Abstract

Colorectal Cancer (CRC) is a critical global health challenge and ranks third among commonly diagnosed malignancies worldwide. As a Cancer related long-noncoding RNA (lncRNA), Jumonji C domain containing Histone Demethylase 1 homolog D antisense 1 (JHDM1D-AS1) is analyzed to be differentially expressed in CRC samples according to bioinformatics analysis. This study aimed to further explore its effects on CRC cellular process and tumor growth as well as the related mechanisms. Quantitative polymerase chain reaction (RT-qPCR) was utilized to assess expression levels of JHDM1D-AS1 and its downstream molecules in CRC tissues and cells. Functional assays, including colony formation, wound healing, and Transwell assays, were performed to evaluate cellular processes such as proliferation, migration, and invasion. In vivo xenograft and metastasis models were established to examine tumor growth and liver metastasis. The subcellular distribution of JHDM1D-AS1 in CRC cells was measured using fluorescence in situ hybridization (FISH). RNA pulldown and luciferase reporter assays were conducted to confirm molecular interactions. HPRT1 protein expression was quantified using Western blotting. JHDM1D-AS1 is significantly upregulated in CRC cells. Knockdown of JHDM1D-AS1 suppresses CRC cell proliferation, migration, and invasion as well as xenograft tumor growth. JHDM1D-AS1 interacts with miR-193b-3p to regulate HPRT1 expression. MiR-193b-3p targets and downregulates HPRT1. Overexpression of HPRT1 reverses the suppressive effects caused by JHDM1D-AS1 depletion on CRC cell malignancy. In conclusion, JHDM1D-AS1 promotes CRC cell proliferation, metastasis, invasion and tumor development by upregulating HPRT1 expression via miR-193b-3p.
