito yolk protein precursor genes by juvenile hormone-, ecdysone-, nutrient-, and insulin-like peptide signaling pathways. [PDF]

open access: yes, 2014
Anautogenous mosquito females require a meal of vertebrate blood in order to initiate the production of yolk protein precursors by the fat body. Yolk protein precursor gene expression is tightly repressed in a state-of-arrest before blood meal-related ...

Gastrula‐Premarked Posterior Enhancer Primes Posterior Tissue Development Through Cross‐Talk with TGF‐β Signaling Pathway

open access: yesAdvanced Science, EarlyView.
A gastrula‐premarked enhancer within the first intron of Cdx2 governs posterior embryonic development via both regulating Cdx2 expression in cis and coordinating TGF‐β signaling in trans to ensure proper posterior body development. Functional rescue in gastruloids reveals a Cdx2‐independent pathway, highlighting p‐Enh‐eRNA as key epigenetic ...

Molecular evolution of candidate male reproductive genes in the brown algal model Ectocarpus [PDF]

open access: yes, 2016
Background: Evolutionary studies of genes that mediate recognition between sperm and egg contribute to our understanding of reproductive isolation and speciation. Surface receptors involved in fertilization are targets of sexual selection, reinforcement,

NDRG1‐Driven Lactate Accumulation Promotes Lung Adenocarcinoma Progression Through the Induction of an Immunosuppressive Microenvironment

open access: yesAdvanced Science, EarlyView.
NDRG1 drives lactate accumulation and histone lactylation in lung adenocarcinoma, promoting immunosuppression via M2 macrophage polarization and CD8⁺ T cell inhibition. High NDRG1 expression correlates with poor prognosis, an immunosuppressive microenvironment, and immunotherapy resistance.

Gasdermin D‐Mediated Pyroptosis Exerts Two Opposite Effects of Resisting Enzymatic Digestion and Expanding Inflammatory Response in Acute Pancreatitis

open access: yesAdvanced Science, EarlyView.
Gasdermin D (GSDMD) does not only reduce pancreatic enzyme synthesis but also induces pancreatic acinar cells to express mucin 1 (MUC1), which forms a barrier to prevent digestive enzyme‐mediated digestion. However, GSDMD can promote the secretion of inflammatory cytokines by macrophages and aggravate pancreatic histological injury by expanding ...

Changes in Serum Protein Profile in Laying Hens Housed in a Cage-Free System

open access: yesVeterinary Medicine International
The objective of this study was to characterize the distribution of serum proteins in laying hens reared under cage-free open farm conditions and to evaluate the changes in the concentrations of serum protein fractions throughout the 1-year laying period.

Regenerative Hair Pigmentation via Skin Organoids: Adaptive Patterning Mediated by Collagen VI and Semaphorin 3C

open access: yesAdvanced Science, EarlyView.
The release of COL6A3 by fibroblasts is sensed by the CD44 receptor on melanocytes, activating glutathione (GSH) metabolism and increasing melanocyte survival during skin organoid culture. SEMA3C released by bulge cells binds to the NRP1 receptor on melanocytes, regulating microtubule stability and promoting melanocyte recruitment and function during ...
