Thiazolidinedione-based structure modification of ergosterol peroxide provides thiazolidinedione-conjugated derivatives as potent agents against breast cancer cells through a PI3K/AKT/mTOR pathway.

Ergosterol peroxide (EP) is a steroidal compound isolated from the traditional Chinese medicine Ganoderma lucidum. However, EP is limited by its solubility and moderate potency in antitumor studies. In the present study, a series of novel ergosterol peroxide-3-thiazolidinedione derivatives were designed and synthesized, by changing the linker between ergosterol peroxide and thiazolidinedione, it is expected to obtain compounds with better antitumor activity.

Strontium ranelate-loaded human hair keratin-hyaluronic acid hydrogel accelerates wound repair with anti-inflammatory and antioxidant properties.

Acetylation of PGK1 at lysine 323 promotes glycolysis, cell proliferation, and metastasis in luminal A breast cancer cells.

Background: In prior research employing iTRAQ (Isobaric Tags for Relative and Absolute Quantitation) technology, we identified a range of proteins in breast cancer tissues exhibiting high levels of acetylation. Despite this advancement, the specific functions and implications of these acetylated proteins in the context of cancer biology have yet to be elucidated. This study aims to systematically investigate the functional roles of these acetylated proteins with the objective of identifying potential therapeutic targets within breast cancer pathophysiology.

Effects of ultra-strong static magnetic field on the gut microbiota of humans and mice.

To explore the effect of ultra-strong static magnetic field on gut microbiota, 16 T static magnetic field was used to study the changes in the structure and composition of human and mouse gut microbiota in this environment. In the mouse gut microbiota, at the genus level, the magnetic field significantly decreased the relative abundances of Escherichia-Shigella, Lactobacillus, Enterococcus, Burkholderia-Caballeronia-Paraburkholderia, Parasutterella, and Ralstonia and significantly increased those of Parabacteroides, Alloprevotella, Alistipes, Odoribacter, Bacteroides, Mucispirillum, Sutterella, and Prevotellaceae_UCG-001. Similarly, at the genus level, the relative abundances of Bacteroides, Parabacteroides, Romboutsia, and Streptococcus significantly decreased in the human gut microbiota.

TOX3 protein expression is correlated with pathological characteristics in breast cancer.

TOX3 is a newly identified gene that has been observed to correlate with breast cancer by genome-wide association studies (GWAS) in recent years. In addition, it has been noted that single-nucleotide polymorphisms (SNPs) in the TOX3 gene have a strong correlation with estrogen receptor (ER)-positive tumors. However, the role of TOX3 in breast carcinoma development is still unclear.
