Moreover, the particles could be efficiently internalized by FA-receptor-rich MCF-7 cells through the receptor-mediated endocytosis, whereas FA-receptor-poor HEK-293T normal cells showed much lower endocytosis of the nanoparticles under the same conditions.
Furthermore, proteinase-like peptidase activities were previously found to be higher in patients with steroid receptor-rich breast tumours than in receptor-poor tumours (Vasishta et al, 1989).
They were then incubated in a rabbit anti-μ opioid receptor antibody (1 1,000 in PBS-NGS 1 % at 4 °C overnight; Immunostar) followed by incubation in donkey anti-rabbit secondary antibody conjugated to Cy3 (1:400, Jackson) to determine the location of the neurons with respect to the patch/striosome (μ-opioid receptor-rich) and matrix (μ-opioid receptor-poor) compartments of the striatum.
In sporadic breast cancer, absent or reduced BRCA1 expression was associated with high tumor grade, advanced lymph node stage, larger size, vascular invasion, negative estrogen receptor, negative progesterone receptor and poor outcome[27].
Elevated MYO10 levels were correlated with oestrogen receptor status, progesterone receptor status, poor differentiation, and lymph node metastasis.
Several 1,3-dipropyl derivatives endowed with nanomolar binding affinity at hA2B receptors, but poor selectivity over hA2A, hA1 and hA3 AR subtypes were identified.
Breast cancer in young women is correlated with aggressive tumour progression, lack of expression of receptors and poor prognosis [ 18].
In comparison, the conventional antipsychotic haloperidol which displays a high antagonistic activity at dopamine D2 receptors is poor substrate of P-gp.
Information on the distribution, regulation and function of endogenous AM receptors is poor, and data on their role in human tumour biology is not available.
With the extensive polymorphism penetration in Toll-like receptors, a poor antibody response to influenza vaccination presents another confounding variable unaccounted for by simply relying on chronologic age.
