Cytoplasmic Increase in Hsp70 Protein: A Potential New Biomarker of Early Infiltration of Cutaneous Squamous Cell Carcinoma Arising from Actinic Keratosis.

Background: Cutaneous squamous skin cell carcinoma (SCC) is the second most frequent type of non-melanoma skin cancer and is the second leading cause of death by skin cancer in Caucasian populations. However, at present it is difficult to predict patients with poor SCC prognosis.

Objective: To identify proteins with expression levels that could predict SCC infiltration in SCC arising from actinic keratosis (SCC-AK).

Effect of Pectin on the Expression of Proteins Associated with Mitochondrial Biogenesis and Cell Senescence in HT29-Human Colorectal Adenocarcinoma Cells.

Mitochondria dynamic is regulated by different proteins, maintaining a balance between fission and fusion. An imbalance towards mitochondrial fission has been associated with tumor cell proliferation. The aim of this study was to analyze whether pectin modifies the viability of human colon cancer cells and the expression of proteins involved in mitochondrial fusion and fission.

Chronic hydroxychloroquine improves endothelial dysfunction and protects kidney in a mouse model of systemic lupus erythematosus.

Hydroxychloroquine has been shown to be efficacious in the treatment of autoimmune diseases, including systemic lupus erythematosus. Hydroxychloroquine-treated lupus patients showed a lower incidence of thromboembolic disease. Endothelial dysfunction, the earliest indicator of the development of cardiovascular disease, is present in lupus.

Inhibition of acyl-CoA cholesterol acyltransferase by F12511 (Eflucimibe): could it be a new antiatherosclerotic therapeutic?

Lipid-lowering strategies, particularly with statins, have been extremely useful in the prevention of cardiovascular disease. However, many patients who receive statin monotherapy do not achieve the desired cardiovascular benefits. Accumulation of cholesteryl esters within macrophages constitutes the hallmark of foam cells during atherogenesis.

Effects of coronary prestenting platelet inhibition on coronary poststenting inflammation.

The aim of this study was to analyze the effect of 2 antiplatelet regimens on the inhibition of GP IIb/IIIa-dependent platelet activation and their association with the poststenting inflammatory response. Seventeen patients with acute myocardial infarction were divided into 2 groups: (A) clopidogrel plus tirofiban infusion administered together during inclusion (n = 10); (B) clopidogrel administered at inclusion and followed 2 hours after by tirofiban (n = 7). Blood samples were obtained at inclusion and at 24 and 48 hours after stenting.
