We suspect that the correlations we observe between Abd-B expression and the amount of transvection at Men are the result of similar modulation of chromosomal architecture altering somatic chromosomal pairing in response to temperature-, and possibly genetic background-, driven changes in Abd-B expression.
The regulation of SIRT1 protein levels by miRNAs might provide new opportunities for therapeutic tissue-specific modulation of SIRT1 expression and for reprogramming of somatic cells into iPS cells.
Based on these findings, we hypothesized that modulation of arterial baroreflex function by somatic afferents is mediated by NK1-R dependent inhibition of barosensitive NTS circuits.
In fact such experiments can also provide phenomenological evidence for the modulation of synaptic plasticity by the somatic potential, or at least by a low-pass filtered version thereof.
In the current investigation, we focused on determining the impact of TSA-dependent epigenomic modulation of cultured MSCs on the somatic cell cloning efficiency measured with in vitro developmental capability of NT pig embryos and their cytological quality at the blastocyst stage that was evaluated on the basis of both total blastomere number and apoptotic index estimated by TUNEL analysis.
Taken together, present data highlight the modulation of hundreds of genes in the somatic components of KS patient testis.
In summary, there seems to be a two-tiered compensatory response to loss of DNA repair in C. elegans: While lack of either BER or NER results in activation of genes responding to endogenous stressors and suppression of ILS, lack of both BER and NER shifts the transcriptional response to reduction of proliferation and somatic preservation through modulation of AIR-2 and PLK-1 signaling networks.
If we can confirm that a similar mechanism operates for human and murine BM-derived UCB-VSELs, perhaps a controlled modulation of the somatic imprinted state to produce proper de novo methylation of somatic imprinted genes on the maternal and paternal chromosomes could increase the regenerative power of these cells.
Collectively, these data suggest that cytokinin degradation and sequestration may be important in the modulation of cell division pace and hint at cell type specificity: AR divisions stop by 1.0 mm and the pace of somatic cell mitosis slows after 1.2 mm.
Scientists themselves often use the word "cloning" casually to refer to any use of somatic cell nuclear transfer.
