[Mycology, chemical components, bioactivities, and fermentation process regulation of Sanghuang: a review].

Sanghuang, a famous ethnomedicine widely used in China, Japan, Korea and other countries for a long history, is produced from the dried fruiting bodies of the medical fungi belonging to Sanghuangporus. With abundant bioactive natural chemicals including polysaccharides, flavonoids, triterpenoids, and polyphenols, Sanghuang exhibits anticancer, antioxidant, blood glucose-and lipid-lowering, liver protecting, anti-inflammatory, antimicrobial, and gout symptom-relieving effects, thus demonstrating broad application and development prospects in the pharmaceutical and food fields. However, the sustainable development of Sanghuang resources is limited by the scarce stock of wild resources, the diverse original fungi of cultivated Sanghuang, the inconsistency of local standards of Sanghuang materials or products, and the lagging application of Sanghuangporus mycelia.

Roles of acyl carrier proteins in ladderane fatty acid producing-organisms.

Ladderanes are highly strained hydrocarbons consisting of two or more linearly concatenated cyclobutane rings. Strikingly, ladderane moieties are part of unique fatty acids and fatty alcohols that are exclusively found in the membrane lipids of anaerobic ammonium-oxidizing (anammox) bacteria. These bacteria express a distinctive gene cluster (cluster I) that has been suggested to be responsible for ladderane fatty acid (FA) biosynthesis in addition to a cluster likely involved in canonical FA biosynthesis (cluster III).

Engineered hypoxia-responsive albumin nanoparticles mediating mitophagy regulation for cancer therapy.

Hypoxic tumors present a significant challenge in cancer therapy due to their ability to adaptation in low-oxygen environments, which supports tumor survival and resistance to treatment. Enhanced mitophagy, the selective degradation of mitochondria by autophagy, is a crucial mechanism that helps sustain cellular homeostasis in hypoxic tumors. In this study, we develop an azocalix[4]arene-modified supramolecular albumin nanoparticle, that co-delivers hydroxychloroquine and a mitochondria-targeting photosensitizer, designed to induce cascaded oxidative stress by regulating mitophagy for the treatment of hypoxic tumors.

Refining risk stratification for B-cell precursor Adult Acute Lymphoblastic Leukemia treated with a Pediatric-inspired Regimen by Combining IKZF1 deletion and Minimal Residual Disease.

Unlabelled: Minimal residual disease (MRD) is the most important prognostic factor for B-cell acute lymphoblastic leukemia (B-ALL) however nearly 20-30% of patients relapsed even when they achieved negative MRD, how to identify these patients is less addressed. In this study, we aimed to reassess the prognostic significance of MRD and IKZF1 in adult B-ALL patients receiving pediatric chemotherapy regimens. In the PDT-ALL-2016 cohort (NCT03564470), adult B-ALL patients were treated with a pediatric-inspired regimen; patients were redefined as standard (MRD-negative and IKZF1wild-type), intermediate (MRD-positive or IKZF1 deletion), and high-risk (MRD-positive and IKZF1 deletion) groups by combining IKZF1 deletion status and MRD.
