KIAA1429 Promotes Osteosarcoma Growth
Osteosarcoma is a rare type of cancer that mostly affects children and adolescents. N6-methyladenosine (m6A) modification is a common form of RNA epigenetic modification, and previous studies have shown that it is involved in various diseases, including osteosarcoma. m6A regulators are abundant in osteosarcoma cells, suggesting that m6A modification may contribute to the progression of the disease.
Osteosarcoma is a rare type of cancer that mostly affects children and adolescents, and although survival rates have improved with chemotherapy, metastasis and recurrence remain major obstacles to effective treatment. N6-methyladenosine (m6A) modification is a common form of RNA epigenetic modification, and previous studies have shown that it is involved in various diseases, including osteosarcoma. m6A regulators, such as METTL3, MTTL14, WTAP, YTHDF1, and YTHDF2, are abundant in osteosarcoma cells, suggesting that m6A modification may contribute to the progression of the disease.
KIAA1429 is a protein involved in m6A modification, and has been shown to play a crucial role in the development of various types of cancer, including liver, breast, colorectal, lung, gastric, and ovarian cancer. Recent studies have also revealed that KIAA1429 is up-regulated in osteosarcoma patients, and is associated with poor prognosis. However, the exact role of KIAA1429 in osteosarcoma and its underlying mechanisms are still unclear, and further research is needed to explore its potential as a therapeutic target.
New Study: Methods & Results | Summed up
A recently published study aimed to investigate the role of KIAA1429 in osteosarcoma (OS). Human osteoblast and OS cell lines were cultured, and siRNA and overexpression vectors were designed to manipulate KIAA1429 expression in OS cells. Cell viability was evaluated by the MTT assay, protein expression was measured by Western blotting, and RNA expression was detected by RT-qPCR and RNA sequencing. An Edu incorporation assay, wound-healing assay, and transwell assay were performed to examine cell proliferation, migration, and invasion. A nude mouse model was used to examine the effect of KIAA1429 knockdown on tumor growth in vivo.
Findings: What Happens in Osteosarcoma Cells?
Let's take a look at the researchers' findings:
Main finding: KIAA1429 is upregulated in osteosarcoma cell lines compared to a human osteoblast cell line.
Knockdown of KIAA1429 significantly decreased OS cell viability, proliferation, migration, and invasion in vitro.
Additionally, KIAA1429 deletion remarkably blocked the growth of OS in vivo.
RNA-sequencing revealed that KIAA1429 knockdown altered the whole transcriptome, with changes in 605 differentially expressed genes.
Pathway enrichment analysis indicated that KIAA1429 may play a role in the PI3K/AKT signaling pathway.
The study suggests that KIAA1429 promotes OS growth and could be a potential therapeutic target for OS.
