Killing cancer by protecting normal cells

Researchers developed an anti-cancer drug that protects normal cells from radiation damage while sparing cancer cells. The compound, RTA 408, increases the effectiveness of radiation therapy in prostate cancer models and has potential applications for treating accidental radiation exposure.

Molecule fights cancer on 2 fronts

Researchers have developed a synthetic anti-cancer molecule JK-31 that blocks the signalling of a 'growth factor' chemical promoting blood vessel networks to feed tumours. The molecule also inhibits a protein controlling cancer cell division and proliferation.

NSAIDs prevent colon cancer by inducing death of intestinal stem cells that have mutation

NSAIDs protect against colorectal cancer by inducing cell suicide pathways in intestinal stem cells carrying a mutated gene. The research team found that NSAIDs activate the so-called death receptor pathway, selectively triggering a suicide program in dysfunctional cells. This mechanism could help design new drugs to prevent colon cancer.

Herbal medicines could contain dangerous levels of toxic mold

A recent study found that 43% of medicinal plants in Pakistan were naturally contaminated with toxins produced by moulds. The levels exceeded permissible limits in 70% of the samples, and 31% produced harmful toxins. This highlights a need for stricter regulation to protect people using herbal medicines.

Findings point to an 'off switch' for drug resistance in cancer

Researchers at the Salk Institute have discovered a mechanism for cancer cells to become resistant to chemotherapy, which may lead to a new approach to treating cancer. The study found that variations in breast cancer cells' RNA enable the cancer to evolve and adapt more quickly than previously thought.

Tuning light to kill deep cancer tumors

A novel strategy combining nanoparticle technology with FDA-approved photodynamic therapy has been developed to effectively kill deep-set cancer cells in vivo. The treatment uses low-power, deep-tissue-penetrating light to activate the cancer-killing drug, showing improved destruction of tumors with minimal damage to surrounding tissue.

Patient's dramatic response and resistance to cancer drug traced to unsuspected mutations

Researchers at Dana-Farber Cancer Institute identified two previously unknown mutations in a cancer patient's DNA that led to an extraordinary response to the drug everolimus. The study highlights the potential of personalized medicine and may help develop new therapeutic strategies for other patients with similar mutations.

Targeted treatment could halt womb cancer growth

Researchers have found a targeted treatment, afatinib, that can stop the growth of aggressive womb cancer cells and shrink tumours. The drug targets faults in the HER2 gene, which lie at the heart of the cancer cells, offering new hope for patients with this rare but deadly form of cancer.
