Integrated Multi-Omics Analysis Reveals Glycosylation Involving 2-O-β-D-Glucopyranosyl-L-Ascorbic Acid Biosynthesis in .

L-ascorbic acid (vitamin C, AA) is widely present in plants, but humans lack the ability to synthesize it independently. As a potent reducing agent, AA is susceptible to oxidation, making the enhancement of its stability crucial. 2-O-β-D-glucopyranosyl-L-ascorbic acid (AA-2βG) is a stable natural derivative of AA with glycosylation, initially discovered in the fruits of .

Mechanistic studies of Ca-induced classical pyroptosis pathway promoting renal adhesion on calcium oxalate kidney stone formation.

This study aims to investigate the role of hypercalciuria and pyroptosis in the formation of calcium oxalate kidney stones. Bioinformatics analysis was performed to compare the correlation of pyroptosis scores and cell adhesion scores between Randall's plaques and normal tissues from kidney stone patients. For the in vitro experiments, we investigated the effects of high concentrations of Ca on the pyroptosis and adhesion levels of renal tubular epithelial cells and examined the adhesion levels and crystal aggregation of the cells in high Ca concentrations environment by knockdown and overexpression of the key pyroptosis gene, GSDMD, and we verified the effects of Ca concentration on pyroptosis and adhesion levels, kidney injury, and crystal deposition by in vivo experiments.

The anti-cancer activity of Dioscin: an update and future perspective.

Natural drugs have the advantages of multi-pathway, multi-target, low toxicity, and high efficiency, which make them widely used and effective in anti-tumor therapy. Dioscin is a steroidal saponin compound that can be extracted from Dioscaceae plants. In recent years, it has been found that Dioscin has potent anti-tumor effects, can inhibit tumor cell proliferation, induce apoptosis and autophagy, inhibits tumor cell metastasis, reverses multidrug resistance, and increases sensitivity to anticancer drugs, and thus inhibit tumor progression.

Foxo1 directs the transdifferentiation of mouse Sertoli cells into granulosa-like cells.

Sertoli and granulosa cells, the initial differentiated somatic cells in bipotential gonads, play crucial roles in directing male and female gonad development, respectively. The transcription factor Foxo1 is involved in diverse cellular processes, and its expression in gonadal somatic cells is sex-dependent. While Foxo1 is abundantly expressed in ovarian granulosa cells, it is notably absent in testicular Sertoli cells.

Neural substrates for regulating self-grooming behavior in rodents.

Grooming, as an evolutionarily conserved repetitive behavior, is common in various animals, including humans, and serves essential functions including, but not limited to, hygiene maintenance, thermoregulation, de-arousal, stress reduction, and social behaviors. In rodents, grooming involves a patterned and sequenced structure, known as the syntactic chain with four phases that comprise repeated stereotyped movements happening in a cephalocaudal progression style, beginning from the nose to the face, to the head, and finally ending with body licking. The context-dependent occurrence of grooming behavior indicates its adaptive significance.

Methods: Clinical data of two children who were admitted to the Third Affiliated Hospital of Zhengzhou University respectively in April 2020 and April 2021 were retrospectively analyzed. Peripheral blood samples of the children and their parents were collected and subjected to whole exome sequencing.

Circular RNA-encoded oncogenic PIAS1 variant blocks immunogenic ferroptosis by modulating the balance between SUMOylation and phosphorylation of STAT1.

Background: The clinical response rate to immune checkpoint blockade (ICB) therapy in melanoma remains low, despite its widespread use. Circular non-coding RNAs (circRNAs) are known to play a crucial role in cancer progression and may be a key factor limiting the effectiveness of ICB treatment.

Methods: The circRNAs that were downregulated after coadministration compared with single administration of PD-1 inhibitor administration were identified through RNA-seq and Ribo-seq, and thus the circPIAS1 (mmu_circ_0015773 in mouse, has_circ_0008378 in human) with high protein coding potential was revealed.

Thioctic Acid-Based Solvent-Free and Recoverable Adhesive for Dry/Wet Environments.

Metal adhesive synthesis typically involves heating and solvents, and the resultant adhesives lack degradability and suffer from recycling and sustainable problems. Herein, we developed a solvent-free and chemically degradable biobased adhesive (p(Elp-TA)+PVP) from thioctic acid (TA), its derivative (Elp), and polyvinylpyrrolidone (PVP). Through a rapid acid-triggered cationic ring-opening polymerization of dithiolane at ambient conditions, p(Elp-TA)+PVP adhesive could build up a strong lap shear strength of 1123 kPa in air and an underwater lap shear strength of 534 kPa to the copper plate.

Magnamosis improves the healing of gastrojejunal anastomosis and down-regulates TGF-β1 and HIF-1α in rats.

This study elucidated the unique pathological features of tissue healing by magnamosis and revealed the changes in landmark molecule expression levels related to collagen synthesis and tissue hypoxia. Forty-eight male Sprague-Dawley rats were divided into the magnamosis and suture anastomosis groups, and gastrojejunal anastomosis surgery was performed. Rats were dissected at 6, 24, and 48 h and 5, 6, 8, 10, and 12 days postoperatively.

Blood-Brain Barrier Permeability is Affected by Changes in Tight Junction Protein Expression at High-Altitude Hypoxic Conditions-this may have Implications for Brain Drug Transport.

Changes to blood-brain barrier structure and function may affect the delivery of drugs into the brain. It is worthwhile to exploring more study on how the blood-brain barrier changes in structure and function and how that affects drug transport in high-altitude hypoxic environment. The DIA high-throughput sequencing technique indicate that the rats blood-brain barrier has been identified to have 7252 proteins overall and 8 tight junction proteins, among which Claudin-7 was a plateau-specific tight junction protein under high-altitude hypoxia, and based on the interaction network study, 2421 proteins are found to interact with one another, with ZO-1 being the primary target.

Mitophagy Promotes Hair Regeneration by Activating Glutathione Metabolism.

The mechano-chemical circuit in fibroblasts and dendritic cells drives basal cell proliferation in psoriasis.

Psoriasis is an intractable immune-mediated disorder that disrupts the skin barrier. While studies have dissected the mechanism by which immune cells directly regulate epidermal cell proliferation, the involvement of dermal fibroblasts in the progression of psoriasis remains unclear. Here, we identified that signals from dendritic cells (DCs) that migrate to the dermal-epidermal junction region enhance dermal stiffness by increasing extracellular matrix (ECM) expression, which further promotes basal epidermal cell hyperproliferation.
