Objective To investigate the effects of recombinant human augmenter of liver regeneration (rhALR) on renal inflammation in acute kidney injury (AKI) induced by renal ischemia reperfusion (IR). Methods SD rats were randomly divided into sham-operated group,IR group,rhALR1 group (100 μg/kg) and rhALR2 group (200 μg/kg).Both renal pedicles of rats were identified and occluded with microvascular clamps for 60 min to induce acute kidney injury (AKI).Blood urea nitrogen and serum creatinine levels were evaluated using a Hitachi 747 automatic analyzer. For histological examination, sections were stained with HE. The activity of myeloperoxidase (MPO) was detected by spectrophotometer.Expression of TNF-α,ICAM-1,MCP-1 was determined by Western blotting. Results Blood urea nitrogen,serum creatinine levels and the injury of kidney were improved significantly in rhALR group as compared with IR group (all P< 0.05).They were improved more significantly in rhALR2 group as compared to in rhALR1 group (all P<0.05).The protein levels of TNF-α,ICAM-1,MCP-1 and the activity of MPO in kidneys from the sham-operated rats were low,and increased significantly after renal ischemia reperfusion injury (all P<0.05).After treated with rhALR,the expression of TNF-α,ICAM-1,MCP-1 and the activity of MPO were decreased significantly in kidneys as compared to those in IR group (all P<0.05),which decreased more significantly in rhALR2 group than those in rhALR1 group (all P< 0.05). Conclusions nhALR can protect kidneys from ischemia reperfusion injury in rats.The mechanism may be associated with the inhibition of renal inflammatory cells infiltration and down-regulated expressions of YNF-α,ICAM-1 and MCP-1 in the kidney.

Objective: To study the possible role and way of ALR in the immune regulation in vitro. Methods: The proliferation of spleen mononuclear cells of rat was detected with 3H-TdR method in vitro under the following different treatments:(1)the administration of the different concentration of rALR with 5 ?g/ml ConA at same time;(2)the addition of 30 ?g/ml ALR after 5 ?g/ml ConA pretreatment in 10 h and 32 h, respectively;(3)the addition of 5 ?g/ml ConA after 30 ?g/ml ALR pretreatment until 30 h. Cyclosporin A and the supernatant from cultures of yeast were used as positive and negative controls, respectively. The IL-2 levels in the supernatants from the mononuclear cells by various treatments were detected with RIA test kit. Results: rALR inhibited the proliferation and the production of IL-2 of the mononuclear cells from rat spleen stimulated by ConA dose-dependently. The mononuclear cell proliferations were still inhibited by 30 ?g/ml rALR after stimulated by ConA for 10 h or 32 h, but the pretreatment of 30 ?g/ml rALR for 30 h had no influence on the reactivity of mononuclear cell to ConA compared with control. Conclusion: rALR could inhibit in dose-dependent way the proliferation of mononuclear cells from rat spleen stimulated by ConA in vitro, but it couldn’t influence the rest mononuclear cells. This suggests that the rest mononuclear cells might not express the receptor of ALR.

Recent studies suggested that the prostate cancer may arise from prostate cancer stem cells that share some same characteristics with normal stem cells. The purpose of this study was to detect the differences of Nanog expression between PC3 prostate cancer cell line and its tumor stem cells, and the relationship was preliminarily examined between Nanog and prostate cancer and its tumor stem cells. By using magnetic active cell sorting (MACS), we isolated a population of CD44(+)/CD133(+) prostate cancer cells that display stem cell characteristics from PC3 cell line. Immunohistochemistry revealed positive expressions of CD44, CD133 and α(2)β(1)-integin in the isolated cells. CCK-8 analysis showed that isolated cells had a strong proliferative ability. The formation of the cell spheres in serum-free medium and holoclones in serum-supplied medium showed that the cells were capable of self-renewing, indicating that the isolated cells were a population of cancer stem-like cells derived from PC3 cell line. Western blotting exhibited that the isolated cells had higher experession of Nanog, an embryonic stem marker, as compared with PC3 cells. Our study showed that Nanog might be helpful in sustaining the self-renewal and the undifferentiation of prostate cancer stem cells, and may serve as a marker for prostate cancer stem cells for isolation and identification.
