In particular, the PC-loaded EFM exerted its anti-cancer activity by blocking the cell cycle at the G0/G1 phase and inducing cell apoptosis involving the decrease of Bcl-2/Bax, activation of caspase 3 and release of cytochrome c. This study suggests that co-axial electrospinning is an efficient and effective way to deliver PC and improve its bioavailability; thus, it represents a promising approach for encapsulating functional ingredients for colon cancer prevention.
To investigate the molecular mechanisms of cordycepin against colon cancer and in driving apoptosis, p53 and Bcl‑2‑like protein 4‑null (Bax‑/‑) colon cancer HCT116 cell lines were used.
We have demonstrated the therapeutic potential of miR-15a in colon cancer. miR-15a inhibits several important genes (<i>BCL2, BMI1, YAP1</i> and <i>DCLK1</i>), decreasing cancer progression and resistance.
The expressions of C-MYC and BCL-2 in colon cancer tissues exhibited high levels of expression, while miR-184 displayed relatively low levels in comparison to the adjacent normal tissues.
This investigation was conducted to construct a hypoxia/colorectal dual-specific bidirectional short hairpin RNA (shRNA) expression vector and to transfect it into the colon cancer cell line HT-29 with PEI/chitosan-TBA nanoparticles for the simultaneous knock down of β-catenin and Bcl-2 under hypoxia.
Using HCT-116 human colon cancer cell line, expression of AMPK, extracellular signal-regulated kinase (ERK), cyclin D1, and Bcl-2 was investigated and cell cycle arrest was assessed.
The loss of Bcl-2 expression appears to be correlated with increase in number of relapses in the stage II colon cancers and could be a potential useful additional histo-prognostic marker in therapy decision making.
gamma-Secretase inhibitors abrogate oxaliplatin-induced activation of the Notch-1 signaling pathway in colon cancer cells resulting in enhanced chemosensitivity.
Our results indicate that early apoptosis and cell death of human colon cancer cells induced by photodynamic therapy with lysosome-localizing photosensitizer ATX-S10Na (II) are mediated by p53-Bax network and low levels of Bcl-2 and Bcl-x(L) proteins.
Bcl-2 overexpression in PhIP-induced colon tumors: cloning of the rat Bcl-2 promoter and characterization of a pathway involving beta-catenin, c-Myc and E2F1.
Studies on p53, BAX and Bcl-2 protein expression and microsatellite instability in stage III (UICC) colon cancer treated by adjuvant chemotherapy: major prognostic impact of proapoptotic BAX.
We examined whether 5F could affect apoptosis in human colon cancer HT-29 cells, and test whether and how the over-expression of Bcl-2 and Bcl-xL could offset the effect of 5F on cell growth.
This study suggested that a PPARgamma-Bcl-2 feedback loop may function to control the life-death continuum in colonic cells and that a deficiency in generation of PPARgamma ligands may precede the development of human colon cancer.
