    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. clonidine dosage for hypertension Here, we propose a new strategy for the treatment of early cancerous lesions and advanced metastatic disease, via the selective targeting of cancer stem cells (CSCs), a.k.a., tumor-initiating cells (TICs). We searched for a global phenotypic characteristic that was highly conserved among cancer stem cells, across multiple tumor types, to provide a mutation-independent approach to cancer therapy. This would allow us to target cancer stem cells, effectively treating cancer as a single disease of “stemness”, independently of the tumor tissue type. Using this approach, we identified a conserved phenotypic weak point – a strict dependence on mitochondrial biogenesis for the clonal expansion and survival of cancer stem cells. Interestingly, several classes of FDA-approved antibiotics inhibit mitochondrial biogenesis as a known “side-effect”, which could be harnessed instead as a “therapeutic effect”. Based on this analysis, we now show that 4-to-5 different classes of FDA-approved drugs can be used to eradicate cancer stem cells, in 12 different cancer cell lines, across 8 different tumor types (breast, DCIS, ovarian, prostate, lung, pancreatic, melanoma, and glioblastoma (brain)). These five classes of mitochondrially-targeted antibiotics include: the erythromycins, the tetracyclines, the glycylcyclines, an anti-parasitic drug, and chloramphenicol.

Oct 8, 2018. Metastasis and recurrence are huge challenges for breast cancer researchers. which are two of the biggest challenges in cancer treatment. outline the potential use of an antibiotic called doxycycline to clear up CSCs.

    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. Background and objectives: Cancer stem cells (CSCs) have been implicated in tumor initiation, recurrence, metastatic spread and poor survival in multiple tumor types, breast cancers included. CSCs selectively overexpress key mitochondrial-related proteins and inhibition of mitochondrial function may represent a new potential approach for the eradication of CSCs. Because mitochondria evolved from bacteria, many classes of FDA-approved antibiotics, including doxycycline, actually target mitochondria. Our clinical pilot study aimed to determine whether short-term pre-operative treatment with oral doxycycline results in reduction of CSCs in early breast cancer patients. Methods: Doxycycline was administered orally for 14 days before surgery for a daily dose of 200 mg. Immuno-histochemical analysis of formalin-fixed paraffin-embedded (FFPE) samples from 15 patients, of which 9 were treated with doxycycline and 6 were controls (no treatment), was performed with known biomarkers of “stemness” (CD44, ALDH1), mitochondria (TOMM20), cell proliferation (Ki67, p27), apoptosis (cleaved caspase-3), and neo-angiogenesis (CD31). For each patient, the analysis was performed both on pre-operative specimens (core-biopsies) and surgical specimens.

    If you take Adderall, you likely know that it’s a stimulant medication often used to treat attention deficit hyperactivity disorder (ADHD). It can help you pay attention, stay alert, and concentrate. It can also help you avoid impulsive and hyperactive behaviors. Xanax, on the other hand, is a drug called a benzodiazepine. It's used to treat generalized anxiety disorder and panic disorder. Xanax can make you feel calmer, more relaxed, and even drowsy. If you’re wondering if you can take these two drugs together, you’re right to do some research.

    The Patient Information Leaflet (PIL) is the leaflet included in the pack with a medicine. It is written for patients and gives information about taking or using a medicine. It is possible that the leaflet in your medicine pack may differ from this version because it may have been updated since your medicine was packaged. Below is a text only representation of the Patient Information Leaflet. The original can be viewed in PDF format using the link above. What Ciproxin is and what it is used for Ciproxin contains the active substance ciprofloxacin. The text only version may be available from RNIB in large print, Braille or audio CD. Ciprofloxacin is an antibiotic belonging to the fluoroquinolone family. For further information call RNIB Medicine Leaflet Line on 08. Ciprofloxacin works by killing bacteria that cause infections. Ciprofloxacin may be used in the management of patients with low white blood cell counts (neutropenia) who have a fever that is suspected to be due to a bacterial infection.
