Figure Lengend Snippet: miR-21 and PPAR-α expressions in HK-2 and renal cancer cell lines before confluence (BC) and two days after confluence (C + 2). ( A ) Using RT-qPCR, miR-21 expression was determined in the 786-O, ACHN, RCC10, and RCC4 renal cancer cells as compared to normal HK-2 renal epithelial cells. RNU48 was used as an internal control. The values are means ± SEM and represent at least three separate experiments (* p < 0.05, ** p < 0.01, and *** p < 0.001). ( B ) Western blotting was performed on whole cell extracts. Antibodies against PPAR-α and β-actin were used.

Figure Lengend Snippet: AQP1 and NKCC1 distribution in the CNS leptomeningeal vasculature. Scheme representing the mouse brain parenchyma, the skull and the meninges, which encompass the brain and also the spinal cord. The meninges are divided into the dura mater and the leptomeninges, corresponding to the arachnoid and pia mater. The brain and spinal parenchyma are separated from the meninges by the basal lamina and the glia limitans. The arachnoid mater forms the outer barrier of the CNS and underneath it lies the subarachnoid space (SAS), which is filled with CSF. Immune cells, namely macrophages and leucocytes, are sparsely present within the SAS, surveilling the healthy CNS. Additionally to its function as route for CSF and immune cells circulation, the SAS encloses the arterial blood supply to the CNS. Prior to entering the CNS parenchyma, leptomeningeal arteries branch and divide into arterioles. Within the parenchyma, penetrating arterioles and veins are tethered by astrocytes with highly polarized AQP4 distribution, a unique feature of the CNS vasculature. Schematic representation of cross sections of the leptomeningeal vasculature denotes AQP1 and NKCC1 expression by smooth muscle cells, which compose the tunica media of arterioles and veins. In contrast, endothelial cells within the tunica intima are devoid of both proteins. Notwithstanding, endothelial cells of capillaries and venules present both AQP1 and NKCC1

Twenty‐four hours after reperfusion, apoptosis of renal tubular epithelia cells was assessed by immunohistochemical reaction of cleaved‐caspase3. Typical image of cleaved‐caspase3 immunohistochemical staining in renal coronal section from sham, vehicle + I/R and PcTx1+ I/R animal; B, detailed information of immunohistochemical reaction of cleaved‐caspase3 under high‐power lens; ** P < 0.01, compared with sham; ## P < 0.001, compared with vehicle + I/R, n = 6. C, HK‐2 cells were pre‐treated with PcTx1 (100 ng/mL) before H/R treatment, cleaved‐caspase3 was measured by Western blotting; ** P < 0.01, compared with Normoxia; ## P < 0.01, compared with vehicle+H/R, n = 6

Article Title: Acid‐sensing ion channel 1a is involved in ischaemia/reperfusion induced kidney injury by increasing renal epithelia cell apoptosis

doi: 10.1111/jcmm.14238

Figure Lengend Snippet: Schema of I/R induced the local microenvironment acidification and the activation of ASIC1a on renal injury and the involved underlying mechanism. Ischaemia caused accumulation of extracellular protons (H + ). ASIC1a are activated by extracellular H + and induce influx of Ca 2+ , which induced loss of mitochondrial membrane potential. The damage of mitochondrial increased cleaved‐caspase3, which resulted in apoptosis of renal tubular epithelia cells. Administration of the specific inhibitor of ASIC1a, PcTx1 ameliorated ischaemic renal injury by inhibiting ASIC1a, which implied a potential therapeutic choice for AKI
