Protein Identified as Possible Universal Therapeutic Target for Many Infections, Including Ebola

Virginia Commonwealth University scientists, writing in the Journal of Cellular Physiology, reveal that the GRP78 protein could be a universal therapeutic target capable of treating certain cancers as well as antibiotic-resistant infections. The researchers discovered that by attacking GRP78 via a drug combination of already approved drugs, they could destroy brain cancer cells and stop a variety of infectious diseases. With further research, this new approach could lead to compounding breakthroughs in protein-targeting treatments.

Small Molecule Successfully Targets Telomerase to Destroy Cancer Cells
Scientists at UT Southwestern Medical Center, writing in the journal Cancer Discovery, report new advances in targeting telomerase with small molecule drugs to destroy cancer cells and slow down tumor growth. In a mouse study, the researchers found that the 6-thiodG molecule slowed the growth of cancer tumors by signaling to the cancer cell via the telomere that damage had taken place to the cell itself, causing it to stop dividing and eventually die. With further research, this new method of telomerase targeting could prove useful in new cancer treatments.

“Flying Carpet” Technique Uses Graphene to Deliver One-Two Punch of Anticancer Drugs
New work appearing in the journal Advanced Materials discusses the creation of a graphene film containing two anticancer drugs, which proved successful in delivering two types of drugs to tumors in a mouse model. One drug, for example, works best when attached to the outer membrane of cancer cells and was applied to the surface of the graphene film. The other, used to target the nucleus, was bound to the graphene itself. This new technique for delivering combination-therapy cancer treatment could lead to compounding breakthroughs in anticancer research.

Injectable 3D cell factories to fight cancer in the body
Researchers at Harvard University and the Wyss Institute are developing an injectable biomaterial that forms a tiny scaffold in the body which can be used to re-program cells and trigger an immune response to fight cancer and infectious diseases.

Muy interesante!

Un telómero es un capuchón formado por seis proteínas, que está situado en los extremos de los cromosomas y que sirve para proteger la información genética del organismo. Los investigadores españoles han utilizado una de las seis proteínas (o shelterinas) que protegen a los telómeros, la TRF1, y al bloquearla consiguieron destruir este escudo protector de los cromosomas del cáncer, cuyas células mueren de forma inmediata.

Claro, mira este hilo: salud-f106/telomeros-t1707.html

Yo tomo tomo Astragalus en cantidad, es bastante barato! suplementos-vitaminas-f114/astragalus-t1630.html

Scientists have designed microscopic "grenades" that can explode their cancer-killing payload in tumours.
The team will present its findings at the National Cancer Research Institute conference next week.
They plan to use liposomes - tiny bubbles of fat which carry materials round the body - to release toxic drugs when their temperature is raised.
The "grenades" are intended to avoid side-effects by ensuring the drugs target only the tumour.
Experts said such technology, which has been effective in animal experiments, was the "holy grail of nanomedicine".
Cancer scientists are trying to harness the transporting abilities of these fatty spheres by getting them to carry toxic drugs to tumours.

Un virus para elimnar el cancer?

BY THE NUMBERS, the newest FDA-approved treatment for skin cancer doesn’t seem a real game changer. A $65,000 course of treatment extends melanoma patients’ lives by less than four and a half months, on average—and that result is barely statistically significant.

It’s how the new drug—Imlygic, made by the biotechnology company Amgen—works that has the oncology world so worked up. Imlygic is a virus—alive and infectious, the first to get a stamp of approval in the US for its ability to attack cancer cells. It opens a whole new front in the fight against cancer, which has the sneaky habit of coming back after chemotherapy, radiation, or surgery. “It is a totally new class of weapons that we can now use,” says Antonio Chiocca, a neurosurgeon at Brigham and Women’s Hospital. And the armory could be bigger, because coming up right behind Imlygic are over a dozen clinical trials for more anti-cancer viruses.

'Suicide' gene therapy kills prostate cancer cells.

A new gene therapy technique is able to modify prostate cancer cells so that a patient's body attacks and kills them, US scientists have discovered.

Their research found a 20% improvement in survival in patients with prostate cancer five years after treatment.
