Targeting CK1δ and CK1ε as a New Therapeutic Approach for Clear Cell Renal Cell Carcinoma

Kidney cancer ranks as the ninth most common cancer in men and the fourteenth in women globally, with renal cell carcinoma (RCC) being the most prevalent type. Despite advances in therapeutic strategies targeting angiogenesis and immune checkpoints, the absence of reliable markers for patient selection and limited duration of disease control underline the need for innovative approaches. CK1δ and CK1ε are highly conserved serine/threonine kinases involved in cell cycle regulation, apoptosis, and circadian rhythm. While CK1δ dysregulation is reportedly associated with breast and bladder cancer progression, their role in RCC remains elusive. This study aims to investigate the feasibility of CK1δ/ε as new therapeutic targets for RCC patients.
