The phosphatidylinositol 3-kinase (PI3K)/AKT/mTOR signaling pathway is critical for cellular growth and metabolism. Recently, mosaic or segmental overgrowth, a clinical condition caused by heterozygous somatic activating mutations in PIK3CA, was established as PIK3CA-related overgrowth spectrum (PROS). In this study, we report a Japanese female diagnosed with PROS, who presented with hyperplasia of the lower extremities, macrodactyly, multiple lipomatosis, and sparse hair. Sequencing and mutant allele frequency analysis of PIK3CA from affected tissues revealed that the patient had a heterozygous mosaic mutation (c...

Hair testing is a powerful tool routinely used for the detection of drugs of abuse. The analysis of hair is highly advantageous as it can provide prolonged drug detectability versus that in biological fluids and chronological information about drug intake based on the average growth of hair. However, current methodology requires large amounts of hair samples and involves complex time-consuming sample preparation followed by gas or liquid chromatography coupled with mass spectrometry. Mass spectrometry imaging is increasingly being used for the analysis of single hair samples, as it provides more accurate and visual chronological information in single hair samples...

The epidermis consists of several distinct compartments including the interfollicular epidermis (IFE), sweat glands, sebaceous glands (SGs), and the hair follicle (HF). While the IFE and SGs are in a constant state of self-renewal, the HF cycles between phases of growth, destruction, and rest. The hair follicle stem cells (HFSCs) that fuel this perpetual cycle have been well described and are located in a niche termed the bulge. These bulge SCs express markers such as CD34 and Keratin 15 (K15), enabling the isolation of these cells...

This study was conducted in order to evaluate the role of low-level laser treatment (LLLT) in hair growth in C3H/HeJ mice. Healthy C57BL/6 mice were randomly divided into two groups: with and without low-level laser treatment. The skin color of each mouse was observed each day. Skin samples were collected for H&E, immunofluorescence, PCR, and western blot analysis, to observe the morphology of hair follicles and detect the expression levels of Wnt10b and β-catenin. Observation of skin color demonstrated that black pigmentation started significantly earlier in the laser group than in the control group...

Seasonal coat colour change is an important adaptation to seasonally changing environments but the evolution of this and other circannual traits remains poorly understood. In this study we use gene expression to understand seasonal coat colour moulting in wild snowshoe hares (Lepus americanus). We used hair colour to follow the progression of the moult, simultaneously sampling skin from three moulting stages in hares collected during the peak of the spring moult from white winter to brown summer pelage. Using RNA-sequencing, we tested if patterns of expression were consistent with predictions based on the established phases of the hair growth cycle...

Hirsutism is defined as excessive terminal hair growth in a male pattern in females. It typically affects 5 to 10% of reproductive-age women. Excessive hair growth can often cause significant psychological and emotional distress. As a result, hirsutism is a common presenting complaint to healthcare professionals, including dermatologists, as women search for cosmetic and medical solutions to their problem. Hirsutism results from excess production of androgens, often from ovarian or adrenal sources. It is typically associated with a metabolic syndrome like polycystic ovarian syndrome (PCOS), but can be idiopathic or medication-induced...

The molecular genetic program for root hair development has been intensively studied in Arabidopsis. To understand the extent to which this program might operate in other plants, we conducted a large-scale comparative analysis of root hair development genes from diverse vascular plants, including eudicots, monocots, and a lycophyte. Combining phylogenetics and transcriptomics, we discovered conservation of a core set of root hair genes across all vascular plants, which may derive from an ancient program for unidirectional cell growth coopted for root hair development during vascular plant evolution...

Root hair growth dramatically expands the root surface area, thus facilitating water and nutrient uptake. Until recently, the molecular mechanism underlying root hair growth was unknown. Recent studies have revealed that the transcription factor ROOT HAIR DEFECTIVE 6 LIKE 4 (RSL4) coordinates hormonal, environmental, and developmental factors to trigger polar growth.

Targeted phototherapy and multi-modal imaging can effectively improve the therapeutic efficacy and reduce the side effects of theranostics. Herein, we constructed novel biocompatible cyanine dye IR808-conjugated hyaluronic acid nanoparticles (HAIR NPs) for photothermal therapy (PTT) with near-infrared fluorescence (FL) and photoacoustic (PA) dual-modal imaging. The nanoparticles formed stable nanostructures under aqueous conditions with uniform size distribution. The HAIR NPs were rapidly taken up by the human lung cancer cells A549 via CD44 (the hyaluronic acid receptor on the surface of tumor cells) receptor-mediated endocytosis...

As the world population increases, strategies for sustainable agriculture are needed to fulfill the global need for plants for food and other commercial products. Nanoparticle formulations are likely to be part of the developing strategies. CuO and ZnO nanoparticles (NPs) offer potential as fertilizers, as they provide bioavailable essential metals, and as pesticides, because of dose-dependent toxicity. Effects of these metal oxide NPs on rhizosphere functions are the focus of this review. These NPs at doses of 10 mg metal/kg and above change production of key metabolites involved in plant protection in a root-associated microbe, Pseudomonas chlororaphis O6...

Growing bodies of data show that psychological stress can be associated with hair loss and vitiligo. Researchers have revealed that stress could indeed inhibit hair growth in vivo, but the relationship between chronic stress and melanogenesis remains unknown. In this study, we established two types of stress models, chronic restraint stress (CRS) and chronic unpredicted mild stress (CUMS) mice models, and explored the possible role of stress in mice hair follicle melanogenesis. We found that stress changed hippocampal morphology, decreased 5-HT level in brain and skin and down-regulated 5-HT1A receptor expression in hippocampal CA1 region and skin...
