Proximal tubule epithelial cell line HK-2 with shRNA-mediated stable knock-down of HIF-1a and HIF-2a (Hypoxia-inducible factor 1-alpha and Hypoxia-inducible factor 2-alpha) 24 hours after treatment with hypoxia (20% O2). HK-2 cells were cultured in DMEM/F-12 supplemented with 10% fetal calf serum (FCS), 1% ITS, hydrocortisone, and antibiotics. The cells were incubated at 37 °C.

bronchial epithelial cell differentiation study 1 (day28) / bronchial epithelial cell differentiation study 1 (subconfluent)

Relative Expression (log2-ratio):4.27341
Number of Samples:3 / 3
Experimental bronchial epithelial cell differentiation study 1 (day28)
Differentiated normal human bronchial epithelial cell (NHBE) cultured for 28 days in an air-liquid interface (ALI) system. At this time point cells were fully differentiated and formed a polarized, pseudostratified mucociliary epithelium. In order to generate the ALI culture, undifferentiated cells were grown under submerged conditions in bronchial air-liquid interface (B-ALI) growth basal medium supplemented with expansion media. When cells reached confluency (after 3-5 days), an air-liquid interface culture (ALI system) was created by removing the apical medium and replacing the medium of the basal compartment with B-ALI differentiation medium. During the 28 days culture medium was replaced every 48 hour.
Control bronchial epithelial cell differentiation study 1 (subconfluent)
Subconfluent undifferentiated normal human bronchial epithelial cell (NHBE) cultured for 1-2 days under submerged conditions in bronchial air-liquid interface (B-ALI) growth basal medium supplemented with expansion media. At this time point cells still grew dispersed in the culture insert and covered 70% of the insert.

rectal cancer study 2 (post; chemoradiotherapy) / rectal cancer study 2 (post; no therapy)

Relative Expression (log2-ratio):4.089981
Number of Samples:4 / 2
Experimental rectal cancer study 2 (post; chemoradiotherapy)
Tumor tissue samples obtained from the rectum of patients with rectal adenocarcinoma during a surgical resection, after a treatment with neoadjuvant concurrent (5-FU-based) chemoradiotherapy (CRT). The regimen of the neoadjuvant CRT was as follows: folinic acid 20mg/m2, 5-flurouracil (5-FU), 350mg/m2 d1-5, and d29-33 with 45 Gy in 25 fractions. Samples were collected after 6-8 weeks of completing the therapy. Patients were selected for neoadjuvant CRT based upon clinical and MRI staging features. Radiotherapy was CT planned, using a 3 field technique (posterior and two lateral fields), multileaf collimation and with patients having a full bladder during the radiotherapy. Patients were proven to be medically fit for treatment (WHO PS 0-2), with no significant medical co-morbidities, in particular no history of unstable or severe ischemic heart disease, and adequate renal (creatinine clearance >50ml/min) and liver function (billirubin <1.5 ULN, transaminases and alkaline phosphatase <2x ULN ). The staging was performed by clinical examination high resolution MRI of the pelvis (under anaesthesia at the discretion of the treating surgeon), and CT scan of the thorax and abdomen. Tumor stage was assigned according to TMN classification of UICC 6th edition 2002.
Control rectal cancer study 2 (post; no therapy)
