    Lymphatic vessels are important for tissue fluid homeostasis, lipid absorption, and immune cell trafficking and are involved in the pathogenesis of several human diseases. The mechanisms by which the lymphatic vasculature network is formed, remodeled, and adapted to physiological and pathological challenges are controlled by an intricate balance of growth factor and biomechanical cues. These transduce signals for the readjustment of gene expression and lymphatic endothelial migration, proliferation, and differentiation. In this review, we describe several of these cues and how they are integrated for the generation of functional lymphatic vessel networks.

    Background: Patients with castration-resistant prostate cancer (CRPC) had extended responses to the androgen receptor antagonist ODM-201, in phase 1/2 studies. Objective: To evaluate the safety and antitumour activity of prolonged ODM-201 treatment in patients with CRPC. Design, setting, and participants: The ARADES trial was a multicentre phase 1 (dose escalation) and phase 2 (dose expansion) trial; 134 patients with CRPC were stratified by previous chemotherapy to receive ODM-201. This paper reports extended follow-up in CYP17 inhibitor (CYP17i)-naïve patients. Intervention: Patients (n = 77) received oral ODM-201 twice daily at daily doses of 200–1800 mg. Outcome measurements and statistical analysis: Safety, measured as the occurrence of adverse events (AEs), prostate-specific antigen (PSA), and radiographic progression. Results and limitations: The safety profile of extended ODM-201 treatment (median treatment duration 8.2 mo, 95% confidence interval [CI] 5.6–11.0) was consistent with that reported at the time of the original data cutoff in the main ARADES trial, with no unexpected safety concerns over time. The majority of AEs (61.1%) were mild (grade 1); the most common AE was fatigue/asthenia (35.1% of patients), with no clear relationship to ODM-201. Median time to PSA progression was 25.2 mo (95% CI 11.3–25.2) for chemotherapy-naïve men and not reached (NR; 95% CI 5.5–NR) for chemotherapy-pretreated patients; a trend for improved antitumour response was observed for chemotherapy-naïve patients. The median time to radiographic progression was longer for chemotherapy-naïve (14.0 mo, 95% CI 8.1–33.3) than for chemotherapy-pretreated (7.2 mo, 95% CI 2.7–11.0) patients. Conclusions: Prolonged exposure to ODM-201 was well tolerated, with no additional safety concerns; disease suppression was sustained, especially in chemotherapy-naïve patients. These data support further development of ODM-201 in men with CYP17i-naïve CRPC. Patient summary: Extended ODM-201 therapy was well tolerated, with beneficial antitumour activity in men with advanced prostate cancer, indicating that ODM-201 may represent a new active treatment for men with CRPC. This extension trial is registered at ( under identification number NCT01429064. Extended ODM-201 therapy showed encouraging antitumour activity in both chemotherapy-naïve and chemotherapy-treated men with metastatic castration-resistant prostate cancer (CRPC). Continued treatment with ODM-201 was well tolerated, with no unexpected safety concerns, and may represent a new, effective treatment option for men with CRPC. © 2017 European Association of Urology

    Selvitin tutkimuksessani VEGF-C:n ja RET:n vaikutusta hiiren enterisen hermoston ja imusuoniston kehitykseen. Yhden ja kahden VEGF-C-alleelin puutos johti neuronien määrän vähenemiseen jejunumissa ja koolonissa. RET-alleelien puutos vähensi myös neuronien määrää ja kahden puutos esti neuronien kehittymisen. VEGF-C ja etenkin RET-muuntogeenisiä alkioita oli myös hiiripoikueissa vähemmän kuin Mendelistisen jakauman perusteella voisi olettaa. Tämä viittaa lisääntyneeseen kuolleisuuteen in utero. Myös ihon karvatuppia oli RET-homogeenisissä vähemmän kuin villityyppisissä. Lisäksi selvitin mitkä vasta-aineet soveltuvat käytettäväksi suolten erityyppisissä vastaainevärjäyksissä
