Transcriptomic profiling of HCT116 and HT29 colorectal cancer cells after piR-37524 inhibition

ABSTRACT: Piwi-interacting RNA 37524 (piR-37524) is a novel oncogenic non-coding RNA overexpressed in colorectal cancer (CRC), associated with tumor progression, metastasis, and poor clinical outcomes. To elucidate the downstream transcriptional regulatory network of piR-37524, we performed RNA sequencing on two human CRC cell lines (HCT116 and HT29) transfected with a piR-37524-specific inhibitor or negative control (NC). Total RNA was extracted 48 hours post-transfection, and libraries were sequenced on an Illumina HiSeq 2500 platform. KEGG enrichment analysis revealed DEGs were significantly associated with TNF signaling pathway, TGF-beta signaling pathway, and microRNAs in cancer which are key pathways involved in CRC cell proliferation, migration, and epithelial-mesenchymal transition. Intersection analysis of upregulated DEGs across both cell lines identified TNFAIP3 as a potential direct target of piR-37524. This transcriptomic dataset provides comprehensive insights into the gene regulatory network mediated by piR-37524 in CRC cells, supporting its role as a therapeutic target via the TNFAIP3/NF-κB/EMT axis. The data will facilitate further exploration of piRNA-driven oncogenic mechanisms in CRC and the development of novel diagnostic or therapeutic strategies.

Transcriptome analysis of novel CPT-CEF-treated HT29 colon cancer cells to evaluate drug cytotoxicity

Project description:Purpose: To identify differentially expressed genes in HT29 colon cancer cells after treatment with a novel formulation of camptothecin with β-cyclodextrin-EDTA-Fe3O4 nanoparticle-conjugated nanocarriers (CPT-CEF) Methods:Treated HT29 cell lines with CPT-CEF, isolated total RNA from HT29 colon cancer cells, and prepared library for RNA sequencing. Carried out comparative transcriptomic studies between treated and untreated cells to find out which gene functions were dysregulated by CPT-CEF. Results: The study yielded 247 DEGs ((FDR<0.05, FC>2.0) that were affected by CPT-CEF treatment in the HT29 colon cancer cells. The results obtained from cell cycle analysis, mitochondrial depolarization assay and acridium orange/propidium iodide double staining showed potential of CPT-CEF in cancer cell inhibition. Conclusion: Our study successfully identified DEGs in the CPT-CEF treated HT29 colon cancer cells that pointed to inhibition of cancer progression. To further affirm, animal studies are needed.

piR-36249 and DHX36 together inhibit testicular cancer cell progression by upregulating OAS2

Project description:PIWI-interacting RNAs (piRNAs) have been identified in mammalian germline initially and later also found to be aberrantly expressed in various cancers. However, their functions in cancer is not very clear. Here, we studied the role of piR-36249, a member of the piRNA family, in testicular cancer. We show that piR-36249 is significantly downregulated in testicular cancer tissues comparing to tumor-adjacent tissues. Functional studies demonstrate that piR-36249 inhibits testicular cancer cell proliferation, migration and invasion. Mass Spectrometry (MS) analysis of piR-36249 pull-downed proteins reveals that piR-36249 interacts with ATP-dependent DNA/RNA helicase (DHX36). Dual-luciferase assays shows that piR-36249 binds to the 3'UTR of 2'-5'-oligoadenylate synthetase 2 (OAS2) mRNA. OAS2 has been shown in literature as a tumor suppressor modulating the occurrence and development of some tumors, such as colorectal cancer and breast cancer. In this study, OAS2 knockdown also promotes testicular cancer cell proliferation and migration. Furthermore, RNA immunoprecipitation assay reveals that DHX36 can also bind to OAS2 mRNA, and knockdown of DHX36 increases OAS2 mRNA yet downregulates its protein, indicating the enhancing OAS2 protein expression level effect of DHX36. All these data suggest that piR-36249, together with DHX36, functions in inhibiting testicular cancer cells proliferation, migration and invasion by upregulating OAS2 protein, and piR-36249 may serve as a potential predictor for the prognosis of testicular cancer.

Gene expression profiling of IL7R+PIR+ and IL7R-PIR- subsets in LIN-c-Kit+ E12.5 mouse fetal liver cells

Project description:In order to find out taget genes of Runx/Cbfb2 complexes in PIR+IL7R+ subset. In particular, genes that would explain why the size of thymus was small by lack of Cbfb2. Upon finding of decresed IL7R+PIR+ subset, which was reported as thymus-homing progenitor, in Cbfb2 deficient embruos embryos, we focused on these population.

Identification of Liver Receptor Homologue-1 (LRH-1)-regulated genes in HT29 colorectal cancer cells

Project description:Liver receptor homologue 1 (LRH-1) is an orphan nuclear receptor which has been implicated in the growth and development of breast, pancreatic and colorectal cancers (CRC). In order to identify novel LRH-1-regulated genes in CRC cells, we performed gene expression profiling following siRNA-mediated LRH-1 silencing in the CRC cell line HT29.

The RNA phosphatase PIR-1 regulates endogenous small RNA pathways in C. elegans

Project description:Eukaryotic cells regulate 5’ triphosphorylated (ppp) RNAs to promote cellular functions and to prevent recognition by viral RNA sensors. For example, the triphosphatase domain of RNA capping enzymes removes the γ phosphate of ppp-RNAs in RNA capping reactions. Members of a related RNA polyphosphotase family including human PIR1 remove both the β and γ phosphates from ppp-RNAs. Here we demonstrate that C. elegans PIR-1, previously identified as a Dicer-interacting protein, dephosphorylates single and double-stranded ppp-RNAs, and is required for the maturation of 26G-RNAs, which regulate thousands of genes during spermatogenesis and embryogenesis. We find that 26G-RNAs are generated in a unique semi-phasing manner in which primary 26G-RNAs are required for generating secondary 26G-RNAs and PIR-1 is required for removing a diphosphate group from each triphosphorylated precursor, which only generates one 26G-RNA. Our findings also implicate PIR-1 in regulating ppp-RNAs in Dicer-independent pathways, supporting PIR-1 as a master phosphatase regulating ppp-RNAs.

PiR-hsa-4447944 serves as an oncogenic mediator in prostate cancer and promotes the development of castration resistance by inhibiting NEFH expression

Project description:PiR-hsa-4447944 showed a significantly higher expression level in both CRPC tissues and CRPC cell lines. Functionally, piR-hsa-4447944 overexpression conferred, whereas piR-hsa-4447944 suppression inhibited castration resistance ability in vitro and in vivo. Enforced piR-hsa-4447944 expression in vitro promoted PCa cells migration and invasion, as well as reduced cell apoptosis. To explore the potential targets of piR-hsa-4447944, two PCa cells 22RV1 and LNCaP were transfected with control or piR-hsa-4447944 mimic, and then the extracted total RNA was used for mRNA sequencing and bioinformatic analysis.
