Researchers at the Max Planck Institute have demonstrated an intriguing new way to fight cancer by introducing molecular fibers into cells. While harmless to healthy cells, once these fibers encounter the specific environment of cancer cells they assemble into webs, activating the tumor’s self-destruct sequence. read more

Killing Tumors

Microscopic bubbles could form part of a potent new cancer treatment, according to results from a new study that combines them with ultrasound to blast apart tumor cells

Lately we’ve seen an exciting string of research projects demonstrate how ultrasound can be harnessed to fight cancer, whether that be by helping drugs cross the blood-brain barrier, heating and destroying tissue in prostate cancers, or selectively killing tumor cells while leaving healthy ones unharmed. Adding to this burgeoning potential is a new study that combines ultrasound with microbubbles, which can be blasted apart like a “targeted warhead” to destroy the majority of tumor cells in breast cancer models. read more

Synthetic Compound may turn off Cancer Cells

All cells in the human body have a shelf-life, but those of the cancerous variety use some cunning trickery to outlive their expiry dates and continue spreading throughout the body. Scientists at the University of Tokyo have developed a synthetic version of a fungal compound that could help swing things back in our favor, by reactivating a missing gene that would normally drive these sinister cells to self-destruction. read more

Controlling When to Attack Cancer Cells

Researchers have discovered a way that cancer hides from the immune system – and how to counter it

The immune system is already our best defense against cancer, but sometimes it needs help. After all, cancer has a knack for deceiving it and hiding from immune cells, giving itself time to grow and spread. Now, researchers at QIMR Berghofer Medical Research Institute in Australia have identified one way it does so, and found a method to counter it in mouse tests. read more

Ultrasonic Pulse Therapy for Tumors

Cancer can be a tricky foe, so the best way to fight it might not be with a direct attack, but to cut off its supply lines. One such method, known as gas embolotherapy, involves creating tiny bubbles in the tumor blood vessels, which block the blood supply and starve the cancer out. Now, researchers from China and France have found that the technique could also deal a second blow as a drug delivery system. read more

One of the many ways scientists are working to unravel the mysteries of Alzheimer’s is by conducting experiments on mice that have been genetically engineered to develop the disease. Researchers pondering the protective potential of compounds found in green tea and carrots have again taken this route and returned some promising results, with the Alzheimer’s mice demonstrating unimpaired cognitive function following a carefully designed bout of treatment. read more

Over 65 million years ago, an asteroid some 10 km (6 mi) wide crashed into the Earth and wiped out the dinosaurs. Strangely, the legacy of this huge space rock could include a treatment for cancer after scientists from the UK and China demonstrated that iridium – a rare metal delivered to Earth by the asteroid – can be enlisted to kill cancer without harming healthy cells. read more

Cancer is one of humanity’s biggest killers, but scientists are coming up with some creative ways to fight back. Researchers at the University at Buffalo have developed new kinds of nanoparticles that can infiltrate, heat up and kill cancer cells more effectively and efficiently than similar methods. read more

Alcoholism Drug Fights Cancer

An old drug prescribed to help people stop drinking alcohol may be an effective cancer-killer, according to new study.

The drug, Antabuse, appears to ‘freeze’ cancer in place, preventing them from getting rid of waste, which, ultimately, kills them.

Danish and Czech researchers tested the drug in live mice and human cancer cells and found that it was effective in both without harming other cells.

These findings are not enough to indicate how Antabuse would behave in living people, but the drug is already FDA-approved and its patent is long expired, so if further testing is as promising as this study’s findings, the drug could someday be a cheap alternative cancer treatment. read more

Cancer Drug Kills Every Kind of Tumor

 

Stanford University scientists have discovered a single drug that has killed or shrunk every kind of cancer tumor it has been used against — a new anti-cancer weapon that some have described as a kind of medical Holy Grail.
 
The drug blocks a protein produced in large amounts by cancer cells — called CD47 — that keeps the body’s immune system from fighting tumors. By shutting down the CD47 production, the new antibody drug effectively leaves cancer cells vulnerable to the body’s own natural defense mechanisms.

Tests of the drug found that it destroyed several kinds of human cancer cells transplanted into mice — including breast, ovary, colon, bladder, brain, liver, and prostate tumors — by prompting the rodents’ immune systems to kill the cancer cells.Continue Reading
