Genome-wide Association Studies-GWAS01:11

Genome-wide Association Studies-GWAS

14.0K
Genome-wide association studies or GWAS are used to identify whether common SNPs are associated with certain diseases. Suppose specific SNPs are more frequently observed in individuals with a particular disease than those without the disease. In that case, those SNPs are said to be associated with the disease. Chi-square analysis is performed to check the probability of the allele likely to be associated with the disease.
GWAS does not require the identification of the target gene involved in...

Osteoclasts in Bone Remodeling01:31

Osteoclasts in Bone Remodeling

3.1K
Osteoclasts are cells responsible for bone resorption and remodeling. They originate from hematopoietic progenitor cells present in the bone marrow. Numerous progenitor cells fuse to form multinucleated cells, each with 10-20 nuclei. A single osteoclast has a diameter of 150 to 200 µM. These cells have ruffled borders that break down the underlying bone tissue and release minerals such as calcium into the blood in bone resorption. Osteoclasts cling to bones with their ruffled edges during...

The JAK-STAT Signaling Pathway01:20

The JAK-STAT Signaling Pathway

9.2K
Several cytokine receptors have tightly bound Janus kinase or JAK proteins attached at their cytosolic tail. Small signaling molecules such as cytokines, growth hormones, or prolactins bind to the cytokine receptors and initiate their dimerization. The dimerization brings the cytosolic JAKs together that trans-phosphorylate and activates each other. The activated JAKs now phosphorylate cytosolic tails of the cytokine receptors, which serve as binding sites for adaptor proteins such as  SH2...

NF-κB-dependent Signaling Pathway

7.8K
The transcription factor NF-κB was discovered in 1986 in the lab of Nobel laureate Professor David Baltimore, for its interaction with the immunoglobulin light chain enhancer in B-cells. After more than three decades of study, it is now evident that NF-κB regulates the expression of over 100 genes. Most of these genes play an essential role in the innate and adaptive immune responses as well as the inflammatory responses of animals.

Bone Disorders

3.8K
Aging and its effect on bone remodeling is the most common cause of bone disorders. In young and healthy people, bone deposition and resorption happen at an equal rate to maintain optimal bone health.
Bone deposition is also affected by the levels of sex hormones like estrogen and testosterone that promote osteoblast activity and bone matrix synthesis. When the level of these hormones decreases due to aging, it causes a reduction in bone deposition. As a result, bone resorption by osteoclasts...

Area of Science:

  • Biochemistry
  • Molecular Biology
  • Rheumatology

Background:

  • Osteoarthritis (OA) is a prevalent degenerative joint disease characterized by cartilage erosion, subchondral bone changes, and inflammation.
  • Current therapeutic strategies for OA are limited due to incomplete understanding of its complex molecular mechanisms.
  • While gene transcription is heavily studied, posttranscriptional regulation by RNA binding proteins (RBPs) also significantly impacts OA-related inflammation and metabolism.

Purpose of the Study:

  • To review the current knowledge on the function of dysregulated RNA binding proteins (RBPs) in osteoarthritis (OA).
  • To highlight the importance of identifying RBPs involved in OA pathophysiology.
  • To explore RBPs as potential therapeutic targets for osteoarthritis treatment.

Main Methods:

  • Literature review of recent studies on RNA binding proteins (RBPs) and osteoarthritis (OA).
  • Analysis of the role of RBPs in posttranscriptional gene regulation relevant to OA.
  • Synthesis of information on the impact of RBPs on chondrocyte function and inflammation in OA.

Main Results:

  • RBPs are critical regulators of RNA stability, localization, and translation, influencing protein expression.
  • Dysregulation of specific RBPs is implicated in the inflammatory and metabolic changes observed in OA.
  • The precise role of most RBPs in OA pathogenesis remains to be fully elucidated.

Conclusions:

  • Identifying and understanding the function of RBPs in OA is essential for advancing OA research.
  • RBPs represent promising targets for the development of novel therapeutic strategies for osteoarthritis.
  • Further investigation into RBP-mediated posttranscriptional regulation offers new insights into OA pathophysiology.
