In cases where an infiltrate was present, a similar pattern was observed and the more malignant tissues exhibited a higher degree of immune cell infiltration.
This flatter spectral slope for the more ordered malignant tissue (exemplified by highly periodic helical fibrils compared to the more randomly appearing normal tissue) is predicted by the recent theoretical treatment by Backman [ 42].
CYP2E1 was expressed in both normal and tumour tissues, although expression was more intense in malignant tissue.
Cancer stem-like cells (CSCs) are a more malignant composition in tumor tissues inhibiting immune response.
(a) The capillary endothelium system in malignant tissue shows more permeation to macromolecules in comparison to normal tissue endothelium; this makes circulating polymeric nanoparticles permeable into the tumor.
In seven of 15 breast cancer patients, let-7a expression was more downregulated in malignant tissues than in normal counterpart tissues.
Previous studies have consistently suggested that TfR is expressed more abundantly in malignant tissues than that in their healthy counterparts [ 3- 8].
Using a space filling analysis of TEM images we found that the packing of the fibrils in the malignant tissue to be more regular relative to the normal (10% vs 15% inter-fibrillar space respectively).
This data agrees with previous smaller studies showing increased NIS expression in malignant tissue [3], [4], and also more surprisingly in fibroadenoma compared to malignant tissue [3].
