Biological Activity of Senexin A

DescriptionSenexin A is a CDK8 inhibitor with an IC50 of 280 nM.In Vitro:Senexin A inhibits CDK8 and CDK19 ATP site binding with Kd50 of 0.83 μM and 0.31 μM, respectively and CDK8 kinase activity with IC50 of 0.28 μM. Senexin A inhibits β-catenin–dependent transcription in HCT116 colon carcinoma cells. The induction of transcription factor EGR1 upon serum starvation, followed by readdition of serum, is strongly inhibited by Senexin A in HT1080 cells. Senexin A inhibits only p21-induced transcription but not other biological effects of p21. Senexin A also decreases the expression of many secreted tumor-promoting factors in doxorubicin-treated wild-type HCT116 cells[1].In Vivo:Five daily treatment of Senexin A fully reverses tumor-promoting effect of chemotherapy. Senexin A shows no detectable toxicity and no significant effects on body weight, organ weights, or blood cell counts in C57BL/6 mice during the treatment. This effect of doxorubicin treatment is completely abolished, however, when doxorubicin injection is followed by administration of Senexin A. Senexin A treatment strongly improves the response of A549/MEF tumors to doxorubicin[1].

Protocol

Animal Administration [1]
Mice: Senexin A toxicity study is conducted by Taconic in C57BL/6 mice, using five mice per group treated with 20 mg/kg Senexin A or carrier (80% propylene glycol), with five daily i.p. injections. Mice are weighed on days 3 and 6, and killed on day 6. Organ weights are determined for brain, kidney, thymus, spleen, lung, and liver. Terminal blood samples are analyzed to determine the numbers of total white blood cells, neutrophils, lymphocytes, monocytes, eosinophils, and basophils[1].

Background on Senexin A

IC50: 280 nM

Senexin A is a Cyclin-dependent kinase 8 (CDK8) inhibitor.

CDK8 is an oncogenic CDK family member that plays no role in cell-cycle progression but regulates several transcriptional programs involved in carcinogenesis and the stem-cell phenotype. CDK8 also cooperates in the formation of internucleolar bodies, where CDK8 accumulates.

In vitro: Senexin A inhibited p21-caused induction of CMV-GFP when GFP expression was normalized either by relative cell number or by the protein amount. p21 was shown to activate NF-κB–dependent transcription, and Senexin A could inhibit p21-stimulated activity of the consensus NF-κB–dependent promoter. Senexin A had no effect on p21 induction by IPTG, on p21-induced senescent phenotype, or on cell growth with or without p21 [1].

In vivo: Previous study tested Senexin A combined with MEF for the in vivo chemosensitization of xenografts formed by tumor cells. SCID mice were injected with A549 cells mixed with MEF. Once tumors stably formed, mice were treated by a single injection of doxorubicin, with five daily injections of either vehicle or Senexin A. Results showed that Senexin A treatment strongly improved the response of A549/MEF tumors to doxorubicin [1].

CDK8 Kinase Activity Promotes Glycolysis.[Pubmed:29117556]

Cell Rep. 2017 Nov 7;21(6):1495-1506.

Aerobic glycolysis, also known as the Warburg effect, is a hallmark of cancerous tissues. Despite its importance in cancer development, our understanding of mechanisms driving this form of metabolic reprogramming is incomplete. We report here an analysis of colorectal cancer cells engineered to carry a single point mutation in the active site of the Mediator-associated kinase CDK8, creating hypomorphic alleles sensitive to bulky ATP analogs. Transcriptome analysis revealed that CDK8 kinase activity is required for the expression of many components of the glycolytic cascade. CDK8 inhibition impairs glucose transporter expression, glucose uptake, glycolytic capacity and reserve, as well as cell proliferation and anchorage-independent growth, both in normoxia and hypoxia. Importantly, CDK8 impairment sensitizes cells to pharmacological glycolysis inhibition, a result reproduced with Senexin A, a dual inhibitor of CDK8/CDK19. Altogether, these results contribute to our understanding of CDK8 as an oncogene, and they justify investigations to target CDK8 in highly glycolytic tumors.
