Suppressing the Inflammatory Prostaglandin Signaling after Thrombotic Stroke Ameliorates Ischemic Brain Injury and Facilitates Poststroke Recovery.

Acute cerebral ischemia is a leading cause of death and disability, particularly among old adults. The narrow therapeutic window and risk of hemorrhagic transformation largely limit patient eligibility for the current treatment. The neuroinflammatory signaling pathway involving the prostaglandin E2 (PGE) receptor subtype EP2 has now been clarified to contribute to the secondary neurotoxicity following ischemic stroke.

Aptamer Proteolysis-Targeting Chimeras (PROTACs): A Novel Strategy to Combat Drug Resistance in Estrogen Receptor α-Positive Breast Cancer.

Breast cancer with positive expression of estrogen receptor α (ERα+) accounts for 70% of breast cancer cases, whose predominant treatment is currently endocrine therapy. The main strategy of endocrine therapy for ERα+ breast cancer is to inhibit the ERα signaling pathway and downregulate ERα levels, which often results in mutations in the ligand-binding domain (LBD) of ERα, leading to significant resistance to subsequent treatment in patients. To combat drug resistance, we first proposed a novel aptamer PROTAC strategy through specifically targeted degradation of ERα via targeting the DNA-binding domain (DBD) of ERα.

Evolutionary conservation analysis of human sphingomyelin metabolism pathway genes.

Sphingomyelin is an important member of the sphingolipid family and was first reported more than a century ago. It has been demonstrated that sphingomyelin plays a crucial role in compositing cell membranes and signaling pathways. Despite extensive functional studies on the sphingolipid metabolism pathway genes, one intriguing question remains: how does the emergence of these genes during evolution correlate with the acquisition of new functions in different species? By employing an evolutionary conservation analysis, the sequence of occurrence of biological processes during evolutionary history can be elucidated.

Leveraging printability and biocompatibility in materials for printing implantable vessel scaffolds.

Vessel scaffolds are crucial for treating cardiovascular diseases (CVDs). It is currently feasible to fabricate vessel scaffolds from a variety of materials using traditional fabrication methods, but the risks of thrombus formation, chronic inflammation, and atherosclerosis associated with these scaffolds have led to significant limitations in the clinical usages. Bioprinting, as an emerging technology, has great potential in constructing implantable vessel scaffolds.

Dephosphorylation-related signature predicts the prognosis of papillary renal cell carcinoma.

Background: Phosphorylation-dephosphorylation is one of the most common and critical cellular activities. It is essential for cell cycle control and leads to large changes in protein conformation, which can alter protein function and coordinate multiple functions such as cell metabolism, gene transcription and translation, signaling, growth, differentiation, and apoptosis. Alterations in the phosphorylated proteome have been shown in many cancers.

Eyelid Reconstruction.

Reconstruction of the eyelid is a complex process that requires an understanding of eyelid anatomy and various reconstructive techniques to restore function and appearance. The eyelids, essential for globe protection, moisture retention, and expression, contain the lacrimal system and intricate musculature that make reconstruction challenging. Tumor excision commonly results in defects in the eyelid that require careful reconstructive planning, with consideration for defect dimensions, location, and involvement of surrounding tissue.

Targeting extracellular matrix stiffness for cancer therapy.

The physical characteristics of the tumor microenvironment (TME) include solid stress, interstitial fluid pressure, tissue stiffness and microarchitecture. Among them, abnormal changes in tissue stiffness hinder drug delivery, inhibit infiltration of immune killer cells to the tumor site, and contribute to tumor resistance to immunotherapy. Therefore, targeting tissue stiffness to increase the infiltration of drugs and immune cells can offer a powerful support and opportunities to improve the immunotherapy efficacy in solid tumors.
