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.
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.
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.
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.
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.
