Summary
Metastasis-associated lung adenocarcinoma transcript-1 (MALAT1), a long non-coding RNA, plays a key role in osteosarcoma (OS) development. Targeting MALAT1 may offer new diagnostic and therapeutic strategies for this bone cancer.
Area of Science:
- Oncology
- Molecular Biology
- Genetics
Background:
- Osteosarcoma (OS) is a prevalent bone cancer in children and young adults, characterized by osteogenic differentiation and metastasis.
- The precise molecular mechanisms driving OS development and progression remain incompletely understood.
- Long non-coding RNAs (lncRNAs) are increasingly recognized for their regulatory roles in cancer, including OS proliferation and drug resistance.
Purpose of the Study:
- To review the current understanding of the role of the lncRNA MALAT1 in the pathophysiology of osteosarcoma.
- To highlight MALAT1's potential as a diagnostic and therapeutic target for OS.
Main Methods:
- Literature review focusing on studies investigating MALAT1 expression and function in osteosarcoma.
- Analysis of MALAT1's involvement in key signaling pathways and microRNA interactions relevant to OS.
Main Results:
- Aberrant expression of MALAT1 is observed in various human cancers, including osteosarcoma.
- Elevated MALAT1 levels are associated with increased OS cell growth and tumorigenicity.
- MALAT1 influences OS progression by regulating specific signaling pathways and microRNAs.
Conclusions:
- MALAT1 is implicated in the pathogenesis of osteosarcoma.
- The aberrant expression and regulatory functions of MALAT1 suggest its potential as a biomarker for OS diagnosis.
- Targeting MALAT1 presents a promising avenue for novel therapeutic interventions in osteosarcoma treatment.

8.9K
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...

01:41Non-Canonical Wnt Signaling Pathways
7.4K
Wnt is a zygotic effect gene that is expressed during very early embryonic development. It regulates various processes in animals starting from early development through the adult stage, such as organogenesis in the embryo and maintenance of neuronal and blood stem cells. Wnt proteins can induce a wide variety of intracellular pathways depending upon the specific abilities of different Wnt ligands to form a complex with shared and cognate receptors in the presence of different co-receptors. The...

3.9K
The mammalian target of rapamycin or mTOR protein was discovered in 1994 due to its direct interaction with rapamycin. The protein gets its name from a yeast homolog called TOR. The mTOR protein complex in mammalian cells plays a major role in balancing anabolic processes such as the synthesis of proteins, lipids, and nucleotides and catabolic processes, such as autophagy in response to environmental cues, such as availability of nutrients and growth factors.

02:54Canonical Wnt Signaling Pathway
8.9K
The gene encoding the main signaling molecules of the Wnt signaling pathways (the Wnt proteins) was discovered almost four decades ago by Nüsslein-Volhard and Wieschaus. They identified and originally named the gene "wingless" (wg) after a phenotype discovered during their landmark genetic screen in Drosophila for body pattern defects. At around the same time, another researcher named Harold Varmus found that a murine tumor virus activates the mammalian wg homolog, Int-1, which...

01:22PI3K/mTOR/AKT Signaling Pathway
3.9K
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...

Signaling cascades usually lack linearity. Multiple pathways interact and regulate one another, allowing cells to integrate and respond to diverse environmental stimuli.
Convergence and divergence, and cross-talk between signaling pathways
Two distinct signaling pathways can converge on a single functional unit, which may either be a single protein or a complex of proteins. The response is either functionally distinct or synergistic between the two pathways but different from the response...
