Long non-coding RNAs and MYC association in hematological malignancies

Area of Science:

• Molecular Biology
• Hematology
• Genetics

Background:

• Long non-coding RNAs (lncRNAs) are key regulators of gene expression with critical roles in cell biology.
• lncRNAs play a significant role in hematopoiesis, influencing stem cell renewal and progenitor differentiation.
• The transcription factor MYC is a master regulator involved in both normal hematopoiesis and malignancies.

Purpose of the Study:

• To review the intricate crosstalk between lncRNAs and MYC in the context of hematopoiesis.
• To elucidate the pathogenetic mechanisms by which lncRNA-MYC interactions contribute to hematologic malignancies.
• To highlight recent findings on the role of lncRNAs in myeloid and lymphoid cancers.

Main Methods:

• Literature review of recent findings on lncRNA and MYC interactions.
• Analysis of the role of lncRNAs in regulating hematopoietic stem cells and progenitor differentiation.
• Examination of the impact of lncRNA-MYC axis on cancer hallmarks like apoptosis, proliferation, and metabolism.

Main Results:

• lncRNAs exhibit lineage-restricted expression patterns during hematopoiesis, distinct from coding mRNAs.
• MYC regulates lncRNA expression, and conversely, lncRNAs modulate MYC activity.
• The aberrant interaction between MYC and lncRNAs is a common feature in myeloid and lymphoid malignancies, promoting cancer progression.

Conclusions:

• The crosstalk between lncRNAs and MYC is a critical factor in the pathogenesis of acute and chronic hematologic malignancies.
• Dysregulation of this axis contributes to key cancer hallmarks, including enhanced proliferation, metabolic alterations, and treatment resistance.
• Targeting the lncRNA-MYC interaction may offer novel therapeutic strategies for hematologic cancers.
