Summary
Long noncoding RNAs (lncRNAs) are key players in blood cell development and cancers like leukemia. These molecules regulate gene expression and may serve as diagnostic markers or therapeutic targets for blood cancers.
Area of Science:
- Molecular Biology
- Genetics
- Oncology
Background:
- Long noncoding RNAs (lncRNAs) exhibit differential abundance and activity, serving as hallmarks in various diseases.
- lncRNAs play crucial roles in normal blood cell development.
- Dysregulation of lncRNAs is implicated in various cancers, particularly blood cell malignancies.
Purpose of the Study:
- To highlight the functional roles of lncRNAs in blood cell development.
- To explore the involvement of lncRNAs in malignant hematopoiesis and blood cell cancers.
- To discuss the potential of lncRNAs as diagnostic, prognostic, and therapeutic agents in hematologic malignancies.
Main Methods:
- Literature review and analysis of existing research on lncRNA function in hematopoiesis and cancer.
- Examination of mechanisms by which lncRNAs regulate gene expression, including chromatin remodeling and epigenetic silencing.
- Investigation of the association between lncRNAs, protein complexes, and oncogenic/tumor suppressor gene activity.
Main Results:
- lncRNAs are functionally significant in blood cell development.
- Multiple lncRNAs are implicated in normal and malignant hematopoiesis, including leukemia.
- lncRNAs regulate gene expression by influencing chromatin remodeling complexes and epigenetic silencing, affecting tumor suppressor and oncogenes.
Conclusions:
- lncRNAs are critical regulators in both normal blood cell formation and the development of blood cancers.
- The aberrant expression and activity of lncRNAs are strongly linked to hematologic malignancies.
- lncRNAs hold significant promise as biomarkers for diagnosis and prognosis, and as targets for novel lncRNA-mediated therapies in blood cancers.

02:39lncRNA - 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)...

01:21Hematopoiesis
The process of blood cell formation is called hematopoiesis. Hematopoiesis starts early during development, on the seventh day of embryogenesis. This phase of hematopoiesis is called the primitive wave, wherein the extraembryonic yolk sac allows the production of erythroid cells and endothelial cells from a common precursor called hemangioblast. The erythroid cells provide oxygen to support the growth of the rapidly dividing embryo. Hemangioblasts later develop into hematopoietic stem cells or...
01:01Regulation of Hematopoietic Stem Cells
All blood and immune cells are produced from the multipotent hematopoietic stem cells (HSCs) by the process of hematopoiesis. However, they all have a limited life span. In addition, many are depleted in immune surveillance or combatting an injury or infection. This makes blood one of the most regenerative tissues. Hematopoiesis helps replenish these blood and immune cells, restoring the body's normal functioning. However, overproduction of blood and immune cells can make them cancerous or...
01:20Types of RNA
Three main types of RNA are involved in protein synthesis: messenger RNA (mRNA), transfer RNA (tRNA), and ribosomal RNA (rRNA). These RNAs perform diverse functions and can be broadly classified as protein-coding or non-coding RNA. Non-coding RNAs play important roles in regulating gene expression in response to developmental and environmental changes. Non-coding RNAs in prokaryotes can be manipulated to develop more effective antibacterial drugs for human or animal use.
