Abstract In this paper, we analyze the behaviour of solution for the system exemplifying model of tumour invasion and metastasis by the help of q-homotopy analysis transform method (q-HATM) with the fractional operator. The analyzed model consists of a system of three nonlinear differential equations elucidating the activation and the migratory response of the degradation of the matrix, tumour cells and production of degradative enzymes by the tumour cells. The considered method is graceful amalgamations of q-homotopy analysis technique with Laplace transform (LT), and Caputo–Fabrizio (CF) fractional operator is hired in the present study. By using the More >

Abstract ABCB5 belongs to the ATP-binding cassette (ABC) superfamily, which is recognized for playing a role in the failure of chemotherapy. ABCB5 has also been found to be overexpressed at the transcriptional level in a number of cancer subtypes, including breast cancer. However, the exact mechanism ABCB5 uses on cancer cell metastasis is still unclear. In the present study, we demonstrate that ABCB5 expression was increased in metastatic tissues when compared with nonmetastatic tissues. ABCB5 can significantly enhance metastasis and epithelial–mesenchymal transition (EMT), while knockdown of ABCB5 inhibited these processes. Microarray analysis indicated that ZEB1 may More >

Abstract Cullin7 is an E3 ubiquitin ligase. The Cullin7 protein family functions as a molecular scaffold to coordinate substrate ubiquitination in Skp, Cullin, and F-box-containing complex (SCF complex). Cullin7s control normal development and primary cellular processes and are characterized by a unique genomic network organization. Less is known about the involvement of Cullin7 with hepatocellular carcinoma (HCC). In this study, we found that Cullin7 showed a high expression in HCC tumor tissues, especially in metastatic HCC tumor tissues. Also, there was a negative correlation between Cullin7 expression and long survival. Silencing of Cullin7 in liver cancer More >
