It can be used to describe a phrase or statement that conveys an optimistic or affirmative sentiment.
Example: "Her words were a positive expression of support during a difficult time."
Alternatives: "an uplifting statement" or "a favorable remark".
We next classified patients into the following four subgroups according to the p-mTOR expression of their tumours and analysed survival: patients with positive expressions of both cytoplasmic and nuclear p-mTOR (group A), positive expression of only cytoplasmic p-mTOR (B), positive expression of only nuclear p-mTOR (C), and negative expressions of both cytoplasmic and nuclear p-mTOR (D).
Interestingly, we found a positive expression correlation for highly expressed retrocopies and their neighboring coding genes for retrocopies located downstream of the coding genes regardless their expected transcriptional orientation, in the same or in the opposite DNA strand (supplementary table S6, Supplementary Material online; ρ = 0.97; P value < 2.2e-16; Spearman's correlations).
Thus any protein remaining with a positive expression value is considered to be significantly expressed [ 76].
These cell lines all showed a positive expression of MEPE/OF45, although the levels of expression varied, indicating that MEPE/OF45 expresses in replicating cells.
Furthermore, when expressing negative concepts, people are inclined to use the negation of a positive expression to alleviate sentiments, instead of using negative expressions directly.
It would be of interest to observe if the rare acinar cell pancreatic carcinoma (non-ductal epithelium derived cancer) expresses M2-PK and if true, this is likely to be a positive expression marker for acinar-cell derived tumours.
Aurora-A expression on tumor cells was first classified into negative or positive expression; a slide was judged to be Aurora-A positive expression, regardless of the staining intensity.
Four had a stable positive expression of MT3 over all samples, and only one patient had a stronger expression of MT3 at recurrence compared to diagnosis.
Under hypoxia a surprising positive expression of SMCs markers was observed [Figure 2J, 2N and 2R (for type I collagen), 2L, 2P and 2T (for PEMs)].
In this cohort, we found a differential positive expression of HDAC1, HDAC2 and HDAC3.
HCC with earlier TNM stages is found to have a higher positive expression rate of the livin protein [ 13].
