Pro-inflammatory cytokines/chemokines, TNF-α, IL-6 and MCP-1, as biomarkers for the nephro- and pneumoprotective effect of silibinin after hepatic ischemia/reperfusion: Confirmation by immunohistochemistry and qRT-PCR.

The present study investigated the potential nephro- and pneumoprotective effect of silibinin (Si) after hepatic ischemia-reperfusion (I/R) injury, by measuring pro-inflammatory factors. Sixty-three rats were randomly assigned into three groups, as follows: (a) the sham group (n = 7 rats), subjected to opening and closing the abdomen; (b) the control group (n = 28 rats), subjected to 45-min hepatic ischemia followed by reperfusion; and (c) the silibinin group (n = 28), subjected to 45-min hepatic ischemia followed by intravenous administration of lyophilised SLB-HP-β-CD before reperfusion. Control and silibinin groups were further subdivided into time-point groups, according to the duration of reperfusion.

Effect of silibinin on the expression of MMP2, MMP3, MMP9 and TIMP2 in kidney and lung after hepatic ischemia/reperfusion injury in an experimental rat model.

Purpose: The protective effect of silibinin on kidney and lung parenchyma during hepatic ischemia/reperfusion injury (IRI) is explored.

Methods: Sixty-three Wistar rats were separated into three groups: sham; control (45 min IRI); and silibinin (200 μL silibinin administration after 45 min of ischemia and before reperfusion). Immunohistochemistry and real-time quantitative reverse transcription polymerase chain reaction (qRT-PCR) were used to evaluate the expression levels of MMP2, MMP3, MMP9, and TIMP2 on kidney and lung.

The hepatoprotective effect of silibinin after hepatic ischemia/reperfusion in a rat model is confirmed by immunohistochemistry and qRT-PCR.

Objectives: We investigated the positive effect of silibinin after IV administration as silibinin-hydroxypropyl-β-cyclodextrin lyophilized product, by measuring gene expression and liver tissue protein levels of tumor necrosis factor-α, interleukin-6, monocyte chemoattractant protein-1, matrix metalloproteinases matrix metalloproteinases and tissue inhibitor of matrix metalloproteinases-2.

Methods: 63 Wistar rats of age 13.24±4.

Deep-proteome mapping of WM-266-4 human metastatic melanoma cells: From oncogenic addiction to druggable targets.

Cutaneous melanoma is a malignant tumor of skin melanocytes that are pigment-producing cells located in the basal layer (stratum basale) of epidermis. Accumulation of genetic mutations within their oncogenes or tumor-suppressor genes compels melanocytes to aberrant proliferation and spread to distant organs of the body, thereby resulting in severe and/or lethal malignancy. Metastatic melanoma's heavy mutational load, molecular heterogeneity and resistance to therapy necessitate the development of novel biomarkers and drug-based protocols that target key proteins involved in perpetuation of the disease.

Mining of relations between proteins over biomedical scientific literature using a deep-linguistic approach.

Objective: The amount of new discoveries (as published in the scientific literature) in the biomedical area is growing at an exponential rate. This growth makes it very difficult to filter the most relevant results, and thus the extraction of the core information becomes very expensive. Therefore, there is a growing interest in text processing approaches that can deliver selected information from scientific publications, which can limit the amount of human intervention normally needed to gather those results.

The dual role of chorion peroxidase in Bactrocera oleae chorion assembly.

In the present study, we reveal for the first time that the Bactrocera oleae chorion peroxidase (bPxd) participates essentially in B. oleae chorion formation and clearly represents the homologous member of Drosophila melanogaster chorion peroxidase (Pxd). Comparative sequence analysis disclosed that the bPxd cDNA semi-central region, which encodes for the putative catalytic domain of the enzyme, exhibits great homology (98%) with its Pxd counterpart.

The enzymatic component of Drosophila melanogaster chorion is the Pxd peroxidase.

In the present study, we demonstrate the isolation and characterization of the Pxd cDNA clone, which codes for the Drosophila melanogaster chorion peroxidase. This specific peroxidase is involved in the chorion hardening process, through protein crosslinking mediated by the formation of di- and tri-tyrosine bonds. The Pxd gene product has been identified in crude protein extracts from adult flies as three immunoreacting, with the anti-rAePO polyclonal antibody, bands of 77, 67 and 55 kDa, while in larvae and purified chorions as a unique 55 kDa band.
