MPRIN is reported to be involved in multidrug resistance of cancer cells via hyaluronan-mediated activation of ErbB2 signaling and cell survival pathway activities. Bo Wang et al. reported that RNAi-mediated silencing of EMMPRIN promotes tumor sensitivity to cisplatin in a human gastric cancer cell line. Recently, sunitinib was approved for use in mRCC, and the use of sunitinib was demonstrated to have survival benefits. However, most patients treated with sunitinib eventually develop resistance and experience disease progression. In the present study, we investigated whether EMMPRIN affects resistance to sunitinib in RCC. Clinical data showed that after sunitinib therapy, RCC had higher EMMPRIN score, and sunitinib-resistant RCC cells also expressed more EMMPRIN. EMMPRIN overexpressing cells were more resistant to sunitinib. To the best of our knowledge, this is the first evidence that EMMPRIN may be involved in sunitinib resistance. EMMPRIN is highly expressed in human RCC cells, and it plays an important role in their angiogenesis and aggressiveness both in vitro and in vivo. Further studies are warranted to validate that targeting EMMPRIN in RCC inhibits tumor angiogenesis, progression, and resistance to TKIs and mTOR inhibitors. OUR10 cells. VEGF protein was expressed more in conditioned medium than in cell-lysates in 786-O and OUR10 cells. bFGF protein was expressed more in cell-lysates than in conditioned medium in 786-O and OUR10 cells. Conclusions We have shown that the expression level of EMMPRIN in RCC is associated with malignancy, angiogenesis, and prognosis. Silencing EMMPRIN significantly decreased VEGF and bFGF expression, MCT1 colocalization, expression of activated ERK, proliferation, and invasiveness in 25162172 RCC cells. EMMPRIN may also lead to the development of resistance to sunitinib in RCC. Our findings indicate that high expression of EMMPRIN in RCC plays an important role in tumor progression. These data indicate that EMMPRIN may be a novel 12414725 target for the treatment of RCC. Coffin-Lowry syndrome is an X-linked mental retardation disorder caused by mutations in the Rps6ka3 gene, which encodes ribosomal S6 kinase 2. This syndrome is characterized by psychomotor, growth, and cognitive retardation, as well as facial, hand, and MedChemExpress GSK126 skeletal anomalies. CLS patients have markedly reduced cerebellar and hippocampal volumes compared to healthy controls. RSK2 plays a key role in this neurological disorder. In the adult mouse brain, RSK2 is highly expressed in regions with high synaptic activity, including the cerebellar Purkinje cells and the pyramidal cells of the CA3 hippocampal region. Studies have shown that the functional impairment of neurotransmission and plasticity due to AMPAR dysfunction may contribute to the cognitive deficit observed in RSK2 knockout mice. In addition, loss of RSK2 function decreases neurogenesis during cerebral cortex development. These data suggest that RSK2 plays an important role in learning and memory in both humans and mice and that RSK2 deficiency might lead to cognitive and behavioral dysfunction. Several lines of evidence have linked DNA damage and repair systems to neurological disorders. DNA damage can be caused by exogenous or endogenous factors, such as ionizing radiation, chemotherapeutic drugs, and stalled replication forks. Upon exposure to DNA-damage reagents, mammalian cells trigger a sequence of multi-component biochemical reactions to maintain genome integrity. At the core of the si
