背景介绍
Squamous cell carcinoma antigens 1 and 2 (SCCA1 and 2, SERPIN B3 and B4) are members of the ovalbumin family of serine proteinase inhibitors. SCCA1 and SCCA2 are highly homologous proteins, 91% identical at the amino acid level, and probably evolving from a common ancestor gene. The neutral form of SCCA (SCCA1, or SERPINB3) is detected in the cytoplasm of normal and some malignant squamous cells, whereas the acidic form (SCCA2, or SERPINB4) is expressed primarily in malignant cells and is the major form found in the plasma of cancer patients. SCCA2 (SERPINB4), along with SCCA1(SERPINB3), can be processed into smaller fragments that aggregate to form an autoantigen in psoriasis, probably by causing chronic inflammation. This antibody can recognize both SerpinB3 and SerpinB4.

同时，Apaf―1可以激活原形的caspase―9，形成细胞色素C／Apaf―1／caspase―9复合体，即凋亡复合体(apoptosome)。该复合体水解并激活下游的caspase通路如caspase―3等。 凋亡复合体的形成是凋亡信号启动的关键步骤。目前发现激活的癌基因可以辅助凋亡复合体的形成，比如腺病毒EIA可以上调Apaf―1和caspase―9，E2F1可以上调Apaf―1的表达。Apaf―1的释放可促进凋亡复合体的形成，对凋亡的启动起促进作用。目前的研究认为，细胞
