Abstract

Human myoblasts express immunological properties in vitro and we have previously reported that they produce Complement (C) components of the alternative pathway. Myoblasts activate the classical pathway but are fully protected against C attack by the expression of major C regulators. In order to fully understand the relationship between myoblasts and C, we here report the biosynthesis of C components of the classical pathway by skeletal muscle cells. Human myoblasts in vitro produced C1q, C1r, C1s, C2 and C4 constitutively and all syntheses were upregulated after stimulation with IFN-gamma. We suggest that human myoblasts may constitute a local source of C and therefore C could be implicated in inflammatory or physiopathological processes developed in skeletal muscle.

The nontoxic cell cycle modulator indirubin augments transduction of adeno-associated viral vectors and zinc-finger nuclease-mediated gene targeting.

Parameters that regulate or affect the cell cycle or the DNA repair choice between non-homologous end-joining and homology-directed repair (HDR) are excellent targets to enhance therapeutic gene targeting. Here, we have evaluated the impact of five cell-cycle modulating drugs on targeted genome engineering mediated by DNA double-strand break (DSB)-inducing nucleases, such as zinc-finger nucleases (ZFNs). For a side-by-side comparison, we have established four reporter cell lines by integrating a mutated EGFP gene into either three transformed human cell lines or primary umbilical cord-derived mesenchymal stromal cells (UC-MSCs). After treatment with different cytostatic drugs, cells were transduced with adeno-associated virus (AAV) vectors that encode a nuclease or a repair donor to rescue EGFP expression through DSB-induced HDR. We show that transient cell-cycle arrest increased AAV transduction and AAV-mediated HDR up to six-fold in human cell lines and ten-fold in UC-MSCs, respectively. Targeted gene correction was observed in up to 34% of transduced cells. Both the absolute and the relative gene-targeting frequencies were dependent on the cell type, the cytostatic drug, the vector dose, and the nuclease. Treatment of cells with the cyclin-dependent kinase inhibitor indirubin-3'-monoxime was especially promising as this compound combined high stimulatory effects with minimal cytotoxicity. In conclusion, indirubin-3'-monoxime significantly improved AAV transduction and the efficiency of AAV/ZFN-mediated gene targeting and may thus represent a promising compound to enhance DSB-mediated genome engineering in human stem cells, such as UC-MSCs, which hold great promise for future clinical applications.

Polymorphic gene regulation and interindividual variation of UDP-glucuronosyltransferase activity in human small intestine.

UDP-glucuronosyltransferases (UGTs) convert dietary constituents, drugs, and environmental mutagens to inactive hydrophilic glucuronides. Recent studies have shown that the expression of the UGT1 and UGT2 gene families is regulated in a tissue-specific fashion. Human small intestine represents a major site of resorption of dietary constituents and orally administered drugs and plays an important role in extrahepatic UGT directed metabolism. Expression of 13 UGT1A and UGT2B genes coupled with functional and catalytic analyses were studied using 18 small intestinal and 16 hepatic human tissue samples. Hepatic expression of UGT gene transcripts was without interindividual variation. In contrast, a polymorphic expression pattern of all the UGT genes was demonstrated in duodenal, jejunal, and ileal mucosa, with the exception of UGT1A10. To complement these studies, interindividual expression of UGT proteins and catalytic activities were also demonstrated. Hyodeoxycholic acid glucuronidation, catalyzed primarily by UGT2B4 and UGT2B7, showed a 7-fold interindividual variation in small intestinal duodenal samples, in contrast to limited variation in the presence of 4-methylumbelliferone, a substrate glucuronidated by most UGT1A and UGT2B gene products. Linkage of RNA expression patterns to protein abundance were also made with several mono-specific antibodies to the UGTs. These results are in contrast to a total absence of polymorphic variation in gene expression, protein abundance, and catalytic activity in liver. In addition, the small intestine exhibits considerable catalytic activity toward most of the different classes of substrates accepted for glucuronidation by the UGTs, which is supported by immunofluorescence analysis of UGT1A protein in the mucosal cell layer of the small intestine. Thus, tissue-specific and interindividual polymorphic regulation of UGT1A and UGT2B genes in small intestine is identified and implicated as molecular biological determinant contributing to interindividual prehepatic drug and xenobiotic metabolism in humans.

The mouse mammary tumor virus promoter adopts distinct chromatin structures in human breast cancer cells with and without glucocorticoid receptor.

Steroid receptors represent a class of transcription regulators that act in part by overcoming the often repressive nature of chromatin to modulate gene activity. The mouse mammary tumor virus (MMTV) promoter is a useful model for studying transcriptional regulation by steroid hormone receptors in the context of chromatin. The chromatin architecture of the promoter prevents the assembly of basal transcription machinery and binding of ubiquitous transcription factors. However, in human breast carcinoma T47D cells lacking the glucocorticoid receptor (GR), but expressing the progesterone receptor (PR), nucleosome B (nuc B) assumes a constitutively hypersensitive chromatin structure. This correlation led us to test the hypothesis that the chromatin structure of nuc B was dependent on GR expression in T47D cells. To examine this possibility, we stably co-transfected the MMTV promoter and the GR into T47D cells that lacked both the GR and the PR. We found that in T47D cells that lack both the GR and the PR or express only the GR, nuc B assumes a constitutively "open" chromatin structure, which allows hormone independent access by restriction endonucleases and transcription factors. These results suggest that in GR(+)/pr(-) T47D cells, the MMTV chromatin structure permits GR transcriptional activation, independent of chromatin remodeling.
