Carbonic Anhydrase 2 is Required for Maintaining Metabolic Homeostasis of Human Articular Chondrocytes

Project description:Objective: To examine the role of carbonic anhydrase II (CA2 gene), the most efficient isoform in the CA family of zinc-containing metalloenzymes, in chondrocyte metabolism. Methods: CA2 expression was measured in human and mouse osteoarthritic cartilage. RNA-seq was performed in C28/I2 cells in which CA2 was silenced. Normal human chondrocytes were cultured under normoxia (21% oxygen) or hypoxia (2% oxygen) following CA2 knockdown. Cell metabolism was studied by measuring extracellular lactate production, glucose consumption, intracellular ADP/ATP, intracellular pH, and ROS production. Glycolysis was measured using Seahorse XF96 analyzer. The effect of CA2 knockdown on anabolic and catabolic markers was measured following treatment with IL-1. Effects of CA2 was examined on cell proliferation, cell-cycle distribution, colony-formation, and migration. Results: CA2 was highly elevated in human and murine osteoarthritic cartilage. RNA-seq analysis revealed that processes related to glycolysis, apoptosis and TNF signaling were perturbed in cells lacking CA2. CA2 expression was 10-fold higher under hypoxia and its knockdown caused decreased extracellular lactate production, increased ADP/ATP ratio, impaired glycolysis, decreased glycolytic capacity and lowered the expression of glycolysis rate-limiting enzymes, but did not affect intracellular pH and ROS production. CA2 deficiency disturbed chondrocyte anabolic and catabolic equilibrium. CA2 knockdown suppressed chondrocyte migration and proliferation and induced cell-cycle arrest. Conclusion: This study unravels a novel role of CA2 in chondrocyte metabolism and inflammation. These findings indicate that CA2 is required for the maintenance of chondrocyte metabolic homeostasis. Future work is needed to further illuminate the mechanistic and functional role of CA2 in osteoarthritis development.

Global transcriptomic changes following elevated carbon dioxide (5%) in the wild-type (WT) and mutant (M2; RNAi-knockdown line of carbonic anhydrase (CA2)) Nannochloropsis oceanica IMET1: Illumina sequencing

Project description:In Nannochloropsis oceanica IMET1, transcript knockdown of a cytosolic carbonic anhydrase (CA2; g2018) specifically inhibited by HC resulted in ~45%, ~30% and ~40% elevation of photosynthetic oxygen evolution rate, growth rate and biomass accumulation rate under high CO2 (5% ), respectively. This CA2-knockdown mutant is demonated as M2. To probe mechanistic links underlying the mutant (M2; RNAi-knockdown line of carbonic anhydrase (CA2)) phenotypes, temporal transcriptomic profiles are compared between RNAi-knockdown line of carbonic anhydrase (CA2) and WT, at 12 h and 24h under high CO2 (5%).

Genes regulated by TGF-beta in bovine articular chondrocytes

Project description:Bovine articular chondrocytes were grown in micromass culture and were either untreated or treated with 5 ng TGF-b1/ml for 8 hours to identify genes regulated by TGF-b. Six total samples were analyzed. Three biological replicates of untreated bovine articular chondrocytes grown in micromass culture and three biological replicates of bovine articular chondrocytes grown in micromass culture and treated with 5ng TGF-b1/ ml for 8 hours.

Comparison between articular chondrocytes and mesenchymal stromal cells for the production of articular chondrocyte implants

Project description:Focal lesions of articular cartilage give rise to pain and reduced joint function and may, if left untreated, lead to osteoarthritis. Implantation of in vitro generated, scaffold-free autologous cartilage discs may represent the best treatment option. Here we compare articular chondrocytes (ACs) and bone marrow-derived mesenchymal stromal cells (MSCs) for their ability to make scaffold-free cartilage discs.
