Notch Signal Activates Hypoxia Pathway through HES1-Dependent SRC/Signal Transducers and Activators of Transcription 3 Pathway

Abstract: We report a Notch signal-induced pathway that leads to transcriptional activation of HIF1-α gene. HeLa/rtTAA/ TRE-

“…57 On the other hand, the modulation of STAT3 phosphorylation is affected by Hes1 binding to STAT3 directly and then recruiting JAK and Src protein effectively. 58,59 Tumor dormancy appears to be the underlying mechanism for tumor resistance to chemotherapy. Hes1 correlates with dormancy, and this is mediated, in part, by retaining the tumor in a quiescent stage that can re-enter the cell cycle.…”

“…Of + reactive astrocytes found closest to the infarct core after stroke; these cells required Notch1 and ETB R for proliferation. Previously, Notch1 signaling was reported to stabilize p-STAT3 in both normal and transformed cells (24,36), and blockade of Notch1 signaling by GSI reduced stem-like glioblastoma cells and tumor growth in xenografts, prolonging host survival (37). Autocrine ETB R signaling is critical for selfrenewal and survival of glioblastoma stem cells (tumor-initiating cells) (38), and pharmacological antagonists of ETB R decreased proliferation and survival of glioma and oligodendroglioma cells (31,39).…”

“…O segundo processo libera o domínio intracelular do Notch (NICD), que é translocado da membrana para o núcleo e atua como coativador transcricional (Lahmar et al, 2008). O Notch ativo (NICD) interage com o fator transcricional ubiquitinoso (RBPJk/CSL) para regular positivamente a transcrição dos genes alvos, como HEY1 e HES1 (Figura 2) (Espinosa et al, 2002;Lehar & Bevan, 2002;Radtke et al, 2004;Lee et al, 2009;Magri et al, 2009). …”

“…A via de sinalização Notch apresenta relação com diversos processos como, por exemplo, o de diferenciação, proliferação e apoptose durante o desenvolvimento embrionário e, com a homeostase durante a vida pós-natal, principalmente na diferenciação de progenitores hematopoéticos e no desenvolvimento de células T (Artavanis- Tsakonas et al, 1999;Singh et al, 2000;Jaleco et al, 2001;Walker et al, 2001;Schmitt et al, 2002;Iso et al, 2003;Radtke et al, 2004;Wilson et al, 2006;Kutlesa et al, 2009;Lee et al, 2009;Magri et al, 2009).…”
