Abstract:
In this study, we intended to figure out the biological significance of long non-coding RNAs (lncRNAs) solute carrier organic anion transporter family member 4A1 antisense RNA 1 (SLCO4A1-AS1) in pancreatic cancer (PC). Cell counting kit-8, colony formation, wound healing, transwell, and flow cytometry experiments were performed to reveal how SLCO4A1-AS1 influences PC cell proliferation, migration, invasion, and apoptosis. Thereafter, bioinformatics analysis, RNA immunoprecipitation assay, luciferase reporter assay, and RNA pull-down assay were applied for determining the binding sites and binding capacities between SLCO4A1-AS1 and miR-4673 or kinesin family member 21B (KIF21B) and miR-4673. The results depicted that SLCO4A1-AS1 was upregulated in PC, and SLCO4A1-AS1 knockdown suppressed PC cell growth, migration, invasion, and induced cell apoptosis. Furthermore, SLCO4A1-AS1 was verified to modulate the expression of KIF21B by binding with miR-4673. SLCO4A1-AS1 exerted an oncogenic function in PC. The overexpression of SLCO4A1-AS1 aggravated the malignant behaviors of PC via the upregulation of KIF21B by sponging miR-4673. Our findings revealed a novel molecular mechanism mediated by SLCO4A1-AS1, which might play a significant role in modulating the biological processes of PC.
Insights
Long non-coding RNA SLCO4A1-AS1 promotes pancreatic cancer (PC) progression by upregulating KIF21B via sponging miR-4673. Knockdown of SLCO4A1-AS1 inhibits PC cell growth, migration, and invasion, while promoting apoptosis.
Area of Science:
- Molecular Biology
- Oncology
- Genetics
Background:
- Pancreatic cancer (PC) remains a significant health challenge with limited therapeutic options.
- Long non-coding RNAs (lncRNAs) are increasingly recognized for their roles in cancer development.
- The specific function of lncRNA SLCO4A1-AS1 in PC is not well understood.
Purpose of the Study:
- To elucidate the biological significance and molecular mechanism of lncRNA SLCO4A1-AS1 in pancreatic cancer.
- To investigate the role of SLCO4A1-AS1 in regulating PC cell proliferation, migration, invasion, and apoptosis.
Main Methods:
- Cell proliferation, migration, invasion, and apoptosis assays (CCK-8, colony formation, wound healing, Transwell, flow cytometry).
- Bioinformatics analysis, RNA immunoprecipitation (RIP), luciferase reporter assays, and RNA pull-down assays.
- Investigation of the interaction between SLCO4A1-AS1, miR-4673, and KIF21B.
Main Results:
- SLCO4A1-AS1 expression was significantly upregulated in pancreatic cancer tissues and cell lines.
- Knockdown of SLCO4A1-AS1 suppressed PC cell proliferation, migration, and invasion, and induced apoptosis.
- SLCO4A1-AS1 directly binds to miR-4673, acting as a molecular sponge, and upregulates KIF21B expression.
Conclusions:
- SLCO4A1-AS1 functions as an oncogenic lncRNA in pancreatic cancer.
- The SLCO4A1-AS1/miR-4673/KIF21B axis plays a critical role in promoting pancreatic cancer progression.
- SLCO4A1-AS1 represents a potential therapeutic target for pancreatic cancer treatment.
