Classes of non-conventional tetraspanins defined by alternative splicing

2019

AbstractTetraspanins emerge as a family of membrane proteins mediating an exceptional broad diversity of functions. The naming refers to their four transmembrane segments, which define the tetraspanins‘ typical membrane topology. In this study, we analyzed alternative splicing of tetraspanins. Besides isoforms with four transmembrane segments, most mRNA sequences are coding for isoforms with one, two or three transmembrane segments, representing structurally mono-, di- and trispanins. Moreover, alternative splicing may alter transmembrane topology, delete parts of the large extracellular loop, or generate alternative N- or C-termini. As a result, we define structure-based classes of non-con…

Toxicogenomics for the prediction of toxicity related to herbs from traditional Chinese medicine.

2010

Toxicogenomics represents the integration of genomics and toxicology to investigate the interaction between genes and environmental stress in human health. It is a scientific field that studies how the genome is involved in responses to environmental stressors and toxicants. The patterns of altered gene expression that are caused by specific exposures or disease outcomes reveal how toxicants may act and cause disease. Nowadays, toxicogenomics faces great challenges in discriminating the molecular basis of toxicity. We do believe that advances in this field will eventually allow us to describe all the toxicological interactions that occur within a living system. Toxicogenomic responses of a …

Small-sample characterization of stochastic approximation staircases in forced-choice adaptive threshold estimation

2007

Despite the widespread use of up—down staircases in adaptive threshold estimation, their efficiency and usability in forced-choice experiments has been recently debated. In this study, simulation techniques were used to determine the small-sample convergence properties of stochastic approximation (SA) staircases as a function of several experimental parameters. We found that satisfying some general requirements (use of the accelerated SA algorithm, clear suprathreshold initial stimulus intensity, large initial step size) the convergence was accurate independently of the spread of the underlying psychometric function. SA staircases were also reliable for targeting percent-correct levels far …

Pterostilbene-induced tumor cytotoxicity: a lysosomal membrane permeabilization-dependent mechanism.

2012

The phenolic phytoalexin resveratrol is well known for its health-promoting and anticancer properties. Its potential benefits are, however, limited due to its low bioavailability. Pterostilbene, a natural dimethoxylated analog of resveratrol, presents higher anticancer activity than resveratrol. The mechanisms by which this polyphenol acts against cancer cells are, however, unclear. Here, we show that pterostilbene effectively inhibits cancer cell growth and stimulates apoptosis and autophagosome accumulation in cancer cells of various origins. However, these mechanisms are not determinant in cell demise. Pterostilbene promotes cancer cell death via a mechanism involving lysosomal membrane …

Elderly Parents’ Need for Help and Adult Children's Moving Decisions

2015

Recent changes in Finnish welfare policies have increased the need for family involvement in eldercare. This article uses qualitative interviews to study working adult daughters’ reasons for moving in with their parent(s). Coresidence was linked to the parents’ need for support, but also to the daughters’ life situations, family histories, the availability of welfare services, and cultural norms and values. The interviewees used the “familist” and “independent life” discourses in their speech. The familist discourse was used to argue for coresidence as a natural continuation of family traditions and life history, whereas the independent life discourse was used to legitimize the need for alt…
