Retinoic acid receptor (RAR ) gene rearrangement by reciprocal chromosome translocation is the molecular signature of acute promyelocytic leukemia (APL). Disruption of RAR function appears to be the likely cause of aberrant myelopoiesis observed in APL, because PML-RAR expression has been shown to deregulate the transcription of genes that control myelopoiesis. To target RAR chimeric proteins, ...

The discovery that transcription factors are frequently disrupted in leukemia has led to efforts to target these proteins with drugs. These efforts have met with limited success, partly because it has proved difficult to design and deliver into the nucleus small molecules that might break up interactions between transcription factors and their target genes or cofactors. Hence the belief that tr...

Abstract Background Nano-fibrous scaffolds provide a three-dimensional matrix that guides sufficient orientation of seeded cells similar to natural niche. In this research, we designed silk scaffold improve the differention mouse spermatogonial stem spermatogenic cell lines. Spermatogonial were collected from neonatal (2–6 days) testes ( n =60) using two steps mechanical and enzymatic method. C...

Many studies suggest that far-infrared (FIR) therapy can reduce the frequency of some vascular-related diseases. The non-thermal effect of FIR was recently found to play a role in the long-term protective effect on vascular function, but its molecular mechanism is still unknown. In the present study, we evaluated the biological effect of FIR on vascular endothelial growth factor (VEGF)-induced ...

RETINOIDS AND IN particular retinoic acid are naturally occurring compounds that regulate the growth and differentiation of a variety of different cell types. The observation that retinoic acid induces the terminal differentiation of human acute promyelocytic leukemia (APL) cells both in vitro1 and in vivo2-4 has had a significant impact in clinical hematology and has altered our approach to th...
