5 CLUES Personal Profile - Well structured CV MOTIVATION LETTER!!! The training program The research project

6 Translational Research Program Molecular characterisation of the stromal microenvironment in pancreatic adenocarcinoma and its role in tumour progression and prognosis Caveolin and SHH Interaction in pancreatic cancer

7 Caveolae and Caveolins Caveolin-1 From B Alberts Molecular Biology of the cell CAVEOLAE

8 Central role of Hedgehog signaling in biology DEVELOPMENT HOMEOSTASIS Organizing centers Patterning Proliferation Angiogenesis Survival Sonic (Shh) Indian (Ihh) Desert (Dhh) Repair/regeneration Angiogenesis Proliferation Survival CANCER Angiogenesis Proliferation Survival Stroma

9 Hh HEDGEHOG SIGNALING On SMOOTHENED PATCHED CDO/BOC Sufu PKA Gli GSK3 P CK-1 G Gli P Gli-R GBS Target genes: Gli1, Ptc1

10 Breast Cancer Fibrosis caused by lack of caveolin and associated with poor prognosis CAF without caveolin Induce cancer cells to EMT Feed cancer cells through nutrients secretion

11 Pancreatic Cancer Pancreatic ductal adenocarcinoma (PDA) Among the most lethal human cancers Highly heterogeneous Insensitive to many chemotherapeutic drugs

12 PDA? Br J Cancer Nov 4;87(10): Impact of caveolin-1 expression on prognosis of pancreatic ductal adenocarcinoma tumour diameter (P=0.0079) histopathologic grade (P=0.0272) poor prognosis (P=0.0008). + CAV-1 expression was shown to be an independent negative predictor for survival (P=0.0358)

13 Hedgehog is an early and late mediator of pancreatic cancer tumorigenesis a. Immunohistochemical identification of SHH. a, Normal human pancreas. No specific staining for SHH protein was identified in acini, islets (I) or ducts (D) (X125 magnification). No SHH expression is detected in normal ductal epithelium (x500 magnification). Thayer SP, Nature. 2003

14 Science 2009 June (5993) Inhibition of Hedgehog Signaling Enhances Delivery of Chemotherapy in a mouse model of Pancreatic Cancer

23 Different tumors Different cell lines Chemosensitivity In vivo Analysis Coculture

24 Lessons I have learned Many Lab Techniques Primary tissue culture techniques quantitative Real Time PCR to Extract whole cell protein-western Blot Cloning of expression vectors to induce transient overexpression of target molecules (i.e. Gli2 and PTCH1) Plasmid Transfection Infecting primary cell lines with lentivirus expressing short hairpin RNA for stable silencing of target genes ( i.e. caveolin 1) Fibroblast Isolation Shorting cells Confocal Imaging-Immunofluorescence.

25 Lessons I have learned Understand MATERIALS and METHODS Lab work matured my clinical thinking Lab world is different from Clinical world Exciting -Enthusiasm Disappointment Be patient There is no time in the lab Have to Ask for help and collaborate Have to repeat Have to be consistent More questions than answers A good translational paper needs a lot of effort (years?)

26 Not only. Participate in Phase I and Gastrointestinal clinics

27 Networking

28 Suggestions BE MOTIVATED SEARCH-STUDY APPLY AND RE-APPLY BE PATIENT AND PERSISTENT BE OPTIMISTIC WORK HARD FORM PARTICIPATE in NETWORKS IMPLEMENT what you have learned
