Collectively, our results indicate that sortilin may play a critical role in prostate cancer progression by reducing progranulin levels and progranulin-dependent migration, invasion, proliferation, and anchorage-independent growth of castration-resistant prostate cancer cells. This process, which is not detected in CDexpressing normal mesenchymal cells, is inhibited by disruption of the IGF-1R signaling, whereas enhanced by IGF-1 stimulation. Annu Rev Cell Dev Biol. We have previously demonstrated that the growth factor progranulin may play a significant role as an autocrine growth factor in prostate tumor progression by promoting proliferation, migration, and anchorage-independent growth of castration-resistant cells prostate cancer cells 6. Because we previously demonstrated that castration-resistant PC3 and DU prostate cancer cells secrete progranulin, which acts as autocrine growth factor and promotes motility, proliferation, and invasion of these cells 6we wanted to determine whether sortilin might play any role in regulating progranulin action in PC3 and DU cells. This difference is likely due to the higher level of sortilin expression in PC3 cells, which may more effectively counteract progranulin action in these cells. Kovar H.

|In the second patient studied, suffering from lung adenocarcinoma, all the cells had a large amplification Mbp on chromosome 8 up to over 10 copies harboring, among others, the c-MYC gene.
Briefly, cells were seeded into 6-well plates in serum-containing medium. Transforming mutations of RAC guanosine triphosphatases in human cancers. Statistical analysis Differences among means were analyzed by Student's t test.
First line of therapy for metastatic prostate cancer is androgen-deprivation therapy, but tumors often recur and progress to the castration-resistant stage with limited therapeutic options 36 — We then tested the ability of the various prostate cancer cells to invade a 3-dimensional extracellular matrix by performing invasion assays using Matrigel-coated transwells, as we previously described 67

The identification of novel mechanisms inducing cell death independently of canonical apoptosis is therefore imperative for developing new therapeutic approaches for EWS patients.
F, Migration was performed as described in Materials and Methods. S15 Fig. These results support the view that it is the progranulin internalized from the outside the one targeted by sortilin for lysosomal degradation and not endogenous progranulin along the secretory route.

|Collectively, these results indicate a critical role for sortilin in regulating progranulin action in castration-resistant cells, suggesting that sortilin loss may contribute to prostate cancer progression.
It is to note that, while longer bins may miss smaller CNAs, on average A dataset at 3, reads served as reference for ROC analysis. Arrows indicate empty vacuoles, void of cytoplasm and organelles. Overall, we propose CD99 targeting as new opportunity to treat EWS patients resistant to canonical apoptosis-inducing agents. Demetrius H. Email alerts New issue alert.
