A comparison of relative rates of protein synthesis and c-fos mRNA levels during either heat shock or sodium arsenite treatment suggests that the transient suppression of protein synthesis accompanying these treatments may be one factor responsible for the observed c-fos mRNA induction.

Both acute (24 h) and chronic (10-20 week) exposure of human fibroblast cells to low dose sodium arsenite (As (III)) significantly affects activating protein-1 (AP-1) and nuclear factor kappa B (NF-kappa B) DNA binding activity.
Short-term treatment with 0.1-5 microM As (III) up-regulates expression of c-Fos and c-Jun and the redox regulators, thioredoxin (Trx) and Redox factor-1 (Ref-1) and activates both AP-1 and NF-kappa B binding.

Significant elevations in c-fos and c-jun mRNA levels were observed within 30 min after exposure to arsenic and by enhancement of AP-1 DNA binding activity and transactivation activity.

It is shown that the concentrations of arsenite that enhance the mitogenic effect of serum also increase the mRNA levels of c-fos, HSP68, and HSP84 and induce the specific synthesis of Heat Shock Proteins (HSPs).

Cancer Res. 2000 Jul 1;60(13):3445-53.

In the current studies, we demonstrate that mice exposed to 0.01% sodium arsenite in drinking water develop hyperplasia of the bladder urothelium within 4 weeks of exposure.
Gene expression studies using RNase protection assays, reverse transcription-PCR, and cDNA microarrays indicated that arsenite alters the expression of a number of genes associated with cell growth, such as c-fos, c-jun, and EGR-1, as well as cell arrest, such as GADD153 and GADD45.

Human small airway epithelial cells (SAECs) previously immortalized with human telomerase reverse transcriptase (h-TERT) were continuously treated with sodium arsenite at a dose of 0.5 microg/mL in culture for up to 6 months.
In addition, arsenic-treated cells showed an increase in c-H-ras, c-myc, and c-fos protein expression relative to controls.
