He also points out that there are various non-photosynthetic biochemical roles of CA in cyanobacteria and microalgae, as it can catalyse many other carboxylase reactions.

Representative images of theimmunohistochemical visualization of (A) hypoxia induciblefactor-1α, (B) carbonic anhydrase-IX, (C) glucose transporter-1 and(D) vascular endothelial growth factor in cervical squamous cellcarcinoma. Fixed cells were stained with specific antibodies andhorseradish-peroxidase secondary antibodies, and thencounterstained with hematoxylin (magnification, ×200).

Roughton and Booth (1933) first measured the activity of carbonic anhydrase using a manometric method, i.e.

Correlation of PFS with HIF-1α, CA-IX,GLUT-1 and VEGF expression levels. Expression of HIF-1α, CA-IX,GLUT-1 and VEGF was immunohistochemically analyzed in 54 patientswith cervical cancer. PFS time over 135 months was analyzed usingthe Kaplan-Meier method and a log-rank test. HIF-1α,hypoxia-inducible factor-1α; CA-IX, carbonic anhydrase-IX; GLUT-1,glucose transporter-1; VEGF, vascular endothelial growth factor;PFS, progression-free survival.

Correlation of progression-freesurvival with HIF-1α, CA-IX, GLUT-1 and VEGF expression levels incervical cancer patients treated with radiotherapy orchemo-radiotherapy following radical hysterectomy. Expression ofHIF-1α, CA-IX, GLUT-1 and VEGF was immunohistochemically analyzedin 35 patients with cervical cancer. Progression-free survival timeover 110 months was analyzed using the Kaplan-Meier method and alog-rank test. HIF-1α, hypoxia-inducible factor-1α; CA-IX, carbonicanhydrase-IX; GLUT-1, glucose transporter-1 glucose transporter-1;VEGF, vascular endothelial growth factor; PFS, progression-freesurvival.

Roles of carbonic anhydrase in photosynthesis of ..

It was the study of CO2 transport in the blood and across the surface of the human lungs which led to the discovery of carbonic anhydrase.

Hewettemmett and Tashian (1996) have recently analysed the amino acid sequences of many different carbonic anhydrases from both animals and plants, and from this have derived an evolutionary tree showing that the "eukaryotic" CA of freshwater algae is much closer to that of mammals than it is to the "prokaryotic" CA of the higher plants, which seems to be closer to the CA extracted from bacteria and cyanobacteria.

It was only when investigators started growing cultures in equilbrium with atmospheric CO2, rather than the 5% CO2 atmosphere often used to encourage rapid growth, that they found evidence of carbonic anhydrase (using a variety of measurement techniques discussed in ).
