Summary

This summary is machine-generated.

Upregulated circular RNA (circRNA) expression is linked to poorer outcomes in acute myeloid leukemia (AML) patients. These findings suggest circRNAs could be valuable biomarkers for predicting AML prognosis, especially in intermediate-risk cases.

Area Of Science

  • Oncology
  • Molecular Biology
  • Genetics

Background

  • Current methods for assessing acute myeloid leukemia (AML) patient prognosis, such as cytogenetic and molecular analysis, have limitations, particularly for intermediate-risk cases.
  • Biomarkers for accurately predicting prognosis in intermediate-risk AML patients are needed to refine treatment strategies and improve patient outcomes.
  • Circular RNAs (circRNAs) are emerging as potential regulators in various cancers, but their prognostic role in AML requires further elucidation.

Purpose Of The Study

  • To conduct a meta-analysis evaluating the association between circRNA expression and prognosis in acute myeloid leukemia (AML).
  • To identify potential circRNA biomarkers for predicting prognosis, especially in intermediate-risk AML patients.
  • To provide a scientific basis for updating clinical guidelines, such as WHO practice guidelines and European LeukemiaNet (ELN) risk classification.

Main Methods

  • A comprehensive literature search was conducted across PubMed, Cochrane Library, and Web of Science databases up to September 15, 2024.
  • Included studies were assessed for quality using the Newcastle-Ottawa Scale (NOS).
  • Hazard ratios (HR) and 95% confidence intervals (CI) for overall survival (OS) and event-free survival (EFS) were pooled using STATA 17.0 software.

Main Results

  • The meta-analysis included 13 studies with a total of 1401 AML patients.
  • Upregulated circRNA expression was significantly associated with increased hazard for overall survival (HR=1.87, 95% CI=1.51-2.32, P<0.001).
  • Subgroup analyses revealed a significant increase in hazard ratio for upregulation of circRNA expression in event-free survival (HR=1.66, 95% CI=1.19-2.32, P<0.005) and specifically for circ_0012152 (HR=2.26, 95% CI=1.27-4.00, P<0.005).

Conclusions

  • Elevated circRNA expression is significantly correlated with a poorer prognosis in patients with acute myeloid leukemia (AML).
  • CircRNAs demonstrate potential as reliable prognostic markers for AML.
  • Further research focusing on the prognostic impact of circRNAs in AML is warranted to refine risk stratification and clinical management.

MicroRNAs 01:22

3.0K

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...

Abnormal Proliferation 02:23

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...
