AI Article Synopsis

  • lncRNA, specifically HIF1A-AS2, is found to be upregulated in colorectal cancer (CRC) tissues, linking it to poor patient outcomes and tumor development.
  • HIF1A-AS2 promotes cancer cell proliferation, metastasis, and a shift to aerobic glycolysis by influencing the expression of FOXC1 through direct interaction with miR-141-3p.
  • The study suggests that HIF1A-AS2, regulated by SP1 and also packaged in exosomes, could serve as a valuable diagnostic marker and a potential target for CRC treatments.

Article Abstract

lncRNA can regulate tumorigenesis development and distant metastasis of colorectal cancer (CRC). However, the detailed molecular mechanisms are still largely unknown. Using RNA-sequencing data, RT-qPCR, and FISH assay, we found that HIF1A-AS2 was upregulated in CRC tissues and associated with poor prognosis. Functional experiments were performed to determine the roles of HIF1A-AS2 in tumor progression and we found that HIF1A-AS2 can promote the proliferation, metastasis, and aerobic glycolysis of CRC cells. Mechanistically, HIF1A-AS2 can promote FOXC1 expression by sponging miR-141-3p. SP1 can transcriptionally activate HIF1A-AS2. Further, HIF1A-AS2 can be packaged into exosomes and promote the malignant phenotype of recipient tumor cells. Taken together, we discovered that SP1-induced HIF1A-AS2 can promote the metabolic reprogramming and progression of CRC via miR-141-3p/FOXC1 axis. HIF1A-AS2 is a promising diagnostic marker and treatment target in CRC.

Dysregulation of lncRNAs is a critical factor in the migration and invasion of tumors. Here our study reveals that lncRNA HIF1A-AS2 is highly expressed in breast cancer tissues and various TNBC cell lines. Moreover, we present compelling evidence supporting the role of HIF1A-AS2 in promoting TNBC cell proliferation, metastasis, invasion, and resistance to paclitaxel treatment.

Intratumoral hypoxia not only promotes angiogenesis and invasiveness of cancer cells but also creates an immunosuppressive microenvironment that facilitates tumor progression. However, the mechanisms by which hypoxic tumor cells disseminate immunosuppressive signals remain unclear. In this study, we demonstrate that a hypoxia-induced long noncoding RNA HIF1A Antisense RNA 2 (HIF1A-AS2) is upregulated in hypoxic tumor cells and hypoxic tumor-derived exosomes in head and neck squamous cell carcinoma (HNSCC).

Article Synopsis
  • Clear cell renal cell carcinoma (ccRCC) is a common type of kidney cancer that can be influenced by certain RNA molecules called long non-coding RNAs (lncRNAs).
  • The study looked at a specific lncRNA named HIF1A-AS2 to see how it affects ccRCC cells by promoting their growth and influencing other important proteins.
  • The findings suggest that targeting HIF1A-AS2 could lead to new treatments for ccRCC by stopping the growth of cancer cells.

The aim of this study was to explore the role and mechanism of long non-coding RNA (lncRNA) HIF1A antisense RNA 2 (HIF1A-AS2) in regulating imatinib (IM) resistance in gastrointestinal stromal tumor (GIST) cells under hypoxia. The expression of HIF1A-AS2 was silenced by siRNA in GIST cells. Cytotoxicity, apoptosis, and autophagy were evaluated under normoxic and hypoxic conditions.
