GABA receptors regulate the neural stem cell potential of Pkd2l1 cerebrospinal fluid-contacting neurons via the PI3K/Akt signaling pathway.

Cerebrospinal fluid-contacting neurons (CSF-cNs) exhibit neural stem cell (NSC) properties both in vitro and in vivo, and they may play a critical role in recovery after spinal cord injury (SCI). GABA receptors (GABABRs) are expressed in Pkd2l1 CSF-cNs. However, their role in Pkd2l1 CSF-cNs still needs to be discovered.

IGF2BP3 Triggers STAT3 Pathway by Stabilizing SRC RNA in an m6A-Dependent Manner to Promote Lymphatic Metastasis in LUAD.

Lymph node metastasis significantly affects the NSCLC patients' staging, treatment strategy, and prognosis. Studies have shown that IGF2BP3, an oncofetal protein and an m6A reader, overexpresses and correlates to lymph node metastasis and worse overall survival in histopathological studies including NSCLC, but its mechanism needs further study. This study explored IGF2BP3's function and mechanism in LUAD lymphatic metastasis using public databases, a human LUAD tissue microarray, human LUAD cells, and a lymphatic metastasis model in male BALB/c nude mice.

Regulation of PPARγ in the development of early sheep embryos in vitro.

Lipid metabolism plays an important role in the regulation of early embryonic development in mammals. However, the effect of lipid metabolism mediated by peroxisome proliferator-activated receptor γ (PPARγ) on the early embryonic development of sheep remains unclear. In this study, rosiglitazone (RSG), a PPARγ activator, was added to the in vitro embryo culture (IVC) medium to regulate the continuous expression of PPARγ.

Restoring sweat gland function in mice using regenerative sweat gland cells derived from chemically reprogrammed human epidermal keratinocytes.

The regeneration of sweat glands (SwGs) plays a pivotal role in the functional recovery of extensive skin wounds. Recent research has illuminated the possibility of reprogramming human epidermal keratinocytes (HEKs) into induced SwG cells through the ectopic expression of ectodysplasin A. However, the clinical application of this genetic manipulation approach is inherently limited.

Chiral helix amplification and enhanced bioadhesion of two-component low molecular weight hydrogels regulated by OH to eradicate MRSA biofilms.

The supramolecular chemistry of small chiral molecules has attracted widespread attention owing to their similarity to natural assembly codes. Two-component low-molecular-weight (LMW) hydrogels are crucial as they form helical structures chirality transfer, enabling diverse functions. Herein, we report a pair of two-component chiral LMW hydrogels based on the small molecular drugs baicalin (BA), scutellarin (SCU) and berberine (BBR).

Programmable Artificial Skins Accomplish Antiscar Healing with Multiple Appendage Regeneration.

Functional appendage regeneration is essential for skin rehabilitation, but it has always failed by current existing healing approaches, owing to their inefficacy in preventing disfiguring scars. In this study, a novel regeneration-directing artificial skin (RDAS) system is presented, which is based on the rational design of multi-layered hydrogels that closely mimic natural skin matrices. By leveraging the programmability and architectural rigidity of DNA components, without the need for exogenous cell transplantation, such RDAS effectively minimizes tissue fibrosis by accurately guiding the regenerative process in wound fibroblasts, enabling rapid scarless wound repair, restoration of dermal function, and successful in situ regeneration of multiple appendages, such as hair follicles (HFs), sebaceous glands (SGs), and sweat glands (SwGs).

Radiation drives tertiary lymphoid structures to reshape TME for synergized antitumour immunity.

Radiotherapy (RT) plays a key role in the tumour microenvironment (TME), impacting the immune response via cellular and humoral immunity. RT can induce local immunity to modify the TME. It can stimulate dendritic cell maturation and T-cell infiltration.

Effects of Exogenous Regulation of PPARγ on Ovine Oocyte Maturation and Embryonic Development In Vitro.

Lactating oocytes consume a lot of energy during maturation, a large part of which comes from lipid metabolism. PPARγ is a key regulator of lipid metabolism. In this study, rosiglitazone (RSG), an activator of PPARγ, was added to a mature medium to investigate its effects on the levels of spindle and the chromosome arrangement, lipid deposition, reactive oxygen species (ROS), and glutathione (GSH) levels, oocyte secretion factors, apoptosis and lipid metabolism-related gene expression, and subsequent embryonic development during the maturation of sheep oocytes.

