Hsp70 was not induced by treatment with sodium arsenite, azetidine-2-carboxylic acid, or zinc sulfate at the level of heat shock factor (HSF) 1 activation in cells incubated at low temperature, although these treatments induced hsp70 in cells incubated at 37 degrees C.

Mouse 70-kDa heat shock proteins Hsp70-1 and Hsp70-3 (Hsp70-1/3) are stress-inducible protein chaperones thought to protect embryonic cells and tissues from the effects of a wide range of environmental exposures.
Limiting expression of Hsp70-1/3 with 5 microM A070-1/3 also heightened embryo sensitivity to arsenic, resulting in less than 5% in vitro development to blastocyst in the presence of the subtoxic dose of 0.4 microM sodium arsenite.

Curcumin, a major component of turmeric, a seasoning commonly used in Indian food, and a known antioxidant, anti-inflammatory and anti-carcinogenic agent, is a potent stimulator of the stress-induced expression of Hsp27, alphaB crystallin and Hsp70.

In these cell lines, stresses induced by exposure to inorganic [Sodium Arsenite (NaAsO2) and Cadmium Chloride (CdCl2)], and organic [Benzo (a) Pyrene (BaP), PentaChloroPhenol (PCP), TetraChloroHydroQuinone (TCHQ), 1-Chloro-2,4-DiNitro-Benzene (CDNB)] compounds, specifically induced hGH release in the culture medium.
We previously described transgenic mice (Hsp70/hGH) secreting high levels of human Growth Hormone (hGH) following exposure to toxic compounds in vivo and in vitro in primary cultures derived from different organs.

Sublethal heat shock and exposure to several toxic compounds increase the level of Bm1 RNA, the silkworm SINE transcript, while also transiently increasing expression of a well-characterized stress-induced transcript, Hsp70 messenger RNA (mRNA).

Inducible HSP70s encoded by two almost identical hsp70 genes, known as hsp70.1 and hsp70.3 are located in a tandem array on mouse chromosome 17.
L-azetidine-2-carboxylic acid, sodium arsenite, CdCl2 and ZnCI2 caused induction of both isoforms of the hsp70 genes, even though their expression levels were variable.

The aim of this study was to clarify the effects of the induction of HSP70s on cisplatin (CDDP) (6 mg/kg i.v.)-induced ARF in rats.
Uranyl acetate (UA) or sodium arsenite (SA) were administered i.v. 14 days or 1 day respectively before CDDP injection to induce HSPs.

The unactivated steroid receptors are chaperoned into a conformation that is optimal for binding hormone by a number of heat shock proteins, including Hsp90, Hsp70, Hsp40, and the immunophilin, FKBP52 (Hsp56).

Hsp70 from trout comigrates with the major hsp from Drosophila melanogaster on sodium dodecyl sulfate - polyacrylamide gels, suggesting that this protein may be highly conserved in evolution.

Exposure of hepatocytes to either heat shock (HS;+15 degrees C) or sodium arsenite (50 microM) did not affect cell viability, but resulted in significantly higher hsp70 levels over a 24 h recovery period.
