Alkyl chain length-regulated intelligent nano-assemblies with AIE-active photosensitizers for photodynamic cancer therapy.

Photodynamic therapy (PDT) brings new hope for the treatment of breast cancer due to few side effects and highly effective cell killing; however, the low bioavailability of traditional photosensitizers (PSs) and their dependence on oxygen severely limits their application. Aggregation-induced emission (AIE) PSs can dramatically facilitate the photosensitization effect, which can have positive impacts on tumor PDT. To-date, most AIE PSs lack tumor targeting capability and possess poor cell delivery, resulting in their use in large quantities that are harmful to healthy tissues.

Identification of the critical residues of TMPRSS2 for entry and host range of human coronavirus HKU1.

Human coronavirus (CoV) HKU1 infection typically causes common cold but can lead to pneumonia in children, older people, and immunosuppressed individuals. Recently, human transmembrane serine protease 2 (hTMPRSS2) was identified as the functional receptor for HKU1, but its region and residues critical for HKU1 S binding remain elusive. In this study, we find that HKU1 could utilize human and hamster, but not rat, mouse, or bat TMPRSS2 for virus entry, displaying a narrow host range.

This optimized MS approach identifies 6,201 and 7,466 human proteins with 1- and 2-min gradients, respectively.

Therapeutic modulation of ROCK overcomes metabolic adaptation of cancer cells to OXPHOS inhibition and drives synergistic anti-tumor activity.

Genomic studies have identified frequent mutations in subunits of the SWI/SNF chromatin remodeling complex including and in non-small cell lung cancer. Previously, we and others have identified that -mutant lung cancers are highly dependent on oxidative phosphorylation (OXPHOS). Despite initial excitements, therapeutics targeting metabolic pathways such as OXPHOS have largely been disappointing due to rapid adaptation of cancer cells to inhibition of single metabolic enzymes or pathways, suggesting novel combination strategies to overcome adaptive responses are urgently needed.

Inhibition of hepatic oxalate overproduction ameliorates metabolic dysfunction-associated steatohepatitis.

The incidence of metabolic dysfunction-associated steatohepatitis (MASH) is on the rise, and with limited pharmacological therapy available, identification of new metabolic targets is urgently needed. Oxalate is a terminal metabolite produced from glyoxylate by hepatic lactate dehydrogenase (LDHA). The liver-specific alanine-glyoxylate aminotransferase (AGXT) detoxifies glyoxylate, preventing oxalate accumulation.
