In this study, researchers used in silico mutagenesis to identify key calcium-binding sites influencing the stability of Rand protease from Bacillus subtilis, potentially enhancing its application in industries like leather dehairing by improving stability and eliminating the need for additional metal ions during the process.

ROS may affect hair loss related to hormones.

In this study of mouse hair follicles, Raptor was specifically expressed in hair follicle stem cells, while Rictor was mainly found in inner root sheath cells, indicating distinct roles in hair growth stages.

The researchers reported two brothers with a new variant of X-linked trichothiodystrophy associated with an RNF113A gene mutation, highlighting features such as intellectual disability and growth failure, but without previously reported endocrinological or genital abnormalities, underlining the importance of genetic counseling for such variants.

In this study, rapamycin was found to increase hair follicle pigmentation and prolong anagen duration in cultured human scalp hair follicles, suggesting it could be explored as an anti-greying agent.

In this study, researchers found that selectively disabling ribonucleotide excision repair in mouse epidermis caused DNA damage, skin inflammation, and led to skin cancer, suggesting a potential role for this repair mechanism in tumorigenesis.

This research suggests that the barley protein RACB supports cell polarity functions rather than interfering with immunity, as it aids nucleus positioning during fungal attack rather than affecting early immune responses.

In this study, Trf1 genetic deletion in mice, including those with cancer-prone mutations, was shown to not affect overall viability and cause only mild effects, while being necessary for tumor formation, suggesting a potential therapeutic window for Trf1 as an anti-cancer target.

This study identified the genes for pyochelin siderophore biosynthesis as a novel target regulated by the heme-responsive PrrH sRNA in Pseudomonas aeruginosa.

In this study, the researchers identified a temperature-sensitive mutant in Arabidopsis thaliana, showing disrupted root hair formation and altered responses to plant hormone treatments at elevated temperatures.

In this study, researchers created a core-shell nanozyme, CeO2@ZIF-8/Au, which autonomously regulates ROS levels to efficiently eliminate bacteria, reduce inflammation, and promote wound healing by balancing ROS generation and scavenging in response to environmental conditions.

This case report highlights that a patient with resistance to thyroid hormone was misdiagnosed as having Graves’ disease, leading to unnecessary radioactive iodine treatment.

This study found that RXRα plays a critical role in hair cycling and keratinocyte functions in mice, likely through its interaction with VDR in epidermal cells.

This study found that D'orenone blocks root hair growth by increasing PIN2 protein abundance, leading to reduced auxin concentration, but external auxin can reverse these effects.

This study suggests that RORα, RORβ, and RORγ mRNA expression in cashmere goat skin is related to different stages of hair follicle development, indicating a possible role in cycled cashmere growth.

In this study using Angora rabbits, researchers found that the FRZB gene inhibits hair follicle development by modulating the Wnt/β-catenin signaling pathway, affecting the expression of various genes related to this pathway and altering cell proliferation and apoptosis.

In this study, the authors found that targeting mTORC1 with rapamycin inhibited TPA-induced skin tumor promotion by affecting keratinocyte proliferation, including critical stem cell populations in the mouse epidermis.

In this study, researchers found that the cell surface protein Lrig1 plays a crucial role in regulating the suppressive function of regulatory T cells, suggesting it as a potential target for treating autoimmune diseases, as evidenced by experiments in mouse models.

Ducks can get the Rous sarcoma virus if infected shortly after birth, leading to tumors and disease spread.

This review highlights REV7's crucial roles in maintaining genome stability, its implication in several cancers, and its association with poor prognoses and treatment resistance, while also noting that REV7 suppression may improve chemotherapy sensitivity.

This study identifies iRhom2 as a crucial regulator of hair follicle differentiation, showing that the iRhom2Uncv mutation leads to dysplasia and reduced TACE maturation, resulting in a hairless phenotype in mice.

This commentary discusses the crucial role of the alternative splicing factor Esrp1 in maintaining skin barrier function and its association with skin diseases like atopic dermatitis and psoriasis, but reports no new clinical results.

This study found that RSPO1 mutations in patients with a 46XX disorder of sexual development contribute to impaired skin integrity and increased risk of squamous cell carcinoma in areas subject to friction.

This study reported that the PrrH sRNA in *Pseudomonas aeruginosa* may directly regulate genes involved in pyochelin siderophore biosynthesis, highlighting its role in adapting to heme availability, with light conditions influencing this gene expression.

Auxin promotes root hair growth through oxidative processes involving reactive oxygen species.

This clinical letter identifies Rothmund-Thomson syndrome type 2 as a rare cause of chronic wounds, but provides no new experimental findings.

In this study, researchers using a Treg-specific HuR-deficient mouse model found that the RNA-binding protein HuR is crucial for stabilizing Foxp3 mRNA, affecting Treg function and immune regulation, with HuR disruption leading to impaired Foxp3 expression and potential autoimmune dysfunction.
