Integrated omics profiling reveals FOXA1 and Ku70/Ku80 as the direct target of ivermectin for prostate carcinogenic inhibition

ABSTRACT: Here, we show that ivermectin suppress prostate cancer progression by inhibiting AR signaling pathway and attenuate cellular DNA damage repair capacity. We applied an integrated omics profiling including RNA-seq and Thermal proteome, that found pioneer factor Forkhead Box Protein A1 (FOXA1) and Non-homologous End Joining (NHEJ) repair executer Ku70/Ku80 was the direct target of Ivermectin in prostate cancer. Ivermectin binds to these two proteins and block their biological function, which results in blockade of AR signaling transcription and deficiency of DNA double-strand breaks (DSBs) repair system, and thereby leads to G0/G1 arrest and trigger synthetic lethality Our findings demonstrate both the effect and target of Ivermectin in prostate cancer comprehensively and systemically, indicating that use of Ivermectin may constitute a new therapeutic approach for prostate cancer.

Transcriptome data for HEK293T cells depleted of one subunit of DNA-PK complex: Ku70, Ku80 or DNA-PKcs.

Project description:DNA-PK is a heterotrimeric complex that consists of Ku70 (XRCC6), Ku80 (XRCC5) and DNA-PKcs (PRKDC) subunits. DNA-PK complex is a major player in DNA double strand break (DSB) repair via non-homologous end joining pathway. This process requires all of DNA-PK subunits. Ku70/Ku80 heterodimers firstly bind to DNA-ends at DSB, that increase affinity of DNA-PKcs to DNA-ends. Recruitment of DNA-PKcs subunit to DSB leads to phosphorylation events near DSB, recruitment of another NHEJ-related genes that restore DNA integrity. However, today a lot of evidence demonstrate participation of DNA-PK components in other cellular process, e.g. cytosolic DNA sensing, apoptosis regulation, cellular movement and adhesion. It is important to note that not all subunits of DNA-PK complex are necessary for these process. This demonstrate the independent functions of DNA-PK subunits. Here we for the first time using NGS-sequencing analyzed the transcriptional changes in HEK293T cells under depletion of Ku70, Ku80 or DNA-PKcs to characterize the independent functions of each subunit.

CircPRKAA1 activates a Ku80/Ku70/SREBP1 axis driving de novo fatty acid synthesis in cancer cells

Project description:Many metabolism-related genes undergo alternative splicing to generate circular RNAs although their functions remain poorly understood. Here we report that circPRKAA1, a circRNA derived from the α1 subunit of AMPK, fulfils a fundamental role in maintaining lipid homeostasis. CircPRKAA1 expression facilitates fatty acid synthesis and promotes lipid storage through two coordinated functions. First, circPRKAA1 promotes a tetrameric complex between the Ku80/Ku70 heterodimer and the mature form of sterol regulatory element-binding protein-1 (mSREBP1) to enhance the stability of mSREBP1. Secondly, circPRKAA1 selectively binds to the promoters of the ACC1, ACLY, SCD1 and FASN genes to recruit mSREBP1, upregulating their transcription and increasing fatty acid synthesis to promote cancer growth. Moreover, circPRKAA1 biogenesis is negatively regulated by AMPK activity with lower AMPK activation in hepatocellular carcinoma tissues frequently associated with elevated circPRKAA1 expression. Together, this work identifies circPRKAA1 as an integral element of AMPK-regulated reprogramming of lipid metabolism in cancer cells.

Host gene expression response to Toxoplasma gondii infection is not different between RH?ku80 and RH?ku80?rop5 parasites.

Project description:The normally virulent type-I RH parasite is rendered avirulent when lacking ROP5. The avirulent phenotype is a consequence of interaction with the host innate immune system. We sought to understand if ROP5 alters host gene expression in order to escape host defenses. We saw no gene expression differences between host cells infected with wt (RH?ku80) or RH?ku80?rop5 parasites. We have included uninfected HFF samples that were harvested in parallel with the infected samples. Host gene expression in response to infection with Toxoplasma gondii. Two independent samples per sample type. Three sample types: HFF infected with RH?ku80, HFF infected with RH?ku80?rop5, and uninfected HFF.

Expression data from Caenorhabditis elegans exposed to ivermectin

Project description:We have investigated the transcriptomic response of the model nematode Caenorhabditis elegans to ivermectin (IVM); an important anthelmintic for human and animal parasite control. The transcriptomic response of the mutant strain DA1316 avr-14(ad1302); avr-15(ad1250); glc-1(pk54), which is highly resistant to ivermectin due to null mutations in three glutamate-gated chloride channel subunits, was examined. Despite the resistant nature of this strain, pharyngeal pumping rate was decreased following 4 hrs exposure to 100ng/ml and 1?g/ml ivermectin resulting in significant change in the expression level of genes associated with a fasting response. Matched cultures of synchronised C. elegans were grown to L4 stage on standard NGM plates with an OP50 bacterial lawn. The nematodes were then transferred to NGM plates containing 100ng/ml ivermectin, 1?g/ml ivermectin, or DMSO excipient only (control) for 4 hours. RNA was extracted from five biological replicates including controls for both the 100ng/ml ivermectin and 1?g/ml ivermectin experiments and hybridised to Affymetrix arrays.

Genome-wide analysis of AR-responsive gene expression in prostate cancer cells

Project description:Analysis of AR-regulation of gene expression. The hypothesis tested in the present study was that AR influences the expression of genes that participate in important bioprocesses in prostate cancer cells, including cell cycle, DNA replication, recombination and repair. Results provide important information on AR-responsive genes that may be crucial to the cell survival and the progression of prostate cancer. Total RNA obtained from AR siRNA-transfected prostate cancer cells compared to negative control siRNA-transfected prostate cancer cells 48 h after siRNa transfection.
