Skin cancer warning: The one sign other than a mole you need to watch out for

Skin cancer symptoms usually depend on the type of skin cancer it is. There are two main types – melanoma and non-melanoma. Melanoma is more serious and usually distinguished by a mole changing shape, an itchy or sore mole or a mole that bleeds, crusts or scabs. But non-melanoma is associated with a different set of symptoms. An itchy spot […]

Öko-Test: Many of the sensitive sun creams in the Test is not recommended

Öko-Test is sensitive to sun cream: Four out of five products is not recommended Sun cream should protect the skin against the negative effects of the sun’s rays, which, according to the sun poor months particularly important. However, all of the available sunscreens do not provide adequate protection and possible risks of critical ingredients added. “Öko-Test” has now examined 20 […]

New findings could lead to improved vaccinations against sexually transmitted infections

In a study published today in the Nature Communications, researchers from King’s College London have shown how skin vaccination can generate protective CD8 T-cells that are recruited to the genital tissues and could be used as a vaccination strategy for sexually transmitted infections (STIs). One of the challenges in developing vaccines for STIs, such as HIV or herpes simplex virus, […]

A new way to wind the development clock of cardiac muscle cells

These days, scientists can collect a few skin or blood cells, wipe out their identities, and reprogram them to become virtually any other kind of cell in the human body, from neurons to heart cells. The journey from skin cell to another type of functional cell involves converting them into induced pluripotent stem cells (iPSCs), which are similar to the […]

Conquering cancer’s infamous KRAS mutation

KRAS is one of the most challenging targets in cancer. Despite its discovery more than 60 years, researchers still struggle to inhibit its mutated form — earning its reputation as “undruggable.” Yet, the hunt for an Achilles’ heel continues, as cancers driven by KRAS mutations are both common and deadly. Now, scientists from Sanford Burnham Prebys and PHusis Therapeutics have […]

Removal of gene completely prevents development of aggressive pancreatic cancer in mice

The action of a gene called ATDC is required for the development of pancreatic cancer, a new study finds. The work builds on the theory that many cancers arise when adult cells — to resupply cells lost to injury and inflammation — switch back into more “primitive,” high-growth cell types, like those that drive fetal development. When this reversion happens […]

Biologists design new molecules to help stall lung cancer: Scientists tie tumor growth to heme availability, build peptide to ‘hijack’ uptake

University of Texas at Dallas scientists have demonstrated that the growth rate of the majority of lung cancer cells relates directly to the availability of a crucial oxygen-metabolizing molecule. In a preclinical study, recently published in Cancer Research, biologist Dr. Li Zhang and her team showed that the expansion of lung tumors in mice slowed when access to heme — […]

Discovery of oral cancer biomarkers could save thousands of lives

Oral cancer is known for its high mortality rate in developing countries, but an international team of scientists hope its latest discovery will change that. Researchers from the University of Otago, New Zealand, and the Indian Statistical Institute (ISI), Kolkata, have discovered epigenetic markers that are distinctly different in oral cancer tissues compared to the adjacent healthy tissues in patients. […]

Cancers ‘change spots’ to avoid immunotherapy

Cancers can make themselves harder for new immunotherapies to see by ‘changing their spots’ — and switching off a key molecule on the surface of cells that is otherwise recognised by treatment. Researchers found that they could test samples from patients with bowel cancer to identify which were most likely to respond to immunotherapy by assessing molecular changes within miniature […]
