Oligoasthenospermia (OAS) is a global human developmental disease and the most common type of male infertility. There are currently no sufficiently effective therapeutic strategies for OAS. Pill (WZYZP) is a traditional Chinese prescription for the clinical treatment of male infertility, and its efficacy is well known in China. Therefore, due to the complexity of traditional Chinese medicine, the specific mechanism of action of WZYZP on OAS has not been elucidated. Astragalin (AG), one of the main active substances in WZYZP, has good antioxidant effect. The aim of this research is to investigate whether AG, the active substance in WZYZP, can treat OAS by promoting Nrf2 nuclear translocation and inhibiting ferroptosis. The OAS model was established by intraperitoneal injection of cyclophosphamide, and the therapeutic effects of AG and WZYZP on OAS were evaluated by detecting sperm quality, sex hormone levels and testicular pathological changes after intragastric administration of AG and WZYZP. Western blot was used to measure the expression levels of TFR1, SLC7A11, GPX4 and FTH1. The nuclear translocation of Nrf2 was detected by immunofluorescence staining and nuclear/intracellular expression of Nrf2. The results showed that AG could improve sperm quality and serum sex hormone levels in OAS rats, reduce the expression of testicular Fe and TFR1, up-regulate testicular SLC7A11, GPX4 and FTH1, and inhibit testicular ferroptosis. At the same time, AG can promote the expression and nuclear translocation of Nrf2 in the testis of OAS rats. AG can alleviate OAS via promoting nuclear translocation of Nrf2 and inhibiting ferroptosis of testis.

Induction of macroautophagy/autophagy has been established as an important function elicited by the CGAS-STING1 pathway during pathogen infection. However, it remains unknown whether lysosomal activity within the cell in these settings is concurrently enhanced to cope with the increased autophagic flux. Recently, we discovered that the CGAS-STING1 pathway elevates the degradative capacity of the cell by activating lysosome biogenesis.

Neuroblastoma (NB) is a rare embryonal neuroendocrine tumor that primarily affects children aged 5 years old or younger. In advanced stages, NB requires a multifaceted treatment approach, including a combination of surgery, chemo, and radiation therapy. However, high-risk NB is still associated with poor prognosis, long-term side effects, and a high chance of relapse.

The trimeric intracellular cation channel B (TRIC-B), encoded by TMEM38B, is a potassium (K) channel present in the endoplasmic reticulum membrane, where it counterbalances calcium (Ca) exit. Lack of TRIC-B activity causes a recessive form of the skeletal disease osteogenesis imperfecta (OI), namely OI type XIV, characterized by impaired intracellular Ca flux and defects in osteoblast (OB) differentiation and activity. Taking advantage of the OB-specific Tmem38b knockout mouse (Runx2Cre;Tmem38b; cKO), we investigated how the ion imbalance affects the osteogenetic process.

Neuroinflammation, a significant contributor to various neurodegenerative diseases, is strongly associated with the aging process; however, to date, no efficacious treatments for neuroinflammation have been developed. In aged mouse brains, the number of infiltrating immune cells increases, and the key transcription factor associated with increased chemokine levels is nuclear factor kappa B (NF-κB). Exosomes are potent therapeutics or drug delivery vehicles for various materials, including proteins and regulatory genes, to target cells.

Despite advances in gastric cancer diagnosis and treatment, its prognosis remains poor owing to aggressive tumor progression and metastasis. As understanding the relevant molecular mechanisms is essential to effectively improve patient outcomes, we elucidated the role of Kindlin-1 in gastric cancer progression and metastasis. Kindlin-1 expression was analyzed in 359 gastric cancer tissue samples provided by Kangnam Sacred Heart Hospital and publicly available GSE datasets.
