The RNA sequencing results revealed the expression of different genes and signaling pathways during chemotherapy resistance in peripheral T-cell lymphoma.

Background: Peripheral T-cell lymphoma (PTCL) is a subtype of non-Hodgkin's lymphoma that occurs primarily at extranodal sites and is commonly treated using chemotherapy and radiotherapy. PTCL is more malignant than other lymphoid tumors, resulting in a poor prognosis.The 5-year recurrence rate remains high, and there is a lack of standard treatment for patients with relapse-resistant disease.

Early Growth Response Gene-1 Deficiency Interrupts TGFβ1 Signaling Activation and Aggravates Neurodegeneration in Experimental Autoimmune Encephalomyelitis Mice.

Early growth response protein 1 (Egr-1) triggers the transcription of many genes involved in cell growth, differentiation, synaptic plasticity, and neurogenesis. However, its mechanism in neuronal survival and degeneration is still poorly understood. This study demonstrated that Egr-1 was down-regulated at mRNA and protein levels in the central nervous system (CNS) of experimental autoimmune encephalomyelitis (EAE) mice.

Mutational characteristics of Chinese Han and ethnic minorities in southwestern China: a propensity score matched analysis.

Background: In China, there has never been a comprehensive analysis of lung cancer-associated genetic mutations focused on ethnic minorities in the southwestern region. Our study aimed to provide valuable information on lung cancer-associated genetic alterations for cancer diagnosis and treatment, especially in ethnic minorities.

Methods: Retrospective data acquisition was conducted spanning 3 years (2016.

Modafinil protects hippocampal neurons by suppressing excessive autophagy and apoptosis in mice with sleep deprivation.

Background And Purpose: Sleep deprivation compromises learning and memory in both humans and animals, and can be reversed by administration of modafinil, a drug promoting wakefulness. Dysfunctional autophagy increases activation of apoptotic cascades, ultimately leading to increased neuronal death, which can be alleviated by autophagy inhibitors. This study aimed to investigate the alleviative effect and mechanism of modafinil on the excessive autophagy occurring in the hippocampus of mice with deficiency of learning and memory induced by sleep deprivation.

P-glycoprotein Inhibitor Tariquidar Potentiates Efficacy of Astragaloside IV in Experimental Autoimmune Encephalomyelitis Mice.

ATP-binding cassette (ABC) transporters, such as P-glycoprotein (P-gp) and breast cancer resistance protein (BCRP), often reduce drug efficacy and are the major cause of drug resistance. Astragaloside IV (ASIV), one of the bioactive saponins isolated from , has been demonstrated to alleviate the progression of experimental autoimmune encephalomyelitis (EAE) in mice, an animal model for multiple sclerosis (MS). In the present study, we found for the first time that ASIV induced the upregulation of P-gp and BCRP in the central nervous system (CNS) microvascular endothelial cells of EAE mice.

Astragaloside IV Promotes Adult Neurogenesis in Hippocampal Dentate Gyrus of Mouse through CXCL1/CXCR2 Signaling.

Astragaloside IV (ASI) has been reported to promote neural stem cells proliferation in vitro and CXCR2 expression on neutrophils. The present study was aimed to investigate the influence of ASI on adult neurogenesis in hippocampal dentate gyrus (DGs) of mouse and to discuss the possible underlying mechanisms. Total number of proliferative cells (BrdU⁺), pre-mature neurons (DCX⁺), early proliferative cells (BrdU⁺/DCX⁺), proliferative radial gila-like cells (BrdU⁺/GFAP⁺) and newly generated neurons (BrdU⁺/NeuN⁺) after ASI or vehicle administration for two weeks were counted, respectively.

Gypenoside IX Suppresses p38 MAPK/Akt/NFκB Signaling Pathway Activation and Inflammatory Responses in Astrocytes Stimulated by Proinflammatory Mediators.

Gypenoside IX (GP IX) is a pure compound isolated from Panax notoginseng. Gypenosides have been implicated to benefit the recovery of enormous neurological disorders. By suppressing the activation of astrocytes, gypenosides can improve the cognitive impairment.

Astragaloside IV improves lipid metabolism in obese mice by alleviation of leptin resistance and regulation of thermogenic network.

Obesity is a worldwide threat to public health in modern society, which may result from leptin resistance and disorder of thermogenesis. The present study investigated whether astragaloside IV (ASI) could prevent obesity in high-fat diet (HFD)-fed and db/db mice. In HFD-fed mice, ASI prevented body weight gain, lowered serum triglyceride and total cholesterol levels, mitigated liver lipid accumulation, reduced fat tissues and decreased the enlargement of adipose cells.

[Inhibitory effects of vina-ginsenoside R7 on activation of rat C6 astrocytes induced by LPS and TNF-α combination].

To investigate the inhibitory effect and mechanism of vina-ginsenoside R7 (R7) on the activation of rat C6 astrocytes cells induced by LPS/TNF-α, cells in logarithmic growth phase were cultured in DMEM medium without FBS for 24 h. After dissociated using 0.25% EDTA-trypsin, the cells were seeded into respective plates at the density of 1.

Astragaloside IV inhibits microglia activation via glucocorticoid receptor mediated signaling pathway.

Inhibition of microglia activation may provide therapeutic treatment for many neurodegenerative diseases. Astragaloside IV (ASI) with anti-inflammatory properties has been tested as a therapeutic drug in clinical trials of China. However, the mechanism of ASI inhibiting neuroinflammation is unknown.

Deletion of mouse FXR gene disturbs multiple neurotransmitter systems and alters neurobehavior.

Farnesoid X receptor (FXR) is a nuclear hormone receptor involved in bile acid synthesis and homeostasis. Dysfunction of FXR is involved in cholestasis and atherosclerosis. FXR is prevalent in liver, gallbladder, and intestine, but it is not yet clear whether it modulates neurobehavior.
