Each PET specimen and non-tumourous pancreatic specimens were evaluated independently by the authors and graded as low, high or heterogeneous (i.e. areas of both low and high expression present in the tumour).
Given the high copy number and varying levels of intragenomic heterogeneity of the ITS2[ 15] 15], Next-Generation Sequencing (NGS) was used to obtain sequences of ITS2 from each specimen and non-metric multidimensional scaling (nMDS) was used to analyze intragenomic, intraspecific, and interspecific sequence clustering.
Frozen human lung tumor specimens and non malignant tissues were obtained from Cooperative Human Tissue Network, Vanderbilt University Medical Center (Nashville, TN).
GPR antenna of 1.0 GHz and 2.3 GHz central frequency scans respectively the inner-cracked specimens and non-crack one.
Unselected formalin-fixed breast cancer specimens and non-cancer specimens from women who had breast reduction surgery, were analysed using in situ PCR.
MicroRNA profiles were analyzed in three pairs of CCA tumor specimens and non-tumorous-paired biliary tissues using Agilent microRNA microarrays.
After one to two weeks of culture the tissue specimens and non-adherent cells were discarded and cells were trypsinized with Trypsin-EDTA (Gibco, Scotland, UK) and subcultured by trypsination three to four weeks after initial explantation (at 80% confluence).
Similar analysis of the differentially expressed genes between BPH specimens and non-cancerous parts of the glands-exhibiting malignant pathology also showed moderate to high discriminative properties, with AUCs ranging between 0.671 and 0.943.
Quantitative real-time polymerase chain reaction was used to validate and detect the expression of LNβ3 mRNA in 37 pancreatic carcinoma tissue specimens and non-neoplastic pancreatic tissue samples.
Interestingly, vitamin D transcriptional effects may not overlap in tumor specimens and non-transformed mammary glands in the MMTV-neu transgenic mouse model of breast cancer, fed a high vitamin D diet [ 51].
Since not all subjects donated specimens for cadmium determination, it is possible that differences in cadmium burden exist between specimen donors and non-donors.
