Unlocking the Hidden Potential of Cancer Therapy Targeting Lysine Succinylation.

Lysine succinylation is an emerging post-translational modification of proteins. It involves the addition of the succinyl group to lysine residues of target proteins through both enzymatic and non-enzymatic pathways. This modification can alter the structure of the target protein, which, in turn, impacts protein activity and function and is involved in a wide range of diseases.

IGF2BPs-regulated TIN2 confers the malignant biological behaviors of gastric cancer cells.

Background: Telomere maintenance is an important feature of tumor cells. Telomeric-repeat binding factor 1 interaction nuclear protein 2 (TIN2), a key member of the shelterin proteins, functions in regulating telomere structure, length and function. Our work sought to investigate the role of TIN2 in controlling gastric cancer (GC) malignant biological behaviors.

Selperctinib as neoadjuvant therapy for RET-altered papillary thyroid carcinoma: Two case reports.

Background: Locally advanced papillary thyroid carcinoma (PTC) with RET fusion-positive poses significant challenges for surgical resection due to tumor invasion into critical structures. Neoadjuvant targeted therapies are a promising approach to reduce the tumor burden and improve the resectability. Selperctinib, a RET kinase inhibitor, has been approved for the treatment of advanced or metastatic RET-altered thyroid cancer.

Widespread distribution of chlorophyll f-producing Leptodesmis cyanobacteria.

Chlorophyll (Chl) f was reported as the fifth Chl in oxygenic photoautotrophs. Chlorophyll f production expanded the utilization of photosynthetically active radiation into the far-red light (FR) region in some cyanobacterial genera. In this study, 11 filamentous cyanobacterial strains were isolated from FR-enriched habitats, including hydrophyte, moss, shady stone, shallow ditch, and microbial mat across Central and Southern China.

A Molecular Signature of the Ubiquitin-Proteasome System for Forecasting Prognosis in Thyroid Carcinoma Patients.

Background: The ubiquitin-proteasome system (UPS) is vital for protein quality control and its dysregulation is linked to diseases, including cancer. Targeting the UPS is becoming a promising approach in cancer therapy. However, the role of UPS modulation in thyroid carcinoma (THCA) remains to be fully elucidated.

Tailored Metal-Organic Framework-Based Nanozymes for Enhanced Enzyme-Like Catalysis.

The global crisis of bacterial infections is exacerbated by the escalating threat of microbial antibiotic resistance. Nanozymes promise to provide ingenious solutions. Here, we reported a homogeneous catalytic structure of Pt nanoclusters with finely tuned metal-organic framework (ZIF-8) channel structures for the treatment of infected wounds.

Clinicopathologic feature and treatment progress of high-grade ovarian neuroendocrine tumors.

High-grade Ovarian neuroendocrine tumors represent a rare subset of ovarian neoplasms characterized by aggressive behavior, poor prognosis, and early metastasis. Despite their clinical significance, the management of these tumors lacks consensus due to their low incidence. This comprehensive review encompasses literature spanning from 1991 to 2024, focusing on the clinical presentation, diagnostic criteria, differential diagnosis, prognostic indicators, treatment modalities, and recent advancements in the understanding of this condition.

Regulating Molecular Interactions in Polybenzimidazole Membrane for Efficient Vanadium Redox Flow Battery.

The tightly bonded structure of polybenzimidazole (PBI) membrane is the origin of its poor proton conductivity, which severely hinders achieving a cost-effective membrane for vanadium redox flow battery (VRFB). It desires a strategy to relax the membrane structure to significantly improve the proton conductivity and maintain its structure stability. Therefore, this work proposes a novel strategy through regulating molecular interactions within PBI membrane to loosen up the structure of PBI membrane and dramatically enhance the proton conductivity.

Leader RNA facilitates snakehead vesiculovirus (SHVV) replication by interacting with CSDE1 and hnRNP A3.

Leader RNAs are viral small non-coding RNAs that has been proved to play important roles in viral replication. Snakehead vesiculovirus (SHVV) is an aquatic virus that has caused huge economic loss in Chinese snakehead fish aquaculture industry. It has been proved that SHVV would generate leader RNA during the process of infection, and leader RNA could interact with viral nucleoprotein to promote viral replication.

Antibiotic-Loaded Dendrimer Hydrogels in Periodontal Bone Regeneration: An In Vitro Release Feasibility Study.

The prescription of a course of oral antibiotics following bone grafting procedures is a common practice in clinical periodontics to reduce surgical site infections. The goal of this study is to characterize the release profile of antibiotics via local delivery using dendrimer hydrogels (DH) and to analyze the effect of two different particulate bone allografts on the release of the antibiotics in vitro. DH were synthesized from polyamidoamine (PAMAM) dendrimer G5 and polyethylene glycol diacrylate, and cefazolin was chosen as the antibiotic.

LncRNA HIF1A-AS2 promotes triple-negative breast cancer progression and paclitaxel resistance via MRPS23 protein.

Dysregulation of lncRNAs is a critical factor in the migration and invasion of tumors. Here our study reveals that lncRNA HIF1A-AS2 is highly expressed in breast cancer tissues and various TNBC cell lines. Moreover, we present compelling evidence supporting the role of HIF1A-AS2 in promoting TNBC cell proliferation, metastasis, invasion, and resistance to paclitaxel treatment.

Single-Cell WGCNA Combined with Transcriptome Sequencing to Study the Molecular Mechanisms of Inflammation-Related Ferroptosis in Myocardial Ischemia-Reperfusion Injury.

Cutting-Edge Biomaterials in Intervertebral Disc Degeneration Tissue Engineering.

Intervertebral disc degeneration (IVDD) stands as the foremost contributor to low back pain (LBP), imposing a substantial weight on the world economy. Traditional treatment modalities encompass both conservative approaches and surgical interventions; however, the former falls short in halting IVDD progression, while the latter carries inherent risks. Hence, the quest for an efficacious method to reverse IVDD onset is paramount.
