Biological or genetic differences resulting from mutations in the PI3K pathway could account for the activated Akt tumors, in addition to mutations or loss of PTEN (phosphatase and tensin homolog deleted on chromosome 10) in HER2/neu-overexpressing breast tumors.
The experience of pain is subject to individual differences resulting from psychological factors, behavioral factors and biological factors [1] [4].
Biological differences in a typical experiment are much greater than differences resulting from technical manipulations in labeling and hybridization.

Prevention and Treatment, 5, Article 23. (Retrieved July 19 , 2007from http://journals.apa.org/prevention/volume5)], have shown a modest drug-placebo difference but methodological problems with standard trial design preclude a definitive conclusion that this difference results from specific biological effects of antidepressants or the nonspecific factors that have not been adequately excluded.
Additionally, since different morphs within the same clonal line are genetically identical, their morphological, biological and ecological differences must result from differences in gene expression [e.g. [ 12]], which may be facilitated by duplicate, divergent chromatin remodeling genes [ 6].
We infer that the differences resulted mainly from biological variations among the three animals in each experimental group rather than from measurement error (cf. Figure 7).
She said those differences might result from differences in educational opportunities, upbringing or other factors.
Accordingly, research is needed to assess if the varying relationship between alcohol consumption and ischemic heart disease in different age groups results from biological differences in pathology or from differences in drinking patterns.
