CDK11 Promotes Cytokine-Induced Apoptosis in Pancreatic Beta Cells Independently of Glucose Concentration and Is Regulated by Inflammation in the NOD Mouse Model. Front Immunol 2021; 12:634797. [PMID: 33664748 PMCID: PMC7923961 DOI: 10.3389/fimmu.2021.634797] [Citation(s) in RCA: 2] [Impact Index Per Article: 0.7] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 11/28/2020] [Accepted: 01/07/2021] [Indexed: 11/13/2022] Open
Abstract
Background Pancreatic islets are exposed to strong pro-apoptotic stimuli: inflammation and hyperglycemia, during the progression of the autoimmune diabetes (T1D). We found that the Cdk11(Cyclin Dependent Kinase 11) is downregulated by inflammation in the T1D prone NOD (non-obese diabetic) mouse model. The aim of this study is to determine the role of CDK11 in the pathogenesis of T1D and to assess the hierarchical relationship between CDK11 and Cyclin D3 in beta cell viability, since Cyclin D3, a natural ligand for CDK11, promotes beta cell viability and fitness in front of glucose. Methods We studied T1D pathogenesis in NOD mice hemideficient for CDK11 (N-HTZ), and, in N-HTZ deficient for Cyclin D3 (K11HTZ-D3KO), in comparison to their respective controls (N-WT and K11WT-D3KO). Moreover, we exposed pancreatic islets to either pro-inflammatory cytokines in the presence of increasing glucose concentrations, or Thapsigargin, an Endoplasmic Reticulum (ER)-stress inducing agent, and assessed apoptotic events. The expression of key ER-stress markers (Chop, Atf4 and Bip) was also determined. Results N-HTZ mice were significantly protected against T1D, and NS-HTZ pancreatic islets exhibited an impaired sensitivity to cytokine-induced apoptosis, regardless of glucose concentration. However, thapsigargin-induced apoptosis was not altered. Furthermore, CDK11 hemideficiency did not attenuate the exacerbation of T1D caused by Cyclin D3 deficiency. Conclusions This study is the first to report that CDK11 is repressed in T1D as a protection mechanism against inflammation-induced apoptosis and suggests that CDK11 lies upstream Cyclin D3 signaling. We unveil the CDK11/Cyclin D3 tandem as a new potential intervention target in T1D.

Abstract
Cyclin proteins are the key regulatory and activity partner of cyclin-dependent kinases (CDKs), which play pivotal regulatory roles in cell cycle progression. In the present study, we identified a Cyclin L1 and 2 CDK11 2 CDK11 splice variants, CDK11A and CDK11B, from silkworm, Bombyx mori. We determined that both Cyclin L1 and CDK11A/B are nuclear proteins, and further investigations were conducted to elucidate their spatiofunctional features. Cyclin L1 forms a complex with CDK11A/B and were co-localized to the nucleus. Moreover, the dimerization of CDK11A and CDK11B and the effects of Cyclin L1 and CDK11A/B on cell cycle regulation were also investigated. Using overexpression or RNA interference experiments, we demonstrated that the abnormal expression of Cyclin L1 and CDK11A/B leads to cell cycle arrest and cell proliferation suppression. Together, these findings indicate that CDK11A/B interacts with Cyclin L1 to regulate the cell cycle.

Abstract
Uncontrolled proliferation is the hallmark of cancer and other proliferative disorders and abnormal cell cycle regulation is, therefore, common in these diseases. Cyclin-dependent kinases (CDKs) play a crucial role in the control of the cell cycle and proliferation. These kinases are frequently deregulated in various cancers, viral infections, neurodegenerative diseases, ischemia and some proliferative disorders. This led to a rigorous pursuit for small-molecule CDK inhibitors for therapeutic uses. Early efforts to block CDKs with nonselective CDK inhibitors led to little specificity and efficacy but apparent toxicity, but the recent advance of selective CDK inhibitors allowed the first successful efforts to target these kinases for the therapies of several diseases. Major ongoing efforts are to develop CDK inhibitors as monotherapies and rational combinations with chemotherapy and other targeted drugs.

Abstract
In response to a variety of neural damages in the CNS, quiescent astrocytes become reactive astrocytes. Astrocytes are the major glial subtype and are important effectors that participate in the pathogenesis of numerous neural disorders, including trauma, stroke, aging, and developmental, genetic, idiopathic or acquired neurodegenerative diseases. CDK11(p58) (Cyclin-dependent kinases 11 protein 58/PITSLRE) is a p34cdc2-related protein kinase that plays an important role in normal cell cycle progression. In the process of LPS stimulus, the expression of CDK11(p58) in astrocytes was increased. Induced CDK11(p58) was parallel to astrocyte inflammatory response. Knockdown of CDK11(p58) by small-interfering RNAs (siRNAs) reduced the LPS-induced astrocyte inflammatory response, while overexpression CDK11(p58) enhanced the process. CDK11(p58) exerted its functions via activating p38 and JNK MAPK pathways. This study delineates that CDK11(p58) may be a significant regulatory factor for host defenses in central nervous system (CNS) inflammation.

Abstract
Dyregulated behavior of cell cycle proteins and their control by ubiquitin E3 ligases is an emerging theme in human lung cancer. Here we identified and characterized the activity of a novel F box protein, termed FBXL2, belonging to the SCF (Skip-Cullin1-F-box protein) E3 ligase family. Ectopically expressed FBXL2 triggered G2/M phase arrest, induced chromosomal anomalies, and increased apoptosis of transformed lung epithelia by mediating polyubiquitination and degradation of the mitotic regulator, cyclin D3. Unlike other F box proteins that target phosphodegrons within substrates, FBXL2 uniquely recognizes a canonical calmodulin-binding motif within cyclin D3 to facilitate its polyubiquitination. Calmodulin bound and protected cyclin D3 from FBXL2 by direct intermolecular competition with the F box protein for access within this motif. The chemotherapeutic agent vinorelbine increased apoptosis of human lung carcinoma cells by inducing FBXL2 expression and cyclin D3 degradation, an effect accentuated by calmodulin knockdown. Depletion of endogenous FBXL2 stabilized cyclin D3 levels, accellerated cancer cell growth, and increased cell viability after vinorelbine treatment. Last, ectopic expression of FBXL2 significantly inhibited the growth and migration of tumorogenic cells and tumor formation in athymic nude mice. These observations implicate SCFFBXL2 as an indispensible regulator of mitosis that serves as a tumor suppressor.

Abstract
Mitotic progression is regulated by ubiquitin E3 ligase complexes to carefully orchestrate eukaryotic cell division. Here, we show that a relatively new E3 ligase component belonging to the SCF (Skip-Cullin1-F-box protein) E3 ligase family, SCF (FBXL2) , impairs cell proliferation by mediating cyclin D3 polyubiquitination and degradation. Both cyclin D3 and FBXL2 colocalize within the centrosome. FBXL2 overexpression led to G 2/M-phase arrest in transformed epithelia, resulting in the appearance of supernumerary centrosomes, tetraploidy and nuclei where condensed chromosomes are arranged on circular monopolar spindles typical of mitotic arrest. RNAi-mediated knockdown of cyclin D3 recapitulated effects of SCF (FBXL2) expression. SCF (FBXL2) impaired the ability of cyclin D3 to associate with centrosomal assembly proteins [Aurora A, polo-like kinase 4 (Plk4), CDK11]. Thus, these results suggest a role for SCF (FBXL2) in regulating the fidelity of cellular division.
