RESUMEN
Distant metastasis is one of the main obstacles to cancer treatment.Overexpression of S1PR1 in malignant tumors enhances cell invasion and migration activity,mediates EMT and induces lymphangiogenesis and angiogenesis via activation of its downstream signaling pathways,eventually results in the occurrence of tumor metastasis.S1PR1 is also closely related to generation of acquired radiotherapy resistance.This article discusses the roles of S1PR1 in tumor metastasis and radiotherapy resistance.
RESUMEN
Hepatocellular carcinoma (HCC) and liver failure are common liver diseases in China and have extremely high incidence and mortality rates. Although there are many related studies, the detailed pathogenesis of these two diseases is still unknown. This article reviews the role of STAT1 and STAT3 phosphorylation proteins in the pathogenesis of HCC and liver failure, such as antiviral defense, acute phase response, liver injury, repair, inflammation, and transformation. A deep understanding of their role in the pathogenesis of HCC and liver failure and the development of related drugs with them as molecular targets play an important role in reducing mortality rate in clinical practice.
RESUMEN
Depression is one of the prevalent causes of health-related human suffering and is,first and foremost,a disorder of one of the least-studied biological phenomena:emotion.Therefore,it is critically important to understand emotion,in order to understand the etiology of depression.Chinese medicine is the oldest subject about emotion,has developed a theory about basic emotions and their interactions,and also their roles in causes and therapy in most of human diseases,including mental disorders,such as depression.Nowadays,major depressive disorder (MDD) is a prevalent mental disorder with cognitive,affective and behavioral symptoms,and has been identified as a leading cause of disability,and affecting about ～17％ of the populations worldwide.Decades of animal and clinical studies have pointed its etiology in dysfunctions in the monoamine transporters.Here we will review some literatures about the relationship between the monoamine neuromodulators and emotional theory in Chinese medicine,which might introduce theoretical perspectives in studies about emotion and depression.
RESUMEN
Acute - on - chronic liver failure (ACLF)is commonly seen in China,with a complex pathogenesis,difficult clinical treatment, and poor prognosis. Many factors can affect the prognosis of patients with ACLF. This article elaborates on the changes in immune cells and cytokines in ACLF and their influence on the prognosis of ACLF,in order to explore new biomarkers associated with the prognosis of ACLF, provide guidance for clinical treatment,and finally improve the prognosis of patients with ACLF.
RESUMEN
Inflammation response is the most crucial link in the pathogeneses of spinal cord injury (SCI),and is the basis of secondary damage. NF-κB Signalling pathway is activated excessively after SCI,so that numerous NF-κB possessing biological activities is quickly translocated into the nuclear and regulates the target genes,resulting in heightened inflammation and further tissue damage. Suppressing NF-κB signalling pathway and controlling inflammation response effectively are effective approaches to promoting SCI repair. It is found that curcumin has multiple target molecules to suppress NF-κB signalling pathway,block the excessive activation of NF-κB and reduce the expression of proinflammation cytokines,which plays an important role in SCI repair. This article discusses NF-κB signalling pathway,the contribution of NF-κB signalling pathway to SCI and the role of curcumins inhibition of NF-κB signalling pathway in SCI.