Boosting Oxygen Evolution Reaction Performance on NiFe-Based Catalysts Through d-Orbital Hybridization.

Anion-exchange membrane water electrolyzers (AEMWEs) for green hydrogen production have received intensive attention due to their feasibility of using earth-abundant NiFe-based catalysts. By introducing a third metal into NiFe-based catalysts to construct asymmetrical M-NiFe units, the d-orbital and electronic structures can be adjusted, which is an important strategy to achieve sufficient oxygen evolution reaction (OER) performance in AEMWEs. Herein, the ternary NiFeM (M: La, Mo) catalysts featured with distinct M-NiFe units and varying d-orbitals are reported in this work.

Preclinical Evaluation of STI-8811, a Novel Antibody-Drug Conjugate Targeting BCMA for the Treatment of Multiple Myeloma.

Treatment for patients with multiple myeloma has experienced rapid development and improvement in recent years; however, patients continue to experience relapse, and multiple myeloma remains largely incurable. B-cell maturation antigen (BCMA) has been widely recognized as a promising target for treatment of multiple myeloma due to its exclusive expression in B-cell linage cells and its critical role in the growth and survival of malignant plasma cells. Here, we introduce STI-8811, a BCMA-targeting antibody-drug conjugate (ADC) linked to an auristatin-derived duostatin payload via an enzymatically cleavable peptide linker, using our proprietary C-lock technology.

Isolated Cryptococcal Infection of the Thoracic Spine in an Immunocompetent Patient.

Cryptococcus neoformans is a type of fungal infection, which primarily affects the central nervous system and lungs of immunocompromised individuals. Spinal infections are known to be a rare manifestation of cryptococcosis. Herein, we report a case of a patient with isolated nonspecific spinal lesions at the T10 vertebra.

Flexible Sono-Piezo Patch for Functional Sweat Gland Repair through Endogenous Microenvironmental Remodeling.

Remodeling the endogenous regenerative microenvironment in wounds is crucial for achieving scarless, functional tissue regeneration, especially the functional recovery of skin appendages such as sweat glands in burn patients. However, current approaches mostly rely on the use of exogenous materials or chemicals to stimulate cell proliferation and migration, while the remodeling of a pro-regenerative microenvironment remains challenging. Herein, we developed a flexible sono-piezo patch (fSPP) that aims to create an endogenous regenerative microenvironment to promote the repair of sweat glands in burn wounds.

Roles of cerebrospinal fluid-contacting neurons as potential neural stem cells in the repair and regeneration of spinal cord injuries.

Cerebrospinal fluid-contacting neurons (CSF-cNs) represent a distinct group of interneurons characterized by their prominent apical globular protrusions penetrating the spinal cord's central canal and their basal axons extending towards adjacent cells. Identified nearly a century back, the specific roles and attributes of CSF-cNs have just started to emerge due to the historical lack of definitive markers. Recent findings have confirmed that CSF-cNs expressing PKD2L1 possess attributes of neural stem cells, suggesting a critical function in the regeneration processes following spinal cord injuries.

Cross-media transfer of polycyclic aromatic hydrocarbons in the Naples metropolitan area, southern Italy.

At present, an in-depth knowledge of polycyclic aromatic hydrocarbons (PAHs) in the multimedia system of the urban environment remains limited. Taking the Naples metropolitan area (NMA) for instance, we simulated the cross-media transfer of PAHs using a multimedia urban model, involving air, water, soil, sediment, vegetation, and impervious film. The results indicated that the predicted PAH values in 2015 match well with their corresponding in-situ monitoring data.

TAF2, within the TFIID complex, regulates the expression of a subset of protein-coding genes.

TFIID, one of the general transcription factor (GTF), regulates transcriptional initiation of protein-coding genes through direct binding to promoter elements and subsequent recruitment of other GTFs and RNA polymerase II. Although generally required for most protein-coding genes, accumulated studies have also demonstrated promoter-specific functions for several TFIID subunits in gene activation. Here, we report that TBP-associated factor 2 (TAF2) specifically regulates TFIID binding to a small subset of protein-coding genes and is essential for cell growth of multiple cancer lines.
