Open AccessCombination of lenalidomide with vitamin D3 induces apoptosis in mantle cell lymphoma via demethylation of BIK
Mantle cell lymphoma (MCL) is a currently incurable B-cell malignancy. Lenalidomide (Len) has been demonstrated to be one of the most efficient new treatment options. Because Len and 1α,25-dihydroxyvitamin (VD...

Increase in HLA-G1 proteolytic shedding by tumor cells: a regulatory pathway controlled by NF-κB inducers
HLA-G is expressed by tumors, in which it contributes to the evasion of immunosurveillance. NF-κB appears to be a candidate for regulating HLA-G expression, since it is considered to be a hallmark of cancer. W...

Article
HLA-G protein processing and transport to the cell surface
Data are presented on the intracellular trafficking of HLA-G protein, taking the unique features of this non-classical molecule into consideration: the existence of seven isoforms resulting from alternative s...

Potentiation of Fas-mediated apoptosis by an engineered glycosylphosphatidylinositol-linked Fas
FasL and TRAIL are apoptotic ligands of the TNF-like cytokines family, acting via activation of the transmembrane death domain containing receptors Fas for FasL, and DR4 or DR5 for TRAIL. A glycosylphosphatidy...

Altered HLA-G transcription in pre-eclampsia is associated with allele specific inheritance: possible role of the HLA-G gene in susceptibility to the disease
Pre-eclampsia is a disorder of human pregnancy occuring in 5-10 % of all births, and represents the leading cause of infant morbidity and mortality and maternal death. In pre-eclampsia, invasion of fetal trop...

Lipid Traffic to the Plasma Membrane of Leek Cells. Sorting Based on Fatty Acyl Chain Length
The mechanisms by which lipids are sorted and transferred to the plasma membrane are poorly understood as compared to the situation of glyco- proteins but are now under intense investigations particularly in a...

Acyl Transfer Reactions Associated with Cis Golgi Apparatus
Recent work in our laboratory involving cell-free lipid transfer from transitional endoplasmic reticulum (ER) to Golgi apparatus has shown a latent phospholipase A activity localized in the cis Golgi of rat li...

Article
Cell-free transfer and sorting of membrane lipids in spinach
The donor and acceptor specificity of cell-free transfer of radiolabeled membrane constituents, chiefly lipids, was examined using purified fractions of endoplasmic reticulum, Golgi apparatus, nuclei, plasma m...

Cell-free transfer of sterols from dictyosome-like structures to plasma membrane vesicles of guinea pig testes
Transfer of radiolabeled lipids from dictyosome-like structures (DLS) from testis tubules of the guinea pig as donor to unlabeled plasma membrane from testis tubules immobilized on nitrocellulose as acceptor w...

Plasma Membrane Biogenesis in Higher Plants: The Lipid Routes
The study of the biogenesis of the plasma membrane in higher plants has lagged behind that of animal cells, though the endomembrane concept, as well as the indications concerning the membrane traffic, resulted...

Monensin: A Tool to Study Intracellular Transport of Lipids in Higher Plants
The biogenesis of the plasma membrane has been extensively studied in both animal and plant cells by following the biosynthesis, maturation and intracellular transport of glycoproteins. However, little is yet ...

Study of the Intracellular Transfer of Lipids to the Plasmalemma
It has been shown in vitro that in leek (Allium porrum L.) epidermis cells very long chain fatty acids (VLCFA) are synthesized in the endoplasmic reticulum.1 Moreover, VLCFA are more abundant in the plasma membra...
