Department of Andrology, Dongzhimen Hospital, Beijing University of Chinese Medicine, Beijing, 100700, China.
Background And Aim: As a classical formula to invigorate blood circulation, Huoxue Tongluo Qiwei Decoction (HTQD) can effectively treat hypertensive erectile dysfunction (ED), but its exact mechanism of action is not yet clear. The goal of this research was to explore the potential mechanism of HTQD in improving hypertensive erectile dysfunction in rats through transcriptomics, network pharmacology, and associated animal experimentations.
Methods: The HTQD chemical constituents were screened using high-performance liquid chromatography- tandem mass spectrometry (HPLC-MS/MS).
Clinical implications of mineralocorticoid receptor overactivation.

The mineralocorticoid receptor (MR) is a nuclear transcription factor that plays a critical role in regulating fluid, electrolytes, blood pressure, and hemodynamic stability. In conditions such as chronic kidney disease (CKD) and heart failure (HF), MR overactivation leads to increased salt and water retention, inflammatory and fibrotic gene expression, and organ injury. The MR is essential for transcriptional regulation and is implicated in metabolic, proinflammatory, and pro-fibrotic pathways.

Clin Kidney J

Department of Medicine, Division of Nephrology, Samsung Medical Center, Sungkyunkwan University School of Medicine, Seoul, Republic of Korea.
Background: Although kidney biopsy is definitive for the diagnosis of acute interstitial nephritis (AIN) and acute tubular necrosis (ATN), its invasiveness limits its use. We aimed to identify urine biomarkers for differentiating AIN and ATN and to predict the response of patients with AIN to steroid treatment.
Methods: In this prospective cohort study, biopsy-proven ATN ( = 34) and AIN ( = 55) were included.
The positive feedback loop between SP1 and MAP2K2 significantly drives resistance to VEGFR inhibitors in clear cell renal cell carcinoma.

Clear cell renal cell carcinoma (ccRCC) is one of the most common and aggressive malignancies of the urinary system. Despite being the first-line treatment for advanced ccRCC, vascular endothelial growth factor receptor inhibitors (VEGFRis) face significant limitations due to both initial and acquired resistance, which impede complete tumor eradication. Using a CRISPR/Cas9 library screening approach, was identified as a resistance-associated gene for three prevalent VEGFRis (Sunitinib, Axitinib, and Sorafenib).

Cyclin D3 (CCND3), a member of the cyclin D family, is known to promote cell cycle transition. In this study, we found that CCND3 was downregulated in cisplatin-resistant (-diamminedichloroplatinum, DDP) lung adenocarcinoma (LUAD) cells. The loss of CCND3 indeed impeded cell cycle transition.
