Developing cancer drugs is challenging. Often, scientists will find a drug that kills cancer cells in a petri dish but fails to act on an actual tumor. Ravid Straussman from the Weizmann Institute of Science and Todd Golub from Harvard Medical School think that in situ, bacteria can protect cancer cells from drugs. To test their theory, Staussman and Golub mixed some healthy skin cells with cells from a … Continue reading Bacteria May Help Protect Cancer Cells
Glioblastoma is one of the most deadly brain cancers because it is nearly impossible to destroy the cause of the cancer: cancerous stem cells. However, scientists are using Zika’s preference for stem cells to target and eliminate the cancerous stem cells in adults. The preliminary study shows the viability of this method, but more thorough research and a PR campaign may be necessary before Zika treatments for brain cancer can become standard protocol. Continue reading Could Zika become a treatment for brain cancer?
3D printing is poised to become a major technological advancement in treating injuries and illnesses that cause tissue damage. For scientists, creating artificial tissue with 3D printing has been a challenge. As the 3D printed structure grows in size, cells often move and compromise the tissue’s structural integrity. New work from Oxford University addresses this problem. By encasing cells in nanoliter sized droplets of fat molecules, researchers are able … Continue reading Scientists Learn to 3D Print Cells One Drop at A Time
What is the difference between a normal cell and a cancer cell? The answer lies in their DNA. Cancer results from the accumulation of genetic mutations, which trigger uncontrolled cell growth. Cancer’s mutated DNA can reveal its presence early on in the disease. Like leaving fingerprints at a crime scene, tumor cells release small pieces of DNA into the bloodstream. This “circulating tumor DNA” can now … Continue reading Catching Cancer: Blood Test for Early-Stage Diagnosis
A medical team at Johns Hopkins University genetically engineered a common cold virus to deposit a gene when injected into the human eye. This gene codes for a protein that binds to VEGF, another protein whose activity in old age contributes to vision loss (a disease called AMD or wet AMD). This small clinical study’s preliminary results show that just one small dose is potent enough to improve a patient’s vision loss. Continue reading Genetically engineered viruses: a medicine of the future
Chemotherapy is a common and dangerous cancer treatment due to the negative effects on everything that is not a tumor cell. Researchers from Columbia University have invented a soft medical implant capable of administering drugs from inside the body. The ability to place this device close to the target area allows for a significant (90%) reduction of the drug dosage to be used. Similarly, avoiding body-wide administration of the drug can greatly reduce the damage inflicted by normal chemotherapy dosages. Continue reading A new medical implant might greatly reduce the risk of chemotherapy treatment
by Dan Tarjan figures by Krissy Lyon The EpiPen, the antiparasitic drug Daraprim, the blood pressure medication Nitropress. These life saving drugs have recently been in the news because their prices spiked by over 100% year-to-year without any apparent reason except increasing profits. And they’re not alone. Across the US healthcare industry, specialty drug prices are rising. These brand name products marked a 16.2% increase … Continue reading Should we pay for drugs or cures? How tracking drug effectiveness could improve US healthcare spending
