The cancer-retina antigen recoverin as a potential biomarker for renal tumors.

The renal cell carcinoma is the ninth most common cancer with an increasing occurrence and mortality. Recoverin is the first retina-specific photoreceptor protein that was shown to undergo aberrant expression, due to its promoter demethylation, as a cancer-retina antigen in a number of malignant tumors. In this work, we demonstrated that recoverin is indeed expressed in 68.

[Glomerulopathy with fibrillary and tubular deposits].

The advent of up-to-date electron microscopes and molecular biological methods for the examination of renal puncture biopsies could define earlier undetectable and unworthy cellular structures and stromas. There is a diversity of diseases that can be diagnosed exclusively at the ultrastructural level, thus the literature has identified the concept of glomerular diseases with organized deposits. The current classifications based only on the ultrastructual deposits are imperfect as they fail to account for the etiological and pathogenetic features included in these diseases.

[Role of tubulin in the pathogenesis of fibrillary glomerulonephritis].

Fibrillary glomerulonephritis is a disease from a group of glomerular diseases with organized deposits. Its etiology and pathogenesis have not been studied. The paper deals with the clinical, morphological, immunohistochemical, and electron microscopic studies of 45 patients with fibrillary glomerulonephritis.

[Fibrillary glomerulonephritis and immunotactoid nephropathy: the current view of the pathomorphological substrate of disease].

Fibrillary glomerulonephritis (FGN) and immunotactoid nephropathy (ITN) are diseases diagnosed only by electron microscopy. Until recently, information on the diseases has reached as reports on some cases. Much information, including the authors' observations, has been presently gathered so as there is a chance of attempting to pool and analyze it.
