Recent work in cancer cell metabolism has led to the elucidation of the significance of the Warburg effect to cancer 3 , 4.
In essence, glycolysis in non-dividing cells is followed by complete oxidation of pyruvate in mitochondria, producing the end product of CO2. This leads to a complete oxidation of glucose without biomass accumulation.
In contrast, in cancer cells, the pyruvate flux into mitochondria is reduced as the result of aerobic glycolysis. These pathways generate NADPH and metabolic intermediates such as ribose, providing the reducing agent and building blocks for biosynthesis required for biomass accumulation needed for cell proliferation 3 — 5.
Thus, targeting aerobic glycolysis, which in turn diminishes the production of reducing agents and building blocks for cancer cell biosynthesis, can be an effective and likely a universal anti-cancer strategy. Inside mitochondria, as illustrated in Fig.
The electrons then feed into the electron transport chain ETC residing in the mitochondrial inner membrane, which pumps protons out across the membrane and generates a proton gradient. Usually, the ETC activity is coupled to the energy requirement of the cells. When the energetic requirement is met, ETC and oxidation of acetyl-CoA are shut down, along with pyruvate flux into mitochondria. Mitochondrial uncoupling is a process that leads to proton influx across the mitochondrial inner membrane without passing through ATP synthase 6 — 9.
As illustrated in Fig.
To meet the cellular energy demand, the flux of pyruvate into mitochondria is expected to accelerate, which promotes the complete oxidation of glucose. This mode of metabolic change induced by mitochondrial uncoupling could potentially diminish the anabolic effect of aerobic glycolysis.
Niclosamide was an FDA approved anthelmintic drug for treating tapeworm infection 11 , Its mechanism of action is to uncouple mitochondria 11 — Recent studies have found that niclosamide has strong in vitro anti-cancer activity against a wide arrange of cancer cells, including cells from colon cancer 14 , 15 , breast cancer 16 — 20 , glioma 21 , hepatocellular carcinoma 22 , adrenocortical carcinoma 23 , ovarian tumor 24 , osteosarcoma 25 , prostate cancer 26 , 27 , and many other cancer types 28 , Oxyclozanide is another mitochondrial uncoupling anthelmintic drug approved for veterinary use Oxyclozanide has not yet been reported in literature to have any anti-cancer activity.
We decided to use niclosamide and oxyclozanide as prototype drugs to examine the impact of mitochondrial uncoupling on cancer glucose metabolism and to determine their potential anti-cancer activities and particularly in vivo anticancer efficacy. NEN niclosamide ethanolamine is the ethanolamine salt of niclosamide, which has a similar excellent safety profile as niclosamide 11 , 12 , 32 , 33 and better systemic exposure Our recent studies showed that NEN has high levels of distribution in the liver after oral administration, where it uncouples mitochondria, reduces liver steatosis, and increase insulin sensitivity By reducing the number of colors, bit PNG files can be converted to much smaller 8-bit indexed color images.

Use the optimized image to save bandwidth and loading time and your website visitors will thank you. Is it supported everywhere? The files produced by TinyPNG are displayed perfectly on all modern browsers including mobile devices.
Still need to support Internet Explorer 6? It normally ignores PNG transparency and displays a solid background color. With TinyPNG the background becomes transparent again. Binary transparency without any workarounds! Is it safe to use animated PNG? Only Microsoft Edge does not support the format yet.
