Summary
MicroRNA miR-223 plays a crucial role in regulating inflammation and preventing cancer. This microRNA impacts key cellular processes, including immune responses and myeloid differentiation, offering potential therapeutic avenues.
Area of Science:
- Molecular Biology
- Immunology
- Oncology
Background:
- MicroRNA miR-223 expression is altered in various diseases, including infections, inflammatory conditions, and cancers.
- Emerging evidence suggests miR-223's involvement in modulating inflammation and preventing oncogenic transformations.
Purpose of the Study:
- To review recent studies on miR-223 function.
- To elucidate miR-223's role in inflammation, infection, and cancer development.
Main Methods:
- Literature review of studies investigating miR-223.
- Analysis of validated miR-223 targets and their impact on cellular processes.
Main Results:
- miR-223 targets key mediators of inflammation (e.g., STAT3, NF-κB) and cancer (e.g., C/EBPβ, E2F1).
- miR-223 influences hematopoietic cell differentiation, particularly granulocytes.
- miR-223 dampens inflammatory pathways like the NLRP3 inflammasome and can directly target viruses.
Conclusions:
- miR-223 is a significant modulator of inflammation, infection, and cancer.
- Its multifaceted targeting suggests a central role in maintaining cellular homeostasis and preventing disease.

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 ends...

02:30Metastasis
Metastasis is the spread of cancer cells from the original site to distant locations in the body. Cancer cells can spread via blood vessels (hematogenous) as well as lymph vessels in the body.
Epithelial-to-Mesenchymal Transition
The epithelial-to-mesenchymal transition or EMT is a developmental process commonly observed in wound healing, embryogenesis, and cancer metastasis. EMT is induced by transforming growth factor-beta (TGF-β) or receptor tyrosine kinase (RTK) ligands, which further...

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.

02:23Abnormal Proliferation
Under normal conditions, most adult cells remain in a non-proliferative state unless stimulated by internal or external factors to replace lost cells. Abnormal cell proliferation is a condition in which the cell's growth exceeds and is uncoordinated with normal cells. In such situations, cell division persists in the same excessive manner even after cessation of the stimuli, leading to persistent tumors. The tumor arises from the damaged cells that replicate to pass the damage to the daughter...
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...
