Diabetic nephropathy (DKD) is a diabetesrelated kidney injury with an increasing incidence every year. Metformin hydrochloride (MET), a cornerstone treatment for glucose lowering, has been widely reported for the treatment of DKD, but the specific molecular mechanisms and potential therapeutic targets still need to be further explored. We used kidney tissues from db/db mice as samples and used proteomics and bioinformatics to analyse the function, distribution and related pathways of differential proteins in DKD, focusing on the assessment of the binding energies of key proteins in the butyrate pathway and drugs at the molecular level, which showed that the expression profiles of differential proteins in kidney tissues were altered after MET treatment, involving energy metabolism.

Plants have mechanisms to transport secondary metabolites from where they are biosynthesized to the sites where they function, or to sites such as the vacuole for detoxification. However, current research has mainly focused on metabolite biosynthesis and regulation, and little is known about their transport. Tanshinone, a class diterpenoid with medicinal properties, is biosynthesized in the periderm of Salvia miltiorrhiza roots.

  • A study explored the causal relationship between heme oxygenase-1 (HO-1) and asthma using a two-sample Mendelian randomization approach, analyzing data from genome-wide association studies.
  • The findings suggested that higher levels of genetically predicted HO-1 are associated with a lower risk of developing asthma, confirming its protective role.
  • In contrast, asthma did not appear to influence HO-1 levels, and these results were consistent across additional datasets and in childhood asthma cases.

  • Androgen-ablative therapies effectively target AR+ prostate cancer cells but lead to an increase in AR- prostate cancer cell subtypes.
  • The study identified CXCL8 as a key factor promoting the survival of AR- prostate cancer cells, which become more prevalent after therapy.
  • The findings show that androgen-ablative treatments suppress AR signaling, causing an increase in CXCL8 that activates the mTORC1 pathway, ultimately enhancing tumor growth in AR- cells.

Flavonoids, the largest class of polyphenols, exhibit substantial structural and functional diversity, yet their evolutionary diversification and specialized functions remain largely unexplored. The genus Scutellaria is notable for its rich flavonoid diversity, particularly of 6/8-hydroxylated variants biosynthesized by the cytochrome P450 subfamily CYP82D. Our study analyzes metabolic differences between Scutellaria baicalensis and Scutellaria barbata, and the results suggest that CYP82Ds have acquired a broad range of catalytic functions over their evolution.
