Article Abstract

Cyclin-dependent kinase 9 (CDK9), a member of the cyclin-dependent protein kinase (CDK) family, is involved in transcriptional elongation of several target genes. CDK9 is ubiquitously expressed and has been shown to contribute to a variety of malignancies such as pancreatic, prostate and breast cancers. Here we report the development of a heterobifunctional small molecule proteolysis targeting chimera (PROTAC) capable of cereblon (CRBN) mediated proteasomal degradation of CDK9. In HCT116 cells, it selectively degrades CDK9 while sparing other CDK family members. This is the first example of a PROTAC that selectively degrades CDK9.

Despite advancements in EGFR- and KRAS-targeted therapies for lung adenocarcinoma (LUAD), novel targets are needed for patients unresponsive or resistant to current treatments. This study demonstrates the critical role of CREPT in modulating ERK-downstream gene transcription in LUAD progression. CREPT expression and function were investigated using human LUAD tissues, EGFR/KRAS mutant LUAD cell lines, and mouse models.

A CDK11-dependent RNA polymerase II pause-checkpoint precedes CDK9-mediated transition to transcriptional elongation.

Controlled gene expression is achieved through the intricate regulation of RNA polymerase II (Pol II) progression through transcription-cycle checkpoints. While the contribution of CDK9 for Pol II pause-release is well established, the requirement for other cyclin-dependent kinases (CDKs) has not been fully elucidated. In this study, we propose a critical role for CDK11 in the Pol II pausing-to-elongation transition at a checkpoint that precedes and is independent from CDK9.

Background: Cholesterol metabolism plays a significant role in cancer progression, including prostate adenocarcinoma (PRAD), making it a promising target for therapeutic intervention. This study aimed to construct and validate a cholesterol metabolism gene (CMG)-related prognostic signature to predict prognosis in PRAD patients, while exploring its biological, clinical, and therapeutic implications.

Methods: CMGs were retrieved through comprehensive searches in public databases.

CLL is the most prevalent adult leukemia in Western countries, characterized by the accumulation of monoclonal B lymphocytes. Over the past decade, the therapeutic landscape for CLL has undergone significant transformations, primarily due to the introduction of targeted small molecular therapies like BTK inhibitors and BCL-2 inhibitors, that have improved patient outcomes drastically. Despite significant advances, long-term disease management remains challenging for patients with double-refractory CLL, where responses with subsequent therapies are short-lived.

Kelch-like ECH-associated protein 1 (KEAP1) functions as a substrate adaptor for the Cullin 3-RING E3 ligase complex, mediating the ubiquitination and subsequent proteasomal degradation of nuclear factor erythroid 2-related factor 2 (NRF2). This regulatory mechanism maintains cellular redox homeostasis by preventing NRF2 overactivation. Proteolysis-targeting chimeras (PROTACs) have emerged as a novel therapeutic strategy that harnesses the ubiquitin-proteasome system for targeted protein degradation.
