Evaluation of Protocols for DNA Extraction from Individual to Assess Pyrethroid Resistance Using Genotyping Real-Time Polymerase Chain Reaction.

is a major vector of pathogens, including West Nile and Usutu viruses, that poses a significant public health risk. Monitoring pyrethroid resistance in mosquito populations is essential for effective vector control. This study aims to evaluate four DNA extraction protocols-QIAsymphony, DNAzol Direct reagent, PrepMan Ultra Sample Preparation Reagent (USPR), and Chelex 100-to identify an optimal method to extract DNA from individual , as part of a high-throughput surveillance of pyrethroid resistance using Real-Time Genotyping PCR.

A fully human IgG1 antibody targeting connexin 32 extracellular domain blocks CMTX1 hemichannel dysfunction in an in vitro model.

Connexins (Cxs) are fundamental in cell-cell communication, functioning as gap junction channels (GJCs) that facilitate solute exchange between adjacent cells and as hemichannels (HCs) that mediate solute exchange between the cytoplasm and the extracellular environment. Mutations in the GJB1 gene, which encodes Cx32, lead to X-linked Charcot-Marie-Tooth type 1 (CMTX1), a rare hereditary demyelinating disorder of the peripheral nervous system (PNS) without an effective cure or treatment. In Schwann cells, Cx32 HCs are thought to play a role in myelination by enhancing intracellular and intercellular Ca signaling, which is crucial for proper PNS myelination.

Metabolites derived from gut microbiota mitigate chemoresistance in pancreatic cancer.

Introduction: Pancreatic ductal adenocarcinoma (PDAC) is the third-leading cause of tumor-related deaths. The gut microbiota has gained attention in cancer treatment, due to its influence on the immune system and drug activity.

Areas Covered: Tintelnot and collaborators highlight distinct gut microbiota composition in metastatic PDAC (mPDAC) patients responding versus non-responding to chemotherapy.
