Abstract
Fibrosis is not a disease but rather an outcome of the pathological tissue repair response. Many myofibroblasts are activated which lead to the excessive accumulation of extracellular matrix components such as collagen and fibronectin with fibrosis. A variety of organs, including kidney, liver, lung, heart and skin, can undergo fibrosis under the stimulation of exogenous or endogenous pathogenic factors. The orphan nuclear receptor 4 group A1 (NR4A1) and nuclear receptor 4 group A2(NR4A2)are belong to the nuclear receptor subfamily and inhibit the occurrence and development of fibrosis. NR4A1 is an inhibitory factor of TGF-β signaling transduction. Overexpression of NR4A1 in fibroblasts can reduce TGF-β induced collagen deposition and fibrosis related gene expression. Here, we summarize the current research progress on the NR4A1/2 and fibrosis, providing reference for the treatment of fibrosis.

Abstract
The expression of annexin A1 (ANXA1) is augmented by gonadotrophin releasing hormone (GnRH) in LβT2 gonadotroph. We examined the distribution of ANXA1 in the pituitary tissues and the
effect of ovariectomy. ANXA1 was mainly stained on folliculostellate cell-like irregular shaped cells with extended process of adult female rats. Large gonadotroph, so called castration
cells, appeared two weeks after the ovariectomy. ANXA1 in castration cells exists around cells although another GnRH responsive annexin, ANXA5, was apparent also in the cytoplasm. The
pituitary expression of ANXA1 after ovariectomy was significantly higher than intact rats. These difference in tissue distribution of two annexins suggest ANXA1 and ANXA5 bear different
physiological function in the gonadotroph under GnRH regulation.
