Then, according to our results, sFas continued to rise with the increase of the aggressiveness of bladder cancer, and it may be used as an indicator of the malignant degree of bladder cancer.
> According to the previous studies of histological differentiation and malignant degree of gastric carcinoma, non-mucinous adenocarcinoma (papillary adenocarcinoma and high, medium and low differentiated tubular adenocarcinoma) were assigned as 1 3 points, respectively.
The level of VEGF is closely associated with microvessel density and the malignant degree of tumors and is increasing in tumor tissues compared with non-tumor tissues [ 47], suggesting that VEGF may promote tumorigenesis by regulating LRP1 to enhance angiogenesis.
Therefore, it has a positive correlation between the expression levels of miR-26a and the malignant degree of CRC cells.As miRNA expression is often inversely correlated with those of their specific target mRNAs, we further analyzed the protein expression of the miR-26a target —PDHX, in CRC cell lines.
In our study, the AP-2γ-ChIP fragments were obtained from human breast cancer cell line MDA-MB-453 with high malignant degree; knock-down of AP-2γ expression in MDA-MB-453 cells by siRNA decreased the expressions of ErbB2, CDH2, IGSF11 and HPSE, but overexpression of AP-2γ in MDA-MB-231 cells elevated their mRNA and protein levels.
Ki-67 labeling index of ovarian adenocarcinoma indicates significantly higher malignancy than low malignant degree ovarian carcinoma [ 80].
However, these features are not always present; thus, they are less applicable in the discrimination of malignant degree.
Cell proliferation degree consists with tumor malignant degree.
The reason might be linked to tumor malignant degree [ 65].
However, the varying degrees of malignant B-cell frequencies in analysed samples influence the interpretation of the GEPs.
