Survivin, also called baculoviral inhibitor of apoptosis repeat-containing 5 or BIRC5, is a protein that, in humans, is encoded by the BIRC5 gene. Survivin is a member of the inhibitor of apoptosis (IAP) family. The survivin protein functions to inhibit caspase activation, thereby leading to negative regulation of apoptosis or programmed cell death. This has been shown by disruption of survivin induction pathways leading to increase in apoptosis and decrease in tumour growth. The survivin protein is expressed highly in most human tumours and fetal tissue, but is completely absent in terminally differentiated cells. These data suggest survivin might provide a new target for cancer therapy that would discriminate between transformed and normal cells. Survivin expression is also highly regulated by the cell cycle and is only expressed in the G2-M phase. It is known that Survivin localizes to the mitotic spindle by interaction with tubulin during mitosis and may play a contributing role in regulating mitosis. The molecular mechanisms of survivin regulation are still not well understood, but regulation of survivin seems to be linked to the p53 protein. It also is a direct target gene of the Wnt pathway and is upregulated by beta-catenin.
A protein chip for early warning of liver cancer and application thereof
This invention provides a protein chip for early warning of liver cancer and its application. The protein chip includes an antigen set; the antigen set includes antigens; the antibodies corresponding to the antigens are at least one of 61 selected from GNA11, GNAS, IDH1, MSH2, NPM1, PAX5, PTCH1, PTEN, SRSF2, Survivin, CAST, PAIP1, PRKCZ, RAD23A, RUNX1T1, SARS, TP53, APEX2, RCSD1, and AIF1; the protein chip is used for early warning assessment of liver cancer, and the early warning assessment steps include: collecting serum from the target population, using the protein chip to detect the serum to obtain detection data, and then determining whether they belong to a low-risk, medium-risk, or high-risk population based on a risk warning model; the protein chip systematically detects tumor-related autoantibody risk factor signals using high-throughput technology for early warning detection of liver cancer.

A method for preparing a multifunctional nanocomposite delivery system CEL-TPP@siSurvivin / TDNP NPs and its application in breast cancer therapeutics.
This invention discloses a method for preparing a multifunctional nanocomposite delivery system CEL-TPP@siSurvivin / TDNP NPs and its application in breast cancer treatment. The system is constructed by bridging triphenylphosphine-modified CEL with carboxyl-modified TPP, followed by electrostatic self-assembly of the product with negatively charged siSurvivin to form a nanocore, which is then encapsulated in turmeric-derived exosomes. This delivery system exhibits uniform spherical shape, a smooth surface, and good serum stability and cellular uptake capacity. TPP modification enables it to specifically target mitochondria, disrupt membrane potential, and synergistically knock down the survivin gene with siRNA, significantly promoting tumor cell apoptosis. This multifunctional nanocomposite delivery system overcomes the problem of poor water solubility of CEL and protects siRNA from nuclease degradation, achieving a highly efficient and synergistic anti-tumor effect.
