In this study, we have examined the role of HSP70 in gastric ulcer healing. Gastric ulcers were produced by focal and serosal application of acetic acid. Expression of HSP70 was induced in both the gastric ulcer margin and granulation tissue. Compared with wild-type mice, gastric ulcer healing was accelerated in transgenic mice expressing HSP70, and both cell proliferation at the gastric ulcer margin and angiogenesis in granulation tissue were enhanced. Oral administration of geranylgeranylacetone, an inducer of HSPs, to wild-type mice, either prior to or after ulcer formation, not only induced expression of HSP70 in the stomach but also accelerated gastric ulcer healing. On the other hand, oral administration of purified recombinant HSP70 prior to the ulcer formation, but not after formation, stimulated gastric ulcer healing. This study provides the first evidence that HSP70 accelerates gastric ulcer healing.

在这项研究中，我们研究了HSP70在胃溃疡愈合中的作用。胃溃疡是通过乙酸的局灶性和浆膜应用产生的。 Hsp70的表达均在胃溃疡和肉芽组织中诱导。与野生型小鼠相比，在表达HSP70的转基因小鼠中加速了胃溃疡愈合，并且在胃溃疡边缘处的细胞增殖和肉芽组织中的血管生成。在溃疡形成之前或之后，口服HSP的诱导剂的香烷基果仁酮（HSP的诱导剂）不仅诱导HSP70在胃中的表达，而且还会加速胃溃疡愈合。另一方面，在溃疡形成之前口服纯化的重组HSP70，但在形成后不刺激胃溃疡愈合。这项研究提供了HSP70加速胃溃疡愈合的第一个证据。
