pH-Dependent Non-Covalent Release of Chemotherapy from Carriers
Discov Med. 2024 Mar;36(182):448-456. doi: 10.24976/Discov.Med.202436182.42.ABSTRACTAlthough Warburg discovered pH discrepancies between tumor and normal tissues nearly 100 years ago, developing therapies to take advantage of this concept was relatively slow for the first 70 years. During the last 30 years, there has been an exponential increase in the use of pH-dependent strategies for both low molecular weight drugs and nanoparticles. Two frequently discussed approaches are the chemotherapy's release from pH-sensitive covalent linkages of macromolecules or from pH-dependent disruption of charged polymeric nanoparticles. ...

Recent Progress of Chitosan Nanoparticles for the Development of Superior Delivery of Vaccines
Discov Med. 2024 Mar;36(182):457-466. doi: 10.24976/Discov.Med.202436182.43.ABSTRACTChitosan seems to be an innovative biological material potentially utilized as a nanoparticle carrier for drug delivery, which could be low toxic, biocompatible, and easy to prepare. Chitosan nanoparticles have been employed in gene delivery. As a type of multifunctional adjuvant, chitosan nanoparticles could activate the phosphoinositide 3-kinase (PI3K)/AKT signaling pathway to induce cell protection and/or proliferation via the modulation of autophagy within dendritic cells. In general, adjuvants may improve the innate and/or adaptive imm...

Rare but Still There: A Scoping Review on Endometriosis-Associated Ovarian Cancer
Discov Med. 2024 Mar;36(182):467-481. doi: 10.24976/Discov.Med.202436182.44.ABSTRACTEndometriosis is a medical condition affecting at least up to 10% of women of reproductive age. This condition occurs when ectopic endometrial glands and stroma implant outside the uterus and there are several theories regarding the underlying origins of the disease. Endometriosis is one of the major causes of severe dysmenorrhoea, chronic pelvic pain and infertility. While endometriosis is generally a non-malignant condition, it rarely may transform into an invasive cancer, and increase the risk for epithelial ovarian cancer, notably endom...

Mechanical Stretch-Induced ATP Release from Osteocytes Promotes Osteogenesis of Bone Marrow Mesenchymal Stem Cells
CONCLUSIONS: The stretch stimulation of Piezo1 induces calcium influx, which in turn promotes calcium-related TAZ nuclear translocation, changes in mitochondrial dynamics, and the release of ATP in osteocytes. This signaling cascade leads to an up-regulation in the osteogenic capacity of BM-MSCs. Mitochondrial energy metabolism of mechanosensitive protein Piezo1-dependent and ATP release may provide a new effective intervention method for mechanically related bone remodeling.PMID:38531790 | DOI:10.24976/Discov.Med.202436182.46 (Source: Discovery Medicine)
