Nox·a

(nokz'ah),
[MIM*604959] a critical mediator protein involved in apoptosis induced by tumor suppressor p53 and other agents in cells that are exposed to noxious stresses. The protein is encoded by the gene Noxa (for damage).

nox·a

(nok'să),
Anything that exerts a harmful influence (for example, trauma, poison).
[L. injury, fr. noceo, to injure]

noxa

(nŏk′să) plural.noxae [L., injury]
Anything harmful to health.

It will be interesting to know whether Grail can cooperate with pro-apoptotic proteins (bax, puma, or noxa) in p53-induced cell death in KB cells.
This contradicts old ideas that considered pregnancy as a period which protects both the woman and the fetus from any noxa (5)
In TGCT, apoptosis is induced by proapoptotic proteins such as Noxa and Puma because of the low mutation rates of tumor suppressors such as p53 and Rb.
jirovecii no solo estaba asociada con el deterioro de la funcion pulmonar, sino de manera paralela con el aumento de la respuesta inflamatoria tipo Th2, al hallarse un aumento en las concentraciones de interleucinas 4, 5, 6 y factor estimulador de colonias granulociticas en los lavados broncoalveolares de los primates colonizados versus los no colonizados, asi como un aumento en el tejido linfoide asociado a bronquios (47); sin embargo, no se evidencio progresion del deterioro pulmonar, lo que sugiere la necesidad de una noxa adicional para disminuir la funcion pulmonar en humanos (48).
Oncogenic Ras-induced expression of Noxa and Beclin-1 promotes autophagic cell death and limits clonogenic survival.
The methylation-mediated gene silencing of PRDM14, a regulator of NOXA and PUMA-mediated apoptosis, becomes an important factor in the development of hr-HPV-ICC (invasive cervical carcinoma) and offers a novel therapeutic target for HPV-induced cervical cancers [65].
Interestingly, NANOG upregulates histone deacetylases 1 (HDAC1) via binding to the promoter region and decreasing K14 and K27 histone H3 acetylation; as a result, it induces not only the stem-like features through epigenetic repression of cell cycle inhibitor CDKN2D and CDKN1B but also the immune resistance and chemoresistance through MCL-1 upregulation by epigenetic silencing of E3 ubiquitin-ligase TRIM17 and NOXA [148].
Despite the potential effects of the concomitant immunosuppressive therapy, pancreas transplantation represents an optimal model to study the effects of reestablishment of stable normoglycemia in advanced diabetic neuropathy and provides an opportunity to examine whether correction of the principal metabolic noxa, hyperglycemia, may lead to any functional and morphological improvement.
In p53-induced apoptosis, mRNA increases for BID [40]; p53 also induces p53 upregulated modulator of apoptosis (PUMA) and NOXA expression, followed by the release of BAX and BAK from their complexes with antiapoptotic proteins and consequently mitochondrial outer membrane channel formation (Figure 2) [41-44].
Sporadic genetic mutation and maternal exposure to toxic or infectious Noxa were considered to be more likely etiology.
