View SamplesThe nuclear transmembrane proteins (NETs) NET29/TMEM120A, NET39/PPAPDC3 and NET47/TM7SF2 are able to reposition chromosomes towards/away from the nuclear envelope when overexpressed or knocked down in HT1080 cells. In this study we wanted to investigate the transcriptome changes after transfection of the full length NETs or a nucleoplasmic soluble fragment that does not localise to the nuclear envelope.

High-risk populations include women with diabetes, dyslipidemia, thrombotic disorders, hyperhomocysteinemia, hypertension, renal diseases, previous preeclampsia, twin pregnancies, and low socioeconomic status. In the latter case, the incidence may increase to 20% to 25%. Preeclampsia is a major cause of maternal and fetal morbidity and mortality. Preeclampsia is defined by systolic blood pressure of more than 140 mm Hg and diastolic blood pressure of more than 90 mm Hg after 20 weeks gestation in a previously normotensive patient, and new-onset proteinuria. Abnormal placentation associated with shallow trophoblast invasion (fetal cells from outer cell layer of the blastocyst) into endometrium (decidua) and improper spiral artery remodeling in the decidua are initial pathological steps.

View SamplesThe nuclear envelope transmembrane proteins (NETs) NET39/PPAPDC3, TMEM38A, TMEM214 and WFS1 are expressed or localise preferentially to the nuclear envelope in muscle cells. We knocked these proteins down using specific shRNAs and studied their effect in the diffentiation of the mouse C2C12 myoblast cell line.

View SamplesTumor growth and metastasis is controlled by paracrine signaling between cells of the tumor microenvironment and malignant cells. Cancer-associated fibroblasts (CAFs), are functionally important components of the tumor microenvironment. Although some steps involved in the cross-talk between these cells are known, there is still a lot that is not clear. Thus, the addition of, the consideration of microenvironment in the development of the disease, to the clinical and pathological procedures (currently admitted as the consistent value cancer treatments) could lay the foundations for the development of new treatment strategies to control the disease.

View SamplesPurpose: Evaluate gene expression profiles after inducing differentiation in cultured interstitial cystitis (IC) and control urothelial cells. Materials and Methods: Bladder biopsies were taken from IC patients and controls (women having surgery for stress incontinence). Primary cultures were grown in Keratinocyte Growth Medium with supplements. To induce differentiation, in some plates the medium was changed to DMEM-F12 with supplements. RNA was analyzed with Affymetrix chips. Three nonulcer IC patients were compared with three controls. Results: After inducing differentiation, 302 genes with a described function were altered at least 3-fold with p <0.01 in both IC and control cells. Functions of the162 upregulated genes included cell adhesion (e.g. claudins, occludin, cingulin); urothelial differentiation, retinoic acid pathway and keratinocyte differentiation (e.g. skin cornified envelope components). The 140 downregulated genes included genes associated with basal urothelium (e.g. p63, integrins ?4, ?5 and ?6, basonuclin 1 and extracellular matrix components), vimentin, metallothioneins and members of the Wnt and Notch pathways. Comparing IC vs. control cells after differentiation, only seven genes with a described function were altered at least 3-fold with p <0.01. PI3, SERPINB4, CYP2C8, EFEMP2 and SEPP1 were decreased in IC; AKR1C2 and MKNK1 were increased in IC. Conclusions: Differentiation-associated changes occurred in both IC and control cells. Comparing IC vs. control revealed very few differences. This study may have included IC patients with minimal urothelial deficiency and/or selected the cells that were most robust in culture. Also, the abnormal urothelium in IC may be due to post-translational changes and/or the bladder environment.
