We previously discovered that tetracyclines increase the expression of lipid phosphate phosphatases at the surface of cells. These enzymes degrade circulating lysophosphatidate and therefore doxycycline increases the turnover of plasma lysophosphatidate and decreases its concentration. Extracellular lysophosphatidate signals through six G protein-coupled receptors and it is a potent promoter of tumor growth, metastasis and chemo-resistance. These effects depend partly on the stimulation of inflammation that lysophosphatidate produces. In this work, we used a syngeneic orthotopic mouse model of breast cancer to determine the impact of doxycycline on circulating lysophosphatidate concentrations and tumor growth. Cytokine/chemokine concentrations in tumor tissue and plasma were measured by multiplexing laser bead technology. Leukocyte infiltration in tumors was analyzed by immunohistochemistry. doxycycline bacterial coverage One of the most commonly held beliefs is that cancer cells contain so many genetic mutations that the only way to deal with them is to destroy or remove them by conventional oncological methods such as surgery, chemotherapy and radiation. New research has shown, however, that by altering one specific oncogene in cancer cells, Myc (pronounced “mick”), one can, in essence, turn “off” certain forms of aggressive malignant cells. Myc plays an essential role in all cellular life cycles. This protein sends the message for the cell to divide. In normal cells, this protein is only made when it’s the proper time for the cell to divide and multiply. In cancer cells, however, Myc is overproduced which results in uncontrolled and constant cell division and replication. This uncontrolled cellular activity results in tumor growth.

Tumor heterogeneity can be traced back to a small subset of cancer stem. sensitive to mitochondrial targeting antibiotics such as doxycycline. "Vitamin C and antibiotics could be up to 100 times more effective than drugs at killing cancer cells – without the side effects," reports the Mail Online. The news comes from the results of a study that found a new two-pronged approach using the antibiotic doxycycline followed by vitamin C could kill cancer cells. Doxycycline killed many cancer cells, but others became resistant. The resistant cells were then destroyed by vitamin C. While this is encouraging news, it needs to be put into context. Researchers used human breast cancer stem cells, but didn't perform any studies on animals or humans. This means we don't know how successful this strategy could be – and the Mail's claim there would be no side effects is unsupported. Though both doxycycline and vitamin C are safe to use in humans, more research is needed to find out how they interact with other cancer treatments and therapies before this can be recommended as a new approach to treating cancer. Alex Speers ND, MS Within a single tumor, there are a variety of different cell types. One type, called cancer stem cells, or CSCs, are unique because when they divide, they can produce a variety of different cell types in addition to producing more stem cells. This is important because it means that if CSCs are present within a tumor, that tumor has a potential source for any cell type it needs to sustain itself and grow. Now consider what happens when we try to kill a growing tumor. Even if a treatment successfully kills a significant number of cancer cells, that tumor may still be able to regrow if CSCs remain alive. Think of cancer like a weed, growing wildly inside the body. CSCs are the root, and as any good gardener knows, if you don’t kill the root, there’s a good chance that weed will eventually grow back.
