Summary
MicroRNAs (miRNAs) are crucial in regulating cell functions and are implicated in T cell acute lymphoblastic leukemia (T-ALL). Research is vital to identify miRNAs as potential diagnostic and predictive factors for T-ALL.
Area of Science:
- Oncology
- Genetics
- Molecular Biology
Background:
- T cell acute lymphoblastic leukemia (T-ALL) is a heterogeneous cancer with poor prognosis and limited prognostic factors.
- Genetic and epigenetic abnormalities drive T-ALL development.
- MicroRNAs (miRNAs) regulate cellular functions, but their role in T-ALL prognosis is not yet established.
Purpose of the Study:
- To review and characterize microRNAs in pediatric T-ALL patients.
- To explore the potential of miRNAs as predictive factors in T-ALL.
Main Methods:
- Genomic and transcriptomic analysis using microarray and next-generation sequencing (NGS).
- Literature review focusing on miRNA dysregulation in T-ALL.
Main Results:
- T-ALL exhibits significant genomic and transcriptomic complexity.
- Altered gene expression in T-ALL may result from widespread miRNA dysregulation.
- No specific miRNA has been identified as a significant prognostic or diagnostic factor to date.
Conclusions:
- MicroRNA dysregulation is a key feature of T-ALL.
- Further research into pediatric T-ALL microRNAs is essential for developing novel predictive biomarkers.
- Identifying specific miRNAs could improve T-ALL patient outcomes.

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...

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...
