The potential of TRP channels as new prognostic and therapeutic targets against prostate cancer progression.

Prostate cancer (PCa) is the second deadliest cancer among men worldwide. Particularly critical is its development towards metastatic androgen-independent forms for which the current therapies are ineffective. Indeed, the 5-year relative survival for PCa drops dramatically to 34 % in the presence of metastases.

Osteoblast Response to Widely Ranged Texturing Conditions Obtained through High Power Laser Beams on Ti Surfaces.

Titanium and titanium alloys are the prevailing dental implant materials owing to their favorable mechanical properties and biocompatibility, but how roughness dictates the biological response is still a matter of debate. In this study, laser texturing was used to generate eight paradigmatic roughened surfaces, with the aim of studying the early biological response elicited on MC3T3-E1 pre-osteoblasts. Prior to cell tests, the samples underwent SEM analysis, optical profilometry, protein adsorption assay, and optical contact angle measurement with water and diiodomethane to determine surface free energy.

Dysregulation of FLVCR1a-dependent mitochondrial calcium handling in neural progenitors causes congenital hydrocephalus.

Congenital hydrocephalus (CH), occurring in approximately 1/1,000 live births, represents an important clinical challenge due to the limited knowledge of underlying molecular mechanisms. The discovery of novel CH genes is thus essential to shed light on the intricate processes responsible for ventricular dilatation in CH. Here, we identify FLVCR1 (feline leukemia virus subgroup C receptor 1) as a gene responsible for a severe form of CH in humans and mice.

Modulation of purinergic signaling in endothelial cells by tumor microenvironment.

Purinergic signaling plays a crucial role in vascular endothelium functions. In particular, ionotropic P2X receptors (P2XRs) are engaged in various intracellular pathways through which endothelial cells (ECs) adapt to external stimuli. However, very little is known about the impact of P2XRs on vascular remodeling during carcinogenesis.

The Emerging Concept of Transportome: State of the Art.

The array of ion channels and transporters expressed in cell membranes, collectively referred to as the transportome, is a complex and multifunctional molecular machinery; in particular, at the plasma membrane level it finely tunes the exchange of biomolecules and ions, acting as a functionally adaptive interface that accounts for dynamic plasticity in the response to environmental fluctuations and stressors. The transportome is responsible for the definition of membrane potential and its variations, participates in the transduction of extracellular signals, and acts as a filter for most of the substances entering and leaving the cell, thus enabling the homeostasis of many cellular parameters. For all these reasons, physiologists have long been interested in the expression and functionality of ion channels and transporters, in both physiological and pathological settings and across the different domains of life.
