Malignant transformation of various cell lines by retrograde transforming viruses and other means leads to increased PBGD activity (Rasetti et al, 1963; Kondo et al, 1993).
The process of acclimation depends on transformation of retrograde signals in gene expression, transcript accumulation and de novo protein synthesis.
The proposed step by step process of transformation from retrograde menstruation to ovarian cancer is presented in Figure 2. Endometriosis is strongly correlated with a history of infertility and nulliparity [ 1].
Transformation - Transforms the user.
Historically a metaplastic transformation of peritoneal cells or the still favourably retrograde menstruation of cells through the tubes into the peritoneal cavity are discussed [ 29].
This is due, in part, to Sadat's great mistake -- believing that just one decision, making peace with Israel, would trigger a transformation of Arab society, rain money on the region and overwhelm the retrograde forces.
Intriguingly, another recent report suggests that NSCLCs harboring mutations both in KRAS and LKB1 are addicted to coatomer complex I (COPI -dependent lysosome aCOPI -dependenthich participates in retrograde transport, is required for endosome maturation and is a CDC42 effector required for CDC42 transformation.
This regulation point also reveals the existence of at least two different types of COPI-dependent Golgi-trafficetrograde trafficarriersrs: one type of transport, GalNAc-Ts, is activated by growth factor stimulation and cancerous transformation and is repressed by ERK8; the other, KDEL-R, is activated by cargo protein traffic and is independent of ERK8.
This idea, also known as the retrograde hypothesis, has intuitive appeal and states that if the contemporary biosynthesis of compound "A" requires the sequential transformation of precursors "D," "C," and "B" through the corresponding enzymes, the final product "A" of a given metabolic route was the first compound used by the primordial heterotrophs (Fig. 8).
