FOXO3a knockdown promoted the migration and invasion of PDAC cells. a Wound healing assay was carried out to investigate the migratory ability of PANC-1 and SW1990 cells. b Transwell migration and invasion assays were applied to assess the migratory and invasive capacities of PANC-1 and SW1990 cells. *P < 0.05, **P < 0.01, ***P < 0.001
Fig. 4
SPRY2 silencing promoted the migration and invasion of PDAC cells (a) Wound healing assay was carried out to investigate the migratory ability of PANC-1 and SW1990 cells. b Transwell assay was applied to assess the migratory and invasive capacities of PANC-1 and SW1990 cells. *P < 0.05, **P < 0.01, ***P < 0.001

Silencing of β-catenin reversed the promotion effects of FOXO3a knockdown on EMT- associated migration and invasion of PDAC cells. a Wound healing assay was carried out to investigate the migratory ability of PANC-1 and SW1990 cells. b Transwell assay was applied to assess the migratory and invasive capacities of PANC-1 and SW1990 cells. c The protein expression of FOXO3a, SPRY2, β-catenin, TCF4, E-cad and VIM were detected in PANC-1 and SW1990 cells by Western blot. *P < 0.05, **P < 0.01, ***P < 0.001, ns non-significant
Fig. 8
SPRY2 silencing reversed the suppressor effects induced by FOXO3a overexpression on EMT-associated migration and invasion of PDAC cells. a Wound healing assay was carried out to investigate the migratory ability of PANC-1 and SW1990 cells. b Transwell assay was applied to assess the migratory and invasive capacities of PANC-1 and SW1990 cells. c The protein expression of FOXO3a, SPRY2, β-catenin, TCF4, E-cad and VIM were detected in PANC-1 and SW1990 cells by Western blot. *P < 0.05, **P < 0.01, ***P < 0.001, ns non-significant

Gerade bei aggressiven Malignomen wie dem duktalen Adenokarzinom des Pankreas könnte Früherkennung die Therapiechancen verbessern. Noch jedoch klafft hier eine Lücke. Ein Studienteam hat einen Weg gesucht, sie zu schließen.
Ein hoher Anteil pflanzlicher Nahrung trägt möglicherweise dazu bei, das Progressionsrisiko von Männern mit Prostatakarzinomen zu senken. In einer US-Studie war das Risiko bei ausgeprägter pflanzlicher Ernährung in etwa halbiert.
Ein höheres Alter bei der Diagnose eines Endometriumkarzinoms ist mit aggressiveren Tumorcharakteristika assoziiert, scheint aber auch unabhängig von bekannten Risikofaktoren die Prognose der Erkrankung zu verschlimmern.
In einer Leseranfrage in der Zeitschrift Journal of the American Academy of Dermatology möchte ein anonymer Dermatologe bzw. eine anonyme Dermatologin wissen, ob er oder sie einen Patienten behandeln muss, der eine rassistische Tätowierung trägt.
