Summary
MicroRNAs (miRNAs) are key communicators in the tumor microenvironment, influencing cancer progression. Understanding these molecular interactions is crucial for addressing cancer invasion and metastasis.
Area of Science:
- Oncology
- Molecular Biology
- Genetics
Background:
- The tumor microenvironment significantly impacts cancer development and progression.
- Mechanisms of communication between the tumor microenvironment and cancer cells, particularly microRNAs (miRNAs), are under active investigation.
- miRNAs are small noncoding RNAs regulating gene expression post-transcriptionally and are implicated in various cancers.
Purpose of the Study:
- To review the influence of microRNAs (miRNAs) on the tumor microenvironment.
- To elucidate the role of miRNAs in cancer progression, invasion, and metastasis.
Main Methods:
- Literature review focusing on the role of miRNAs in the tumor microenvironment.
- Analysis of existing research on miRNA expression and function in cancer.
- Synthesis of findings related to miRNA-mediated crosstalk and its impact on cancer cell behavior.
Main Results:

01:22MicroRNAs
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...

02:17The Tumor Microenvironment
Every normal cell or tissue is embedded in a complex local environment called stroma, consisting of different cell types, a basal membrane, and blood vessels. As normal cells mutate and develop into cancer cells, their local environment also changes to allow cancer progression. The tumor microenvironment (TME) consists of a complex cellular matrix of stromal cells and the developing tumor. The cross-talk between cancer cells and surrounding stromal cells is critical to disrupt normal tissue...

03:03mTOR Signaling and Cancer Progression
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.
