What does the p63 gene do?
Normal Function. The TP63 gene provides instructions for making a protein called tumor protein p63 (also known simply as p63). The p63 protein functions as a transcription factor, which means it attaches (binds) to certain regions of DNA and controls the activity of particular genes.
Is p63 a tumor suppressor?
p63 Expression in Cancer Mutations of p63 are extremely rare in human cancers, indicating it is not a canonical tumor suppressor.
What does positive for p63 mean?
P63: scored positive when high intensity staining was present on ≥50% of tumor cells; the remainder was scored negative [10]. TTF-1: scored positive when staining was present on ≥5% of tumor cells; the remainder was scored negative [11].
What does p63 positive mean?
What is p63 in breast biopsy?
Abstract. p63, a member of the p53 gene family, is involved in cellular differentiation and is expressed in the nuclei of myoepithelial cells of normal breast ducts and lobules.
What is p63 negative mean?
p63 is negative in malignant tumors of the prostate. Striated muscle staining may be observed with p63. Interpretation. This test does not include pathologist interpretation, only technical performance of the stain.
What does p63 positive mean in breast?
P63 is a positive prognostic factor in endocrine-treated ER positive breast cancer and might influence responsiveness to endocrine treatment. Thus, p63 could be helpful as a predictive factor for endocrine therapy.
What is the difference between the P-39 and P-63?
Based on the preceding Bell P-39 Airacobra, the P-63’s design incorporated suggestions from P-39 pilots and was superior to its predecessor in virtually all respects. The P-63 was not accepted for combat use by the United States Army Air Forces.
What is a P-63 Kingcobra?
The Bell P-63 Kingcobra is an American fighter aircraft that was developed by Bell Aircraft during World War II. Based on the preceding Bell P-39 Airacobra, the P-63’s design incorporated suggestions from P-39 pilots and was superior to its predecessor in virtually all respects.
What was the p-63c modified for the Navy?
Two war surplus P-63Cs were modified by Bell under Navy contract for flight testing of low-speed and stall characteristics of high-speed wing designs. The aircraft received new wings with adjustable leading edge slats, trailing edge flaps and a pronounced sweep of 35 degrees.
Was the P-39/P-63 a ground-attack aircraft?
One of the enduring myths regarding the P-39/P-63 in Soviet use is that because of its armament, in particular the 37mm nose cannon, it excelled as a ground-attack aircraft, even a ‘tank buster’. In translating and preparing this manuscript for publication, I have had the opportunity to peruse several Russian-language sources.
