AnnexinA2 (ANXA2), a member of the Annexin family of calcium-dependent, phospholipid binding proteins, is one of a panel of identified antigens recognized by the post-vaccination sera of patients who demonstrated prolonged disease-free survival following multiple vaccinations. AnnexinA2 is abundantly expressed in pancreatic adenocarcinomas and cell surface/membrane AnnexinA2 increases with the progression from premalignant lesions to invasive pancreatic adenocarcinomas. The cytoplasmic to cell surface translocation of AnnexinA2 expression is critical for pancreatic cancer cell invasion. In addition, phosphorylation of AnnexinA2 at Tyrosine 23 is important for its localization to the cell surface and for the invasion of pancreatic cancer cells. Finally, loss of AnnexinA2 leads to the loss of the Epithelial-Mesenchymal Transition.

The invention discloses an application of a 4-LncRNA molecular tag in prognosis evaluation of liver cancer. The 4-LncRNA molecular tag is used for evaluating the total survival time and the disease-free survival time of a liver cancer patient, which finds that the total survival time and the disease-free survival time of patients in a high-risk group are notably shortened as compared with patientsin a low-risk group. Besides, the prognosis evaluation value of a clinical staging system of the liver cancer can be improved by means of the 4-LncRNA molecular tag, that is, evaluation and predication of patients of the same clinical stage find that the survival time of the patients in the high-risk group is notably different from that of the patients in the low-risk group. Therefore, the 4-LncRNA molecular tag can serve as a detection marker for prognosis evaluation of liver cancer, can provide prognosis effect evaluation as well as observation and monitoring for the patients, can be used for judging the prognosis situation of the patients and has the advantages of rapidness, objectiveness, accuracy and the like.

Cancers are phenotyped by analysis of the presence of immune cells, particularly T cells and dendritic cells, present in regional lymph nodes. When non-sentinel regional lymph nodes of a cancer patient are compared to normal lymph nodes, it is found that increased number of dendritic cells and decreased numbers of T cells, particularly T helper cells, correlate with a positive prognosis and disease-free survival following conventional chemotherapy.

The invention discloses application of gene HES2 to the auxiliary diagnosis, prognosis and treatment of esophageal squamous carcinoma. The HES2 gene is highly expressed in esophageal squamous carcinoma tissues. The experiment further discovers that mRNA of HES2 gene is highly expressed in an esophageal squamous carcinoma cell line, the progress of the HES2 high-expressed tumor is faster and is more likely to be transferred to lymph gland or far organs, which is significantly related to poor five-year disease-free survival rate and five-year general survival rate. In addition, an antisense oligonucleotide chain sequence targeting HES2 gene is also designed to silencing HES2 expression and can be useor the trd featment of esophageal cancer. HES2 can be used as a detection marker for assisting the diagnosis of the esophageal squamous carcinoma and predicting the reoccurrence trend of the esophageal squamous carcinoma as well as a treatment target spot.

The invention relates to the biotechnical field, and concretely relates to an application of 5-hydroxymethylcytosine and 5-formylcytosine in the preparation of a reagent or a kit for prognosis evaluation of hepatocellular carcinoma. It is found that the total genome 5hmC content and the genome 5fC content of HCC tissues are lower than those of cancer-adjacent tissues. Patients with reduced 5hmC and 5fC levels in HCC genome DNA have poor prognosis, and are prone to suffer from recurrence and metastasis.
