EXPRESSION

UNIPROT
LITERATURE
an increase in the level of catalase transcripts is detected after 1 day of auxin treatment, then the expression of the aforementioned gene decreases, auxin stimulates catalase activity only in the distal zone of the root
at 0.5 mM N-NO3- with 3 mM carbon/l humic acid, the catalase activity is higher than control, by about 400%, whereas at 5 mM N-NO3- this increase is 80% as compared to control
-
CatP presents high levels of expression in the yeast parasitic phase
expression in gills increases 3.2 and 3fold in response to hypoxia and reoxygenation (6 and 24 h hypoxia, followed by 1 h reoxygenation) compared to normoxia, while no differences are detected in the expression and activity in hepatopancreas. Catalase activity in gills has a contrary response to expression in hypoxia and reoxygenation
expression is induced by by 2% ethanol stress
expression level of catalase transcripts both in haemocytes and hepatopancreas changes rapidly and dynamically after Vibrio alginolyticus challenging in the intermoult stage
expression of the katA gene is induced in response to O2 exposure
high concentration of methyl jasmonate (0.1 mM) provoke a reduction of catalase activity in both periods tested (measured 24 h and 48 h after each stimulus)
Hydrae exposed to thermal, starvation, metal and oxidative stress respond by upregulating its catalase mRNA transcription, RT-PCR expression analysis, overview
in Portunus trituberculatus challenged with the Hematodinium parasite, transcripts in hemocytes are significantly decreased at 3 h, and then increased significantly from 6 to 24 h with a peak at 12 h, followed by significant decrease at 96 and 192 h
progesterone (0.1 mM) induces catalase activities in T47-D cells, Org2058 (0.1 mM) induces catalase activities in T47-D cells and HBE cells after 48 h of treatment, norethisterone acetate (0.001 mM) induces catalase activities in T47-D cells, tibolone (0.001 mM) induces catalase activities in T47-D cells and HBE cells after 48 h of treatment
-
the positive effect of lower amounts of methyl jasmonate on the catalase activity is more prominent during the first 24 h. Catalase activity increases upon all salicylic acid treatments (1, 5 and 10 mM)
transcription is upregulated by low salinity, heat, and oxidative stresses
