Structural and Hereditary Chaperonopathies: Mutation
2013
This chapter deals with structural and hereditary chaperonopathies. The chaperonopathies caused by mutations in: sHsp, chaperonin genes (Hsp60 or Cpn60, and CCT subunits), Hsp40/DnaJ, Hsp70, sacsin, and dedicated chaperones (e.g., those involved in microtubule biogenesis, in maintenance of the respiratory chain inside the mitochondria, and others in various cell compartments and tissues), are described and discussed.
Effect of two xeno-hormones, genistein and vinclozolin on development and exocrines and endocrines functions of submandibular salivary glands of Wist…
2012
The salivary glands are mixed glands: saliva (exocrine product) is involved inmaintaining oral homeostasis whereas endocrine secretions (eg growth factors) have aphysiological role (gametogenesis, osteogenesis, hypertension ..). In mammals, they displaysexual dimorphism suggesting a possible susceptibility to xeno-hormones.This manuscript presents the action of genistein (phytoestrogen) and/or vinclozolin (antiandrogenic)on the submandibular gland (SM) rats when performing an early exposure via themother (pregnancy, lactation) or an exposure during the growth period (from weaning toadulthood). The SM glands, collected at immature and young adult ages, have been analyzedaccording histologica…

Tubular markers do not predict the decline in glomerular filtration rate in type 1 diabetic patients with overt nephropathy.
2011
Recent studies have shown that both glomerular and tubulointerstitial damage are important factors in the pathophysiology and progression of diabetic nephropathy. To examine whether markers of tubular damage are useful in monitoring the progression of disease, we measured urinary levels of neutrophil gelatinase-associated lipocalin (NGAL), liver-fatty acid-binding protein (LFABP), and kidney injury molecule-1 (KIM-1) in a 3-year intervention study of 63 type 1 diabetic patients with kidney disease. The baseline mean glomerular filtration rate (GFR) was 87 ml/min per 1.73 m(2) and urinary albumin excretion 1141 mg/24 h. Patients with the highest compared with the lowest quartile of urinary N…
Caki-1 cells as a model system for the interaction of renally secreted drugs with OCT3.
2008
<i>Background/Aims:</i> Organic cation transporters (OCT) in the proximal tubules (PTs) participate in the renal secretion of several therapeutic agents. The exact role of OCT3 in renal secretion remains undetermined, partially due to the lack of an appropriate in vitro model system. The current work introduces the PT representative cell line, Caki-1, as a model system for studying the involvement of OCT3 in renal secretion. <i>Methods:</i> Caki-1 cells were characterized for OCT3 expression via real-time RT-PCR and immunocytochemical staining techniques. Uptake kinetics of OCT3 in Caki-1 cells was determined using prototypical substrates and inhibitors. Inhibition o…

Microtubule Dynamics and Neuronal Excitability: Advances on Cytoskeletal Components Implicated in Epileptic Phenomena
2020
AbstractExtensive researches have deepened knowledge on the role of synaptic components in epileptogenesis, but limited attention has been devoted to the potential implication of the cytoskeleton. The study of the development of epilepsy and hyperexcitability states involves molecular, synaptic, and structural alterations of neuronal bioelectric activity. In this paper we aim to explore the neurobiological targets involved in microtubule functioning and cytoskeletal transport, i.e. how dynamic scaffolding of microtubules can influence neuronal morphology and excitability, in order to suggest a potential role for microtubule dynamics in the processes turning a normal neuronal network in a hy…
Polymorphisms in DCDC2 and S100B associate with developmental dyslexia
2015
Genetic studies of complex traits have become increasingly successful as progress is made in next-generation sequencing. We aimed at discovering single nucleotide variation present in known and new candidate genes for developmental dyslexia: CYP19A1, DCDC2, DIP2A, DYX1C1, GCFC2 (also known as C2orf3), KIAA0319, MRPL19, PCNT, PRMT2, ROBO1 and S100B. We used next-generation sequencing to identify single-nucleotide polymorphisms in the exons of these 11 genes in pools of 100 DNA samples of Finnish individuals with developmental dyslexia. Subsequent individual genotyping of those 100 individuals, and additional cases and controls from the Finnish and German populations, validated 92 out of 111 …
Analysis of the infectious entry pathway of human papillomavirus type 33 pseudovirions.
2002
AbstractHuman papillomavirus type 33 (HPV-33) pseudovirus infection is a slow process dependent on the initial interaction with cell-surface heparan sulfate (T. Giroglou, L. Florin, F. Schafer, R. E. Streeck, and M. Sapp, 2001a, J. Virol. 75, 1565–1570). We have now further dissected the initial steps of pseudovirus uptake using removal of cell-surface proteoglycans and selective inhibition of entry pathways. Treatment of cells with heparinase I, but not with phosphoinositol-specific phospholipase C (PIPLC), prevented binding of papillomavirus-like particles and infection with HPV-33 pseudovirions, indicating that GPI-linked proteoglycans (glypicans) are not required for productive infectio…
