This study identified a primitive coarse wool characteristic in Merino sheep that enhances environmental adaptability and fine wool yield without reducing quality, suggesting that epigenetic mechanisms, particularly involving the imprinted Gtl2-miRNAs locus, regulate this advantageous trait.

In this study, researchers conducted whole-genome resequencing of eight sheep breeds to identify additional genes associated with wool fineness, revealing 269 genes in fine wool and 319 in coarse wool breeds that are linked to significant traits and pathways.

This review discusses the roles of hypoxia and epigenetics in cellular reprogramming and their contributions to tissue regeneration, reporting no new experimental results.

This review reports that transcriptional and epigenetic mechanisms in epithelial stem cells guide their fate in the epidermis and hair follicles, crucial for skin homeostasis, but disruptions can lead to disease.

This review compiles current research on the role of long non-coding RNAs in regulating muscle growth and regeneration processes, particularly their influence on Duchenne muscular dystrophy, and reports no new clinical results.

In this study, researchers found that the transcriptional program regulated by PRC2 is not necessary for maintaining hair follicle stem cell quiescence and hair regeneration in vivo.

This study found that PRC2 plays a non-instructive role in adult hair follicle stem cells, with its loss not affecting quiescence or cell identity, despite upregulation of genes linked to activation.

This study found that Sonic hedgehog signaling is crucial for Merkel cell development around hair follicles in mice, with Polycomb repressive complex 2 loss causing ectopic Merkel cells across all hair types.

This study found that Polycomb repressive complex 1 is crucial for skin development and stem cell specification, influencing gene activity beyond its known repressor functions.

This study found that Polycomb Repressive Complex 1 is crucial for maintaining stem cell identity across different lineages, but its loss results in varied transcriptional outcomes depending on the tissue context.

This study suggests that hair loss disorders like Marie Unna hereditary hypotrichosis may result from mutations that disrupt post-transcriptional regulation of HR protein expression by PCPB2 interacting with Hr mRNA.

This study suggests that PrPC plays a role in the differentiation of mouse embryonic stem cells during neurogenesis, impacting neural progenitor cell development.

This study suggests that Ptprq in the hair bundles may exist as multiple isoforms that are differentially expressed throughout development and affect the organization of stereocilia in the chick inner ear.

This study reports the first cases of recessive KRT17-related pachyonychia congenita involving all ectodermal derivatives in seven members of two consanguineous Pakistani families.

This study suggests that KRTAP2-3 may serve as a novel biomarker to identify cells in the polyaneuploid cancer cell state, which is linked to therapy resistance and poor prognosis in prostate cancer.

This study describes GPRC5D's unique expression pattern in tissues that produce hard keratin, with retinoic acid inducing its expression in hair bulb cells and affecting keratin gene regulation.

This study found that Celsr1, not Celsr2, is the primary protein involved in establishing planar cell polarity and hair follicle polarization in the epidermis of mice.

This study found that RALF peptides, through liquid-liquid phase separation, form condensates with pectin and other proteins, playing a pivotal role in plant development and stress response regulation.

This review discusses the evolution of platelet concentrates in regenerative medicine, highlighting a proposed function-driven classification that distinguishes three generations of PCs by biological activity rather than development order, with third-generation exosome-based therapies showing superior therapeutic efficacy over earlier formulations.

This study found that PRX102, a peroxidase with a unique polar localization pattern, plays a role in root hair growth by aiding the transport of materials to the tips of growing root hairs.

In this study, researchers found that overexpression of CRABP2 enhanced the proliferation of dermal papilla cells in Hu sheep through activation of the Wnt/β-catenin pathway, even when the pathway was inhibited.

This study identified a high-risk allele in the PLCD1 gene associated with hereditary trichilemmal cyst formation, proposing a monoallelic two-hit mechanism as the underlying genetic pathogenesis.

This article reviews the use of platelet rich plasma in regenerative medicine and highlights the need for standardization in its preparation and application, reporting no new clinical results.

This study found that mrp/plf-mRNA expression in murine skin increases in response to different tumor promoters, suggesting its potential as a short-term biomarker for chemical carcinogenesis.

The researchers reported that disrupting the RPGRIP1L gene in mice impaired desmosome function, causing skin blistering, and their findings suggest that PKCβII inhibition could help treat pemphigus.

This study utilized a sequence-structure alignment approach to improve the characterization of Class A Rhodopsin GPCR superfamily, including orphan and unclassified receptors, through evolutionary analysis.

This study found that FDA-cleared devices for preparing platelet-rich plasma showed inconsistent product quality, with variable platelet counts and inadequate quality control performance, suggesting clinical improvement may not rely on platelet concentration.

This study found that adding PRP to DPCP treatment for severe alopecia areata did not enhance effectiveness compared to DPCP alone.

Platelet Rich Plasma (PRP) shows promise for tissue repair and immune response, but more research is needed to fully understand it and optimize its use.

This study found that the PLC2 gene plays a critical role in auxin-mediated root development in Arabidopsis, influencing root growth and PIN2 distribution.
