The adhesion GPCRs CELSR1-3 and LPHN3 engage G proteins via distinct activation mechanisms

This study investigates how different adhesion GPCRs, CELSR1-3 and LPHN3, engage G proteins through distinct activation mechanisms, revealing that cleavage is not universal among aGPCRs.

MicroRNAs contribute to the host response to Coxiella burnetii

This study identifies miRNA changes in C. burnetii-infected macrophages and shows miR-143-3p down-regulation promotes pathogen growth by reducing apoptosis and autophagy.

Glucagon-Like Peptide-1 Receptor Activation Stimulates PKA-Mediated Phosphorylation of Raptor and this Contributes to the Weight Loss Effects of Liraglutide

This study shows that GLP-1R agonist liraglutide induces PKA-mediated phosphorylation of Raptor at Ser791, which contributes to its weight loss effect.

Genome-wide identification of novel sRNAs in Streptococcus mutans

This study identifies 15 novel sRNAs in Streptococcus mutans that respond to stress conditions and shows one sRNA, SmsR4, regulates sorbitol transport.

A peroxide-responding sRNA evolved from a peroxidase mRNA

The paper identifies a novel origin of sRNAs from protein-coding genes, demonstrating how OxyS evolved from a peroxidase mRNA fragment and remains part of the original regulon.

Captivity-induced behaviour and spatial learning abilities in an enigmatic, aquifer-dwelling blind eel, Rakthamichthys digressus

This study examines how captivity affects behavior and spatial learning in the blind eel Rakthamichthys digressus, finding altered behaviors but no change in behavioral syndromes or spatial learning ability.

Ticks convert pathogenic Coxiella into endosymbionts

This study sequenced a Coxiella-like endosymbiont from ticks and compared it to other Coxiellaceae, revealing evolutionary relationships and identifying metabolic pathways critical for pathogenicity.

Novel small RNAs expressed by Bartonella bacilliformis under multiple conditions reveal potential mechanisms for persistence in the sand fly vector and human host

This study identifies 160 small RNAs in Bartonella bacilliformis under various environmental conditions, revealing potential mechanisms for its persistence in sand flies and human hosts.

The identity and distribution of Bhavania annandalei Hora 1920 (Cypriniformes: Balitoridae), a hillstream loach endemic to the Western Ghats of India

The paper resurrects Bhavania annandalei as a distinct species from B. australis using morphological, morphometric, meristic, and genetic data.

Big fish in small tanks: Stunting in the Deccan Mahseer, Tor khudree (Sykes 1849)

The study documents stunting in the Deccan mahseer under high-density lab conditions and discusses conservation and aquaculture implications.

Coxiella burnetii small RNA 12 binds CsrA regulatory protein and transcripts for the CvpD type IV effector, regulates pyrimidine and methionine metabolism, and is necessary for optimal intracellular growth and vacuole formation during infection

This study identifies CbsR12, a small RNA in Coxiella burnetii, which binds CsrA and regulates metabolic genes and a type IV effector, essential for intracellular growth and vacuole formation.
