CRYAB is upregulated and predicts clinical prognosis in kidney renal clear cell carcinoma.

Clear cell renal cell carcinoma (KIRC) is the most prevalent subtype of renal cell carcinoma (RCC), accounting for 70% to 80% of all RCC cases. The CRYAB (αB-crystallin) gene is broadly expressed across various human tissues, yet its role in KIRC progression remains unclear. This study aims to elucidate the function of CRYAB in KIRC progression and to assess its potential as a biomarker for early diagnosis, therapeutic targeting, and prognosis.

Trends and Clinical Implications of Pediatric Pulmonary Function After Hematopoietic Stem Cell Transplantation: A Systematic Review.
