S100A8 accelerates wound healing by promoting adipose stem cell proliferation and suppressing inflammation.

Adipose-derived stem cells (ADSCs) are stem cells with multidirectional differentiation potential isolated from adipose tissue. They have the same immunomodulatory effect as bone marrow mesenchymal stem cells in wound repair and immune regulation as bone marrow. The mechanism of action of ADSCs in skin wound repair has not been elucidated.

[Screening and verification of plasma biomarkers for stable angina pectoris: a differential proteomic analysis].

Objective: To compare and analyze the differentially expressed plasma proteome between patients with stable angina pectoris (SAP) and healthy donors to identify the biomarkers for early diagnosis of SAP.

Methods: Plasma samples from 60 patients with SAP and 60 healthy controls were collected. Twenty samples (100 mL each) randomly selected from each group were pooled and after removing high-abundance proteins from the pooled plasma, two-dimensional gel electrophoresis (2DE) was performed to isolate the total proteins.

Kelch-like Protein 21 (KLHL21) Targets IκB Kinase-β to Regulate Nuclear Factor κ-Light Chain Enhancer of Activated B Cells (NF-κB) Signaling Negatively.

Activation of IKKβ is the key step in canonical activation of NF-κB signaling. Extensive work has provided insight into the mechanisms underlying IKKβ activation through the identification of context-specific regulators. However, the molecular processes responsible for its negative regulation are not completely understood.

Proteomic identification of alpha-2-HS-glycoprotein as a plasma biomarker of hypopharyngeal squamous cell carcinoma.

Hypopharyngeal squamous cell carcinoma (HSCC) has very poor prognosis compared with other head and neck squamous cell carcinomas. Late-stage diagnosis of HSCC increases mortality. Therefore, more effective biomarkers for early diagnosis of HSCC are necessary.

3, 4-dihydroxyl-phenyl lactic acid restores NADH dehydrogenase 1 α subunit 10 to ameliorate cardiac reperfusion injury.

The present study aimed to detect the role of 3, 4-dihydroxyl-phenyl lactic acid (DLA) during ischemia/reperfusion (I/R) induced myocardial injury with emphasis on the underlying mechanism of DLA antioxidant. Male Spragu-Dawley (SD) rats were subjected to left descending artery occlusion followed by reperfusion. Treatment with DLA ameliorated myocardial structure and function disorder, blunted the impairment of Complex I activity and mitochondrial function after I/R.

Acute coronary syndrome remodels the protein cargo and functions of high-density lipoprotein subfractions.

Objectives: This study examined alterations in the functions and proteome of high-density lipoprotein (HDL) subfractions (HDL2 and HDL3) isolated from patients with acute coronary syndrome (ACS) compared with control subjects.

Methods: We measured HDL subfraction cholesterol efflux capacity, inflammatory index (HII), paraoxonase-1 (PON1) activity, and lipid hydroperoxide (LOOH) levels in both male age-matched controls and the ACS group (n = 40/group). Additionally, proteomic analysis was used to monitor changes in the HDL subfraction proteome between controls and ACS subjects.

[Identification of protein markers for gestational diabetes mellitus complicated by pregnancy-induced hypertensive syndrome].

Objective: To identify the serum protein markers for the gestational diabetes mellitus (GDM) complicated by pregnancy-induced hypertensive (PIH) syndrome to provide a molecular biological basis for the screening, prevention and therapy of the related diseases.

Methods: Serum samples were collected from the patients with GDM, PIH syndrome, and GDM complicated by PIH syndrome. IgG and albumins were removed from the samples before SDS -PAGE.

Proteomic analysis of human serum from diabetic retinopathy.

Aim: To establish and compare serum proteomic of diabetic retinopathy (DR) patients in various phases and discuss pathogenesis of DR so as to find out possible serum specific molecular markers for early diagnosis of DR.

Methods: Thirty-two subjects were divided into four groups: one group of eight type 2 diabetes mellitus (T2DM) patients without apparent DR (No-DR, NDR), one group of eight T2DM patients with non-proliferative diabetic retinopathy (NPDR), one group of eight T2DM patients with proliferative diabetic retinopathy (PDR) and one group of eight healthy volunteer participants. Two dimensional fluorescence difference gel electrophoresis (2D-DIGE) was applied to establish differential protein expression profiles in four groups.

[Construction of a eukaryotic expression vector for alpha-1-antitrypsin and the localization of the expression product in NIH 3T3 cells].

Objective: To construct a eukaryotic expression vector for alpha-1-antitrypsin (AAT) and detect its expression and localization in NIH 3T3 cells.

Methods: The total RNA was extracted from the liver tissue of BALB/c mice, and the corresponding coding sequences for mouse AAT (GenBank accession No. NM_009243) were amplified by RT-PCR and cloned into hemagglutinin (HA)-tagged vector pcDNA3-HA.

[Extraction and two-dimensional liquid chromatographic fractionation of plasma membrane proteome of mouse liver cells].

Objective: To extract the plasma membrane proteins from mouse liver cells and investigate the approach for fractionating the protein mixtures by two-dimensional liquid chromatography.

Methods: The plasma membrane of the liver cells from 10 mice was extracted by differential centrifugation and sucrose density-gradient centrifugation. The plasma membrane proteins were exchanged with the start buffer and separated by chromatofocusing in the first-dimensional fractionation.

[Expression and localization of endogenous C-reactive protein in THP-1 monocytes and LO2 hepatocytes].

Objective: To observe the expression and localization of endogenous C-reactive protein (CRP) in cells from different tissues under different conditions.

Methods: Macrophages differentiated from THP-1 monocytes with phorbol ester (PMA) induction and human LO2 hepatocytes were stimulated with lipopolysaccharide (LPS). The culture supernatant of the LPS-stimulated THP-1 cells was collected and added into LO2 cell culture, and after incubation, the cells were lysed to extract the proteins for SDS-PAGE and Western blotting.
