Targeted protein degradation (TPD) represents a promising therapeutic approach, encompassing several innovative strategies, including but not limited to proteolysis targeting chimeras (PROTACs), molecular glues, hydrophobic tag tethering degraders (HyTTD), and lysosome-targeted chimeras (LYTACs). Central to TPD are small molecule ligands, which play a critical role in mediating the degradation of target proteins. This review summarizes the current landscape of small molecule ligands for TPD molecules.

Background: Immune checkpoint inhibitors play an important role in the treatment of solid tumors, but the currently used immune checkpoint inhibitors targeting programmed cell death-1 (PD-1), programmed cell death ligand-1 (PD-L1), and cytotoxic T-lymphocyte antigen-4 (CTLA-4) show limited clinical efficacy in many breast cancers. B7H3 has been widely reported as an immunosuppressive molecule, but its immunological function in breast cancer patients remains unclear.

Methods: We analyzed the expression of B7H3 in breast cancer samples using data from the Cancer Genome Atlas Program (TCGA) and the Gene Expression Omnibus (GEO) databases.

The transcriptional regulatory factors binding to the polymorphic site C-1888T in the promoter region of the palate, lung, and nasal epithelium clone (PLUNC) gene were identified to investigate whether the C-1888T polymorphic site affects the transcriptional regulation and function of PLUNC gene. Three genotypes of C-1888T polymorphic locus were screened from established nasopharyngeal carcinoma (NPC) cells, and the mRNA expression levels of PLUNC gene in different genotypes were detected. The respective transcription factors that were more likely to bind with A or G in SNP were predicted by biological information and preliminarily verified in vitro by gel electrophoresis migration rate analysis.

Background: Tumor-derived exosomes are involved in tumor progression and immune invasion and might function as promising noninvasive approaches for clinical management. However, there are few reports on exosom-based markers for predicting the progression and adjuvant therapy response rate among patients with clear cell renal cell carcinoma (ccRCC).

Methods: The signatures differentially expressed in exosomes from tumor and normal tissues from ccRCC patients were correspondingly deregulated in ccRCC tissues.

Resveratrol-Loaded Versatile Nanovesicle for Alopecia Therapy via Comprehensive Strategies.

Int J Nanomedicine

December 2024

School of Pharmaceutical Sciences, Sun Yat-Sen University, Guangzhou, Guangdong Province, People's Republic of China.

Introduction: Alopecia is a systemic disease with multiple contributing factors. Effective treatment is challenging when only hair growth mechanisms are targeted while ignoring the role of maintaining hair follicle microenvironment homeostasis, which is crucial for cell growth and angiogenesis. Oxidative stress and inflammation are major disruptors of this microenvironment, leading to inhibited cell proliferation and compromised hair follicle circulation.
