lncRNA - Long Non-coding RNAs02:39

lncRNA - Long Non-coding RNAs

7.5K
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...

Regulation of Hematopoietic Stem Cells

3.4K
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...

Role of Hematopoietic Growth Factors

3.9K
Hematopoietic growth factors are molecules that regulate the differentiation rate of hematopoietic stem cells (HSCs). Erythropoietin (EPO), primarily produced by the kidneys, plays a crucial role in erythrocyte production. When oxygen levels in the blood are low, EPO is released into the bloodstream, reaching the bone marrow, where it stimulates HSCs to differentiate and mature into erythrocytes, which are vital for oxygen transport.
Thrombopoietin (TPO), mainly released by the liver,...

Hematopoiesis01:21

Hematopoiesis

8.1K
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...

Types of RNA01:20

Types of RNA

13.9K
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.

Area of Science:

  • Hematology
  • Molecular Biology
  • Epigenetics

Background:

  • Long noncoding RNAs (lncRNAs) are recognized for diverse roles in cellular development and disease.
  • Their specific functions in hematopoiesis (blood cell development) are an active area of research.

Purpose of the Study:

  • To review recent advancements in understanding lncRNAs involved in blood cell development.
  • To highlight the role of lncRNAs in epigenetic regulation of gene expression during hematopoiesis.
  • To discuss the implications of lncRNA dysregulation in malignant hematopoiesis and blood cancers.

Main Methods:

  • Literature review focusing on lncRNA research in hematopoiesis.
  • Emphasis on studies investigating epigenetic mechanisms controlled by lncRNAs.
  • Analysis of data linking lncRNA dysregulation to blood cancers like leukemia.

Main Results:

  • lncRNAs regulate blood cell fates, often through epigenetic control of gene expression.
  • Dysregulation of specific lncRNAs and their targets is observed in malignant hematopoiesis.
  • In some cases, lncRNA dysregulation alone can induce malignant hematopoiesis in mouse models.

Conclusions:

  • lncRNAs play critical roles in normal and malignant hematopoiesis.
  • lncRNAs show potential as diagnostic and prognostic markers for blood cancers.
  • lncRNAs may serve as novel therapeutic targets for treating blood cancers.
