• Function: Fibronectins bind cell surfaces and various compounds including collagen, fibrin, heparin, DNA, and actin. Fibronectins are involved in cell adhesion, cell motility, opsonization, wound healing, and maintenance of cell shape. Involved in osteoblast compaction through the fibronectin fibrillogenesis cell-mediated matrix assembly process, essential for osteoblast mineralization. Participates in the regulation of type I collagen deposition by osteoblasts. Acts as a ligand for the LILRB4 receptor, inhibiting FCGR1A/CD64-mediated monocyte activation.

Type(s) of Resistant Mechanism of This Molecule

  UAPP: Unusual Activation of Pro-survival Pathway

Drug Resistance Data Categorized by Drug

Approved Drug(s) 3 drug(s) in total

Epothilone B

Drug Sensitivity Data Categorized by Their Corresponding Mechanisms

Unusual Activation of Pro-survival Pathway (UAPP)

Disease Class: Endometrial cancer [1]

• Sensitive Disease: Endometrial cancer [ICD-11: 2C76.1]
• Sensitive Drug: Epothilone B
• Molecule Alteration: Expression; Down-regulation
• Experimental Note: Revealed Based on the Cell Line Data
• Cell Pathway Regulation: Cell migration; Inhibition; hsa04670
• In Vitro Model: Hec50 cells; Endometrium; Homo sapiens (Human); CVCL_2929
• Experiment for Molecule Alteration: Immunoblotting analysis
• Experiment for Drug Resistance: ELISA assay
• Mechanism Description: Low or absent miR-200c results in aberrant expression of ZEB1 and consequent repression of E-cadherin. Reinstatement of miR-200c to such cells restores E-cadherin and dramatically reduces migration and invasion. One such gene, class IIIbeta-tubulin (TUBB3), which encodes a tubulin isotype normally found only in neuronal cells, is a direct target of miR-200c. Restoration of miR-200c increases sensitivity to microtubule-targeting agents by up to 85%. Since expression of TUBB3 is a common mechanism of resistance to microtubule-binding chemotherapeutic agents in many types of solid tumors, the ability of miR-200c to restore chemosensitivity to such agents may be explained by its ability to reduce TUBB3.
