The E‐cadherin‐Wnt‐mir‐994 Axis Repurposes a Cadherin Switch for Niche Robustness and Germline Stem Cell Maintenance

Cell Proliferation, EarlyView.
In the Drosophila ovarian niche, an E‐cadherin‐to‐N‐cadherin switch, mediated by Wnt‐mir‐994 signalling, is repurposed to ensure niche resilience. This compensatory mechanism maintains niche integrity and stem cell support upon E‐cadherin loss, revealing a robustness circuit.

Chromatin Remodeller BRD9 Orchestrates Odontoblastic Differentiation via Coordinating RUNX2‐KLF4

Cell Proliferation, EarlyView.
During odontoblast lineage commitment, the chromatin remodeller BRD9 acts as a critical epigenetic coordinator, orchestrating the chromatin landscape to facilitate synergistic binding of key transcription factors RUNX2 and KLF4 to target loci for odontogenesis.

Mitral regurgitation and decompensated heart failure in a young pregnant pony mare: An aetiological challenge

Equine Veterinary Education, EarlyView.
Summary A 4‐year‐old, 6‐month pregnant, Welsh pony mare presented with severe acute clinical signs including depression, anorexia, pale mucous membranes, tachycardia with a grade 4/6 holosystolic murmur and moderate expiratory dyspnoea with diffuse wheezes. There was no evidence of placentitis or fetal distress.

USING IN VITRO-METHODS FOR PROPAGATION AND PRODUCING SECONDARY METABOLITES FROM EUROPEAN PENNYROYAL PLANTS (MENTHA PULEGIUM L.)

International Journal of Secondary Metabolite, 2016
European pennyroyal (Mentha pulegium L.) is the best source of essential oils and natural antioxidants. The main component of the essential oil is pulegone, which can be a precursor for the synthesis of menthol and menthofuran.The aim of this research is

S‐Adenosylmethionine (SAM) hydrolases counter increased SAM epimerisation in thermophilic archaea

The FEBS Journal, EarlyView.
S‐Adenosyl‐l‐methionine (SAM) is a vital enzyme cofactor. Epimerisation at the sulfonium centre of biologically active (SS,SCα)‐SAM is driven by heat, yielding biologically inactive (RS,SCα)‐SAM. Here, two novel archaeal SAM hydrolases from the thermophilic Sulfolobus acidocaldarius and the halophilic Haloferax volcanii are shown to cleave (RS,SCα)‐SAM.

Inhibition of histone deacetylase in Arabidopsis root calli promotes de novo shoot organogenesis

Frontiers in Plant Science
De novo organogenesis from somatic cells to the entire plant represents a remarkable biological phenomenon, but the underlying regulatory mechanism, particularly at the epigenetic level, remains obscure. In this work, we demonstrate the important role of

From hepatic to hematopoietic: LRH‐1's expanding cellular repertoire to the immune system

The FEBS Journal, EarlyView.
The nuclear receptor LRH‐1 is a well‐characterized regulator of endodermal tissue. Yet, increasing evidence indicates that LRH‐1, although expressed at low levels, is also a critical regulator of the hematopoietic system. LRH‐1 regulates the immune system by contributing to immune cell‐specific functions.

Circadian disruption elicits sex‐specific gut microbiota, endocannabinoidome, and lipid mediator responses

The FEBS Journal, EarlyView.
Circadian disruption via constant light induces sex‐specific remodeling of the microbiome, lipid mediators, and immune responses. Females exhibit broader gut microbiota alterations, reduced jejunal oxylipins, increased hypothalamic N‐acylethanolamines, and a more inflammatory cytokine profile. Muscle responses are sex‐ and fiber type‐dependent: females

Reactivación de rutas ontogénicas en tumores metastásicos: un análisis bioinformático exploratorio

Revista Cubana de Medicina Militar
Introducción: La metástasis representa uno de los procesos más adaptativos y enigmáticos del cáncer. Diversos estudios sugieren que las células tumorales metastásicas podrían reactivar rutas ontogénicas como estrategia de colonización.
