Objective:
Recent studies revealed that long non-coding RNAs (lncRNAs) participate in the progression and development of many human diseases. In this work, we are committed to uncovering the association between lncRNA MNX1-AS1 and the development of osteosarcoma.
Patients And Methods:
MNX1-AS1 expression of osteosarcoma cells and tissue samples was detected by Real Time-quantitative Polymerase Chain Reaction (RT-qPCR). Besides, we conducted functional assays including cell proliferation assay, colony formation, and transwell assays. Furthermore, the underlying mechanism including RT-qPCR and Western blot assay was performed.
Results:
MNX1-AS1 was higher-expressed in osteosarcoma samples than that in adjacent tissues. The abilities of proliferation and invasion were suppressed after MNX1-AS1 was knocked down in vitro. Moreover, KISS1 expression was upregulated at mRNA and protein level via silence of MNX1-AS1. Furthermore, the underlying mechanism of the development of osteosarcoma were investigated by RT-qPCR and Western blot assay.
Conclusions:
Our study demonstrated that MNX1-AS1 could enhance osteosarcoma cell proliferation and invasion by inhibiting KISS1, which might contribute to the therapy for osteosarcoma.
Insights
Long non-coding RNA MNX1-AS1 promotes osteosarcoma development by enhancing cell proliferation and invasion. Inhibiting MNX1-AS1 upregulates KISS1, offering a potential therapeutic target for osteosarcoma.
Area of Science:
- Molecular biology
- Oncology
- Genetics
Background:
- Long non-coding RNAs (lncRNAs) are implicated in human disease progression.
- The role of lncRNA MNX1-AS1 in osteosarcoma development requires further investigation.
Purpose of the Study:
- To elucidate the association between lncRNA MNX1-AS1 and osteosarcoma.
- To explore the functional role and underlying mechanism of MNX1-AS1 in osteosarcoma.
Main Methods:
- MNX1-AS1 expression was quantified in osteosarcoma tissues and cells using RT-qPCR.
- Functional assays (proliferation, colony formation, Transwell) were performed after MNX1-AS1 knockdown.
- Mechanism investigation involved RT-qPCR and Western blot to assess KISS1 expression.
Main Results:
- MNX1-AS1 was significantly upregulated in osteosarcoma tissues compared to adjacent tissues.
- Knockdown of MNX1-AS1 suppressed osteosarcoma cell proliferation and invasion in vitro.
- Silencing MNX1-AS1 led to the upregulation of KISS1 at both mRNA and protein levels.
Conclusions:
- MNX1-AS1 promotes osteosarcoma cell proliferation and invasion.
- MNX1-AS1 exerts its effects by inhibiting KISS1.
- Targeting MNX1-AS1 may represent a potential therapeutic strategy for osteosarcoma.
