Sheep Horn Development Revealed by Multi‐Tissue and Cross‐Species Transcriptomic Analysis

Animal Research and One Health, EarlyView.
Multi‐tissue and cross‐species transcriptomics with allele‐specific expression show sheep horns are a composite organ integrating epidermal and osteogenic programs. Conserved horn gene modules and cis‐regulatory variation fine‐tune expression networks underlying horn development and size (small scurs vs. large spiral horns).

The extension of the taxon cycle model to island plants: insights from the Canarian vascular flora

Biological Reviews, EarlyView.
ABSTRACT Taxon cycle models describe eco‐evolutionary patterns of lineage colonization, diversification, and decline across archipelagos, inferring an important role for competition amongst ecologically similar taxa in driving concurrent niche changes.

Candidate genes for the development of hair follicles in Hu sheep

Genetics and Molecular Research, 2016
The aim of this study was to detect candidate genes for the development of hair follicles in the Hu sheep breed. Seven genes have been detected in large, medium, and small wave follicles of Hu sheep using gene chip technology. The histological features of the follicles of newborn Hu-lambs were combined with fluorescence quantitative PCR technology to ...

Lipid‐based Nano‐delivery systems as a promising strategy for the treatment of epilepsy: Current status and challenges

Epilepsia Open, EarlyView.
Abstract Objective Epilepsy is a prevalent chronic neurological disorder characterized by abnormal neuronal electrical activity. The primary treatment modality for individuals with epilepsy (PWE) is antiseizure medication (ASM). The multiple potential factors contributing to treatment resistance in epilepsy may be attributed to the inability of ASMs to

Hair follicle dermal cells: a morphological, behavioural and molecular study [PDF]

, 1995
Anatomy and smooth muscle a-actin expression in hair follicles from a variety of animal species (Mink, Polecat, Meerkat, Grey squirrel and stoat) was investigated. Smooth muscle ɑ-actin expression was related to follicle activity. Expression was greatest
