Differentially expressed gene profiles in CA 9-transfected C33-A, human cervix carcinoma cell line

ABSTRACT: Carbonic anhydrase IX (CA 9) is a transmembrane isoform of carbonic anhydrase (CA) that contributes to an acidification of tumor microenvironment. The expression of CA 9 in cervical tumors was shown to be strongly involved in high incidence of metastasis and poor prognosis. To search for the key regulators of metastasis related to ectopic expression of CA 9, we investigated differentially expressed gene profiles in CA 9- transfected cervix carcinoma cell line C33-A (CF) compared with mock-transfected (CP) cell line, using Affymetrix Human Genome U133 Plus 2.0 Array.

CF and CP stable cell-lines trasfected respectively with full-length human CA 9 cDNA cloned into the vector pcDNA3.0 and empty vector control were used for RNA extraction and hybridization on affymetrix microarrays.

Transcriptomic signature of treatment with recombinant laminin 511-E8 and acetazolamide in human H69 cholangiocytes

Project description:IgG4-related cholangitis (IRC) is the hepatobiliary manifestation of IgG4-related disease (IgG4-RD), a systemic, B-cell driven, fibroinflammatory disorder. To date, numerous autoantigens have been described including laminin 511-E8 and carbonic anhydrase (CA) enzymes (PMID 30089633, 15647194). Laminin 511-E8 is an extracellular matrix protein that has been shown to upregulate secretory components and aid in the cholangiocyte differentiation of induced pluripotent stem cells (PMID 27103433). Carbonic anhydrase enzymes catalyse the reversible hydration of carbon dioxide, thereby producing bicarbonate and a single proton. In humans there are 14 different CA isoforms with a confined subcellular distribution. All isoforms can be targeted by the pan-CA inhibitor acetazolamide, which is a registered drug for multiple indications. We aimed to investigate the role of IgG4-RD autoantigens laminin 511-E8 and CA enzymes in human cholangiocytes. Transcriptional profiling may provide insights into the underlying molecular mechanisms of these proteins on the cholangiocellular level. Thus, by RNA sequencing the transcriptomic signature of recombinant laminin 511-E8 and acetazolamide treatment was assessed in human H69 cholangiocytes.

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%).

Global transcriptional response to carbonic anhydrase IX deficiency in the mouse stomach

Project description:Background Carbonic anhydrases (CAs) are a family of enzymes that regulate pH homeostasis in various tissues. CA IX is an exceptional member of this family because in addition to the basic CA function, it has been implicated in several other physiological and pathological processes. Functions suggested for CA IX include roles in cell adhesion and malignant cell invasion. In addition, CA IX likely regulates cell proliferation and differentiation, which was demonstrated in Car9‾/‾ mice. These mice had gastric pit cell hyperplasia and depletion of chief cells; however, the specific molecular mechanisms behind the observed phenotypes remain unknown. Therefore, we wanted to study the effect of CA IX deficiency on whole-genome gene expression in gastric mucosa. This was done using Illumina Sentrix Mouse-6 Expression BeadChip arrays. The expression of several genes with notable fold-change values was confirmed by QRT-PCR. Results CA IX deficiency caused the induction of 86 genes and repression of 46 genes in the gastric mucosa. There was 92.9% concordance between the results obtained by microarray analysis and QRT-PCR. The differentially expressed genes included those involved in developmental processes and cell differentiation. In addition, CA IX deficiency altered the expression of genes responsible for immune responses and downregulated the expression of several digestive enzymes. Conclusions Microarray analysis identified several potential genes whose altered expression could explain the disturbed cell lineage phenotype in the Car9‾/‾ gastric mucosa. The results also indicated a novel role for CA IX in the regulation of immunologic processes and digestion. These findings reinforce the concept that the main role of CA IX is not the regulation of pH in the stomach mucosa. Instead, it is needed for proper function of several physiological processes.

Expression data from C33-A cell line

Project description:C33-A is a Homo sapiens cervix carcinoma cell line. In this experiment we determine the level of gene expression under exponentially growing conditions. The final goal of the experiment is to correlate other epigenetic characteristics from other experiments with gene expression levels. C33-A cells from three independent exponentially growing cultures were recovered and processed for RNA extraction and hybridization on Affymetrix microarrays

Genome-wide synthetic lethal screen unveils novel CAIX – NFS1/xCT axis as a targetable vulnerability in hypoxic solid tumors.

Project description:Hypoxia is an important clinicopathological feature of solid tumours that limits response to therapy. Carbonic Anhydrase IX (CAIX) is a hypoxia-induced, pH regulator that has emerged as a viable therapeutic target. Targeting CAIX has demonstrated promise in difficult to treat preclinical models of breast pancreatic, melanoma and brain cancers when combined with chemotherapy and immunotherapy, however resistance ultimately develops and this mechanism is unclear. Here we used an unbiased genome-wide synthetic lethal CRISPR knock-out screen in basal breast cancer cells to identify co-vulnerabilities and mechanisms of compensation for CA9 loss. We identified a redox homeostasis network containing thioredoxin and the iron-sulfur cluster enzyme, cysteine desulfurase, NFS1, indicative of the critical importance of CAIX in this role.
