Hematopoietic progenitor kinase 1 (HPK1) has emerged as a promising target for cancer immunotherapy due to its critical role as a negative regulator of T cell receptor (TCR) signaling. Despite this potential, no HPK1 inhibitors have been approved for cancer treatment, underscoring the need for structurally novel inhibitors. Herein, we describe the design, synthesis and biological evaluation of a series of potent HPK1 inhibitors based on our previously identified hit 9.

State Key Laboratory of Pollution Control and Resource Reuse, School of the Environment, Nanjing University, Nanjing 210023, China.

The abrasion of melamine cleaning sponges release microplastic fibers (MPFs) into the environment, yet the potential risks remain unknown. Here, we evaluated the ingestion, elimination, and toxic effects of melamine MPFs on Daphnia magna through acute and chronic exposures. This new type of MPFs displayed different morphology (a combination of linear and branched fibers with a length ranging from 10 to 157 μm) from the widely-studied MPFs released from textiles (longer and thicker linear fibers but no branched fibers).

Background: Health authorities worldwide have invested in digital technologies to establish robust information exchange systems for improving the safety and efficiency of medication management. Nevertheless, inaccurate medication lists and information gaps are common, particularly during care transitions, leading to avoidable harm, inefficiencies, and increased costs. Besides fragmented health care processes, the inconsistent incorporation of patient-driven changes contributes to these problems.

Detection and Treatment with Peptide Power: A New Weapon Against Bacterial Biofilms.

ACS Biomater Sci Eng

January 2025

Xiangya School of Pharmaceutical Sciences, Central South University, Changsha 410013, P. R. China.

Bacterial biofilms, complex microbial communities encased in a protective extracellular matrix, pose a significant threat to public health due to their inherent antibiotic resistance. This review explores the potential of peptides, particularly antimicrobial peptides (AMPs), as innovative tools to combat biofilm-related infections. AMPs, characterized by their potent antimicrobial activity and tissue permeability, offer a promising approach to overcome the challenges posed by biofilms.

Non-cryo and hypothermic preservations are two available options for short-term storage of living cells. For long-term cell storage, cryopreservation is an essential procedure as it prolongs the storage time, allowing for the transport and testing of cells, as well as the establishment of cell banks. But it is unclear whether cryopreservation reduces the therapeutic effects of human umbilical cord mesenchymal stem cells (hucMSCs) on osteoarthritis (OA).

Cells Good (Xiamen) Inc. Huli, Xiamen Torch Development Zone, Fujian, China.

Mesenchymal stem cells (MSCs) are pluripotent stem cells with self-renewal. They play a critical role in cell therapy due to their powerful immunomodulatory and regenerative effects. Recent studies suggest that one of the key therapeutic mechanisms of MSCs seems to derive from their paracrine product, called extracellular vesicles (EVs).

Evidence suggests that sodium nitrite may be effective in the treatment of hypertension and pulmonary hypertension. However, its use remains debated due to safety concerns. In response, a scoping review was conducted to map current knowledge on the efficacy and safety of sodium nitrite in patients with hypertension or pulmonary hypertension, addressing the question: What evidence supports the effectiveness and safety of using sodium nitrite in these patients? The databases MEDLINE (PubMed), EMBASE, Scopus, Web of Science, and LILACS were searched for clinical studies on hypertensive patients at any disease stage without restrictions on age, sex, ethnicity, publication date, or status.

Carboxy-Amidated AamAP1-Lys has Superior Conformational Flexibility and Accelerated Killing of Gram-Negative Bacteria.

Biochemistry

January 2025

Department of Biochemistry, Genetics and Microbiology, Faculty of Natural and Agricultural Sciences, University of Pretoria, Pretoria 0002, South Africa.

C-terminal amidation of antimicrobial peptides (AMPs) is a frequent minor modification used to improve antibacterial potency, commonly ascribed to increased positive charge, protection from proteases, and a stabilized secondary structure. Although the activity of AMPs is primarily associated with the ability to penetrate bacterial membranes, hitherto the effect of amidation on this interaction has not been understood in detail. Here, we show that amidation of the scorpion-derived membranolytic peptide AamAP1-Lys produces a potent analog with faster bactericidal activity, increased membrane permeabilization, and greater Gram-negative membrane penetration associated with greater conformational flexibility.

The role of the electron transport chain (ETC) in cell proliferation control beyond its crucial function in supporting ATP generation has recently emerged. In this study, we found that, among the four ETC complexes, the complex I (CI)-mediated NAD regeneration is important for cancer cell proliferation. In cancer cells, a decrease in CI activity by RNA interference (RNAi) against NADH:ubiquinone oxidoreductase core subunit V1 (NDUFV1) arrested the cell cycle at the G/S phase, accompanying upregulation of p21 cyclin-dependent kinase inhibitor expression.

School of Chemistry, University of Southampton, Highfield, Southampton SO17 1BJ, United Kingdom.

Membrane properties are determined in part by lipid composition, and cholesterol plays a large role in determining these properties. Cellular membranes show a diverse range of cholesterol compositions, the effects of which include alterations to cellular biomechanics, lipid raft formation, membrane fusion, signaling pathways, metabolism, pharmaceutical therapeutic efficacy, and disease onset. In addition, cholesterol plays an important role in non-cellular membranes, with its concentration in the skin lipid matrix being implicated in several skin diseases.
