Curcumin ameliorates traumatic brain injury via C1ql3-mediated microglia M2 polarization.

Purpose: Curcumin can regulate the polarization of microglia and alleviate traumatic brain injury (TBI). However, its detailed action mechanism on downregulating Complement 1q-like-3 protein (C1ql3) in TBI is less reported. The purpose of this study is to explore the role and mechanism of curcumin-regulated C1ql3 in TBI.

RNA-Seq Reveals the mRNAs, miRNAs, and lncRNAs Expression Profile of Knee Joint Synovial Tissue in Osteoarthritis Patients.

Osteoarthritis (OA) is a chronic disease common in the elderly population and imposes significant health and economic burden. Total joint replacement is the only currently available treatment but does not prevent cartilage degeneration. The molecular mechanism of OA, especially the role of inflammation in disease progression, is incompletely understood.

MGMT-Mediated neuron Apoptosis in Injured Rat Spinal Cord.

Spinal cord injury (SCI) induces a series of endogenous biochemical changes that lead to secondary degeneration, including apoptosis. The aim of this study was to investigate the potential effect and mechanism of action of MGMT in strengthing neuronal apoptosis following SCI. To determine MGMT-mediated apoptosis in spinal cord injury, we performed western blot and analyzed the expression change of MGMT with different timepoints.

Discovering master regulators in hepatocellular carcinoma: one novel MR, SEC14L2 inhibits cancer cells.

Identification of master regulator (MR) genes offers a relatively rapid and efficient way to characterize disease-specific molecular programs. Since strong consensus regarding commonly altered MRs in hepatocellular carcinoma (HCC) is lacking, we generated a compendium of HCC datasets from 21 studies and identified a comprehensive signature consisting of 483 genes commonly deregulated in HCC. We then used reverse engineering of transcriptional networks to identify the MRs that underpin the development and progression of HCC.

Progesterone Provides the Pleiotropic Neuroprotective Effect on Traumatic Brain Injury Through the Nrf2/ARE Signaling Pathway.

Objective: This study was to investigate the role of Nrf2/ARE signaling pathway in the pleiotropic neuroprotective effect of progesterone (PROG) on traumatic brain injury (TBI).

Methods: The Nrf2-knockout (Nrf2-/-) and C57 mice were respectively subjected to a lateral cortical impact injury caused by a free-falling object and randomly divided into three groups: sham-operated, trauma, and trauma + PROG treatment group. The PROG treatment group was given PROG (32 mg/kg of body weight, intraperitoneal injection) immediately after injury.

Irradiation facilitates the inhibitory effect of the heat shock protein 90 inhibitor NVP-BEP800 on the proliferation of malignant glioblastoma cells through attenuation of the upregulation of heat shock protein 70.

The present study aimed to investigate the effect of NVP-BEP800, a novel heat shock protein (Hsp) 90 inhibitor of the 2-aminothieno[2,3-d]pyrimidine class, in combination with radiation on glioblastoma cells. T98G human glioblastoma cells were treated with dimethyl sulfoxide (DMSO), NVP-BEP800, NVP-BEP800 in combination with X-ray irradiation (10 Gy, 20 min), or X-ray irradiation only, and cultured for 40 h. Cell viability was measured upon completion of the treatments.

[Clinical study on the therapeutic effects and mechanism of progesterone in the treatment for acute severe head injury].

Objective: To evaluate the therapeutic effects of Progesterone (PG) on the patients with acute severe traumatic brain injury, and investigate it's neuroprotective mechanisms.

Methods: Fifth-six patients with acute severe traumatic head injury were divided randomly into two groups: 26 cases were treated with PG and 30 cases were control. Neurological outcome of the patients were assessed using Glasgow Coma Scale (GCS), Glasgow Outcome Scale (GOS), verbal and motor functions scale and Karnofsky Performance Scale (KPS).
