Expression of p53 , p21 and bcl-2 Proteins in Tongue Squamous Cell Carcinoma[J]. Journal of Sun Yat-sen University (Medical Sciences), 2000, 21(4).DOI:
p21 and bcl-2 proteins in tongue squamous cell carcinomas (SCC)and their sig nificances .【Methods】The ex pression of p53
p21 and bcl-2 proteins in 54 cases of tongue SCC w as detected by immunohistochemical SP method .【Results】The positive expression of p53
p21 and bcl-2 pro teins in to ngue SCC were 46 %
61 %
46 %
respect ively .The expression of p53 and p21 pro teins w ere related w ith tumor pathological g rade (P <0.05)and cervical lymph node metastasis.The expression of p21 protein w as associated wi th that of p53 pro tein (P <0.05).There w as no sig nificant relation amo ng the expression of the three proteins.【Conclusion】p53
p21 and bcl-2 pro teins can ex tensively posi tive express in tongue SCC .The expression of p53 and/or p21 proteins is valuable in determining the tumor biological behavior
