https://www.selleckchem.com/products/gkt137831.html Bacteria and cancer cells share a common trait-both possess an electronegative surface that distinguishes them from healthy mammalian counterparts. This opens opportunities to repurpose antimicrobial peptides (AMPs), which are cationic amphiphiles that kill bacteria by disrupting their anionic cell envelope, into anticancer peptides (ACPs). To test this assertion, we investigate the mechanisms by which a pathogen-specific AMP, originally designed to kill bacterial Tuberculosis, potentiates the lytic destruction of drug-resistant cancers and synergistically enhances chemotherapeutic potency. peptide design, paired with cellular assays, elucidate structure-activity relationships (SAR) important to ACP potency and specificity. Using the sequence MAD1, microscopy, spectrophotometry and flow cytometry identify the peptide's anticancer mechanisms, while parallel combinatorial screens define chemotherapeutic synergy in drug-resistant cell lines and patient derived tumors. SAR investigations reveal spatial al of this strategy to open a wealth of synthetic biotherapies that offer new, combinatorial opportunities against drug resistant tumors. Tissue ischemia contributes to necrosis and infection. While angiogenic cell therapies have emerged as a promising strategy against ischemia, current approaches to cell therapies face multiple hurdles. Recent advances in nuclear reprogramming could potentially overcome some of these limitations. However, under severely ischemic conditions necrosis could outpace reprogramming-based repair. As such, adjunctive measures are required to maintain a minimum level of tissue viability/activity for optimal response to restorative interventions. Here we explored the combined use of polymerized hemoglobin (PolyHb)-based oxygen nanocarriers with Tissue Nano-Transfection (TNT)-driven restoration to develop tissue preservation/repair strategies that could potentially be used as a first line of care.
