Functional Significance of Cell Volume Regulatory Mechanisms

The current status of the use of nanoparticles for photothermal treatments is reviewed in detail. The different families of heating nanoparticles are described paying special attention to the physical mechanisms at the root of the light-to-heat conversion processes. The heating efficiencies and spectral working ranges are listed and compared. The most important results obtained in both in vivo and in vitro nanoparticle assisted photothermal treatments are summarized. The advantages and disadvantages of the different heating nanoparticles are discussed.

Transgenerational Epigenetic Inheritance: myths and mechanisms

DNA methylation is a defining feature of mammalian cellular identity and essential for normal development 1,2 . Most cell types, except germ cells and pre-implantation embryos 3–5 , display relatively stable DNA methylation patterns with 70–80% of all CpGs being methylated 6 . Despite recent advances we still have a too limited understanding of when, where and how many CpGs participate in genomic regulation. Here we report the in depth analysis of 42 whole genome bisulfite sequencing (WGBS) data sets across 30 diverse human cell and tissue types. We observe dynamic regulation for only 21.8% of autosomal CpGs within a normal developmental context, a majority of which are distal to transcription start sites. These dynamic CpGs co-localize with gene regulatory elements, particularly enhancers and transcription factor binding sites (TFBS), which allow identification of key lineage specific regulators. In addition, differentially methylated

The in vitro interactions between human osteosarcoma (HOS) cells and platelets were studied in real time using video-enhanced microscopy. Interference reflection techniques showed that platelets were lysed within minutes after contacting HOS cells that had been treated with interferon-gamma. Untreated HOS cells lysed platelets less efficiently. Platelet lysis depended on platelet-tumor cell contact and on extracellular Ca2+. A number of possible mechanisms were excluded. Lysis of platelets in proximity to tumor cells can provide these with growth factors and thereby contribute to the metastasis-enhancing effect of platelets.
