How does pco2 impact charge variant in CHO cell cultures? 


Best insight from top research papers

Elevated pCO2 concentrations in CHO cell cultures have been found to impact charge variants. Studies have shown that at higher pCO2 levels, the lactate metabolic shift, which is important for cell culture longevity and final product titers, is absent compared to cultures at lower pCO2 values . Additionally, interactions between process parameters such as pH and pCO2 have been found to affect charge variants of monoclonal antibodies (mAbs) produced by CHO cells . Furthermore, the concentration of Zn2+, duration of culturing, and temperature have been shown to affect charge variants of mAbs, and the addition of carboxypeptidase B (CpB) can significantly improve the main peak of mAbs without affecting other critical quality attributes . These findings suggest that pCO2 and other process parameters can have a significant impact on charge variants in CHO cell cultures, highlighting the importance of understanding and controlling these parameters for optimizing mAb production.

Are there any other diseases that share phenotypes with Charge syndrome?5 answersCHARGE syndrome shares phenotypic characteristics with other disorders such as Kabuki syndrome (KS), Rubinstein-Taybi syndrome (RTS), Coffin-Siris syndrome (CSS), DiGeorge syndrome, Treacher Collins syndrome (TCS), and Mowat-Wilson syndrome (MWS). These disorders have overlapping features with CHARGE syndrome, including craniofacial abnormalities, cranial nerve defects, and developmental delays. The CHD7 gene, which is associated with CHARGE syndrome, is also involved in the regulation of these disorders. The identification of these shared phenotypes and the interplay between the genes involved provide insights into the underlying mechanisms and potential treatment approaches for these disorders.
What effect the basic charge variant is increase in CHO cell culture?3 answersThe increase in basic charge variants in CHO cell culture has been found to have several effects. Taurine supplementation in the feed medium has been shown to decrease basic charge variants, specifically the lysine variant, resulting in a decrease in basic variant contents. Additionally, the concentration of Zn2+ and temperature shift have been found to improve the quality of antibodies, with the main peak increasing and the acid peak decreasing. The formation of acidic charge variants during cell culture has been linked to oxidative stress, with higher acidic peaks corresponding to elevated supernatant peroxide concentration and intracellular reactive oxygen species levels. Furthermore, the presence of C-terminal lysine has been identified as a cause of higher basic species and lower main peak in intensified processes, which can be resolved by introducing carboxypeptidase B treatment. Finally, the level of proline amidation, which is sensitive to copper ion concentration, has been found to affect the basic charge variant profile of antibodies.
Is water pco2 affected by temperature?5 answersWater pCO2 is affected by temperature. In freshwater systems, increased water temperatures have been found to positively affect the total phytoplankton biomass. In seawater, the temperature effect tends to override the non-temperature effects in modulating surface pCO2 in tropical and subtropical oceanic waters. In sedimentary basins, pCO2 is primarily related to temperature due to water-mineral-gas interactions. Additionally, in cave environments, cave pCO2 shows significant seasonal variation, which is similar to the seasonal variation in rainfall. Therefore, based on the findings from these studies, it can be concluded that water pCO2 is indeed affected by temperature.
What is the relationship between pCO2 and the water column carbon cycle?5 answersElevated pCO2 levels in the water column have been found to have significant effects on the carbon cycle. Studies have shown that increased pCO2 enhances the rate and magnitude of organic carbon removal by bacterioplankton communities, leading to increased respiration and decreased growth efficiency. This ultimately decreases the amount of dissolved organic carbon (DOC) available for vertical export and increases the production of CO2 in the surface ocean. Additionally, low water levels and reduced rainfall have been associated with increased pCO2 and higher concentrations of chlorophyll-a and organic carbon in lakes, resulting in these lakes becoming sources of CO2 to the atmosphere. Furthermore, turbulence caused by waterfalls has been found to promote degassing and decrease pCO2 levels downstream, suggesting that waterfall-turbulence plays a role in unaccounted degassing and carbon processing in freshwater environments. These findings highlight the complex relationship between pCO2 and the water column carbon cycle, with elevated pCO2 levels impacting carbon removal, export, and emissions in both marine and freshwater environments.
What is the relationship between pCO2 and the water column carbon cycle in Ocean?4 answersIncreasing levels of pCO2 in the surface ocean may lead to enhanced accumulation of dissolved organic carbon (DOC) and transparent exopolymer particles (TEPs) in the surface ocean, affecting the functioning of the marine carbon cycle. Marine aggregates, such as diatom aggregates, play a critical role in the biological pump and can enhance bacterial concentration and activity, leaving behind considerable "carbon processing footprints" in the water column. Changes in the deep ocean, below 2000m, indicate the manifestation of anthropogenic and climate change signals, with an increase in deep water pCO2 and changes in inorganic carbon content. Elevated pCO2 and increased NH4+ to nitrate (NO3) ratio can depress calcification, alter coccolith morphology, and increase primary production in coccolithophores, potentially disrupting the organic carbon pump in the future acidified ocean. The δ13C of foraminifera-bound organic matter (FBOM) is investigated as a potential proxy for past surface water pCO2, showing an anticorrelation with climatological [CO2(aq)].
