Summary
MicroRNA-155 (miR-155) is an oncomir crucial in hematopoietic malignancies. Down-regulating miR-155 shows promise as a targeted therapy for these cancers.
Area of Science:
- Molecular biology
- Genetics
- Oncology
Context:
- MicroRNAs (miRNAs) are small non-coding RNAs regulating gene expression post-transcriptionally.
- miR-155 is highly expressed in hematopoietic cells and implicated in various cellular processes.
- Emerging evidence links miR-155 to the pathogenesis of hematological malignancies.
Purpose:
- To review the current understanding of miR-155's role in hematopoietic malignancies.
- To explore miR-155 as a potential diagnostic and prognostic biomarker.
- To highlight miR-155 as a therapeutic target for hematological cancers.
Summary:
- miR-155 acts as an oncomir, promoting proliferation, inhibiting differentiation, and preventing apoptosis in hematopoietic cells.
- Its dysregulation is observed in malignant lymphoma, acute myeloid leukemia, and myelodysplastic syndromes.
- miR-155 influences key cell signaling pathways involved in cancer development.
Impact:
- miR-155 serves as a potential biomarker for diagnosing and predicting outcomes in hematological malignancies.
- Targeting miR-155 with antisense oligonucleotides offers a novel therapeutic strategy.
- This approach could complement conventional cytotoxic therapies for improved cancer treatment.

MicroRNAs
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...

lncRNA - Long Non-coding RNAs
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 (lncRNA)...
