Summary
Long non-coding RNA HOXA-AS3 promotes osteosarcoma (OS) progression by increasing proliferation, migration, and invasion. Targeting the HOXA-AS3/miR-1286/TEAD1 axis offers a potential therapeutic strategy for osteosarcoma.
Area of Science:
- Molecular Biology
- Oncology
- Genetics
Background:
- Long non-coding RNAs (lncRNAs) are increasingly recognized for their roles in cancer.
- The specific function of HOXA cluster antisense RNA 3 (HOXA-AS3) in osteosarcoma (OS) is not well understood.
Purpose of the Study:
- To investigate the role and underlying mechanism of HOXA-AS3 in osteosarcoma progression.
- To explore HOXA-AS3 as a potential therapeutic target for OS.
Main Methods:
- Analysis of HOXA-AS3 expression in OS tissues and cell lines.
- In vitro and in vivo experiments involving HOXA-AS3 silencing in OS cells.
- Investigation of the competing endogenous RNA (ceRNA) network involving HOXA-AS3, miR-1286, and TEAD1.
Main Results:
- HOXA-AS3 was upregulated in OS tissues and associated with poor clinical outcomes.
- Silencing HOXA-AS3 inhibited OS cell proliferation, migration, invasion, and tumorigenesis.
- HOXA-AS3 promotes proliferation, migration, and epithelial-to-mesenchymal transition (EMT) in OS by upregulating TEAD1 via sponging miR-1286.
Conclusions:
- The HOXA-AS3/miR-1286/TEAD1 axis plays a crucial oncogenic role in osteosarcoma progression.
- HOXA-AS3 represents a promising therapeutic target for osteosarcoma treatment.

8.6K
In humans, more than 80% of the genome gets transcribed. However, only around 2% of the genome codes for proteins. The remaining part produces non-coding RNAs which includes ribosomal RNAs, transfer RNAs, telomerase RNAs, and regulatory RNAs, among other types. A large number of regulatory non-coding RNAs have been classified into two groups depending upon their length – small non-coding RNAs, such as microRNA, which are less than 200 nucleotides in length, and long non-coding RNA...

6.4K
Tumor progression is a phenomenon where the pre-formed tumor acquires successive mutations to become clinically more aggressive and malignant. In the 1950s, Foulds first described the stepwise progression of cancer cells through successive stages.
Colon cancer is one of the best-documented examples of tumor progression. Early mutation in the APC gene in colon cells causes a small growth on the colon wall called a polyp. With time, this polyp grows into a benign, pre-cancerous tumor. Further...

01:22MicroRNAs
3.0K
MicroRNA (miRNA) are short, regulatory RNA transcribed from introns (non-coding regions of a gene) or intergenic regions (stretches of DNA present between genes). Several processing steps are required to form biologically active, mature miRNA. The initial transcript, called primary miRNA (pri-mRNA), base-pairs with itself, forming a stem-loop structure. Within the nucleus, an endonuclease enzyme, called Drosha, shortens the stem-loop structure into hairpin-shaped pre-miRNA. After the pre-miRNA...

01:12Loss of Tumor Suppressor Gene Functions
4.9K
Tumor suppressor genes are normal genes that can slow down cell division, repair DNA mistakes, or program the cells for apoptosis in case of irreparable damage. Hence, they play an essential role in preventing the proliferation of damaged cells.
When the tumor suppressor genes develop mutations or are lost, cells start growing out of control, leading to cancer. However, a single functional copy of the tumor suppressor gene is enough for the cells to maintain their normal functions and cell...

3.6K
The mammalian target of rapamycin (mTOR) is a serine/threonine kinase that regulates growth, proliferation, and cell survival in response to hormones, growth factors, or nutrient availability. This kinase exists in two structurally and functionally distinct forms: mTOR complex 1 (mTORC1) and mTOR complex 2 (mTORC2). The first form (mTORC1) is composed of a rapamycin-sensitive Raptor and proline-rich Akt substrate, PRAS40. In contrast, mTORC2 consists of a...

01:16TGF - β Signaling Pathway
7.4K
The TGF-β signaling pathway regulates cell growth, differentiation, adhesion, motility, and development. TGF-β ligands that induce TGF-β signaling are synthesized in their latent form. Several proteases or cell surface receptors such as integrins act upon the latent form, releasing the active ligand. There are three types of mammalian TGF-βs: (TGF-β1, TGF-β2, and TGF-β3) that bind as homodimers or heterodimers to TGF-β receptors. The TGF-β receptors...
