Human genome was shaped by an evolutionary arms race with itself

Scientists discovered genes in humans that make repressor proteins to shut down specific jumping genes, a type of retrotransposon. The findings suggest an ongoing battle between mobile DNA sequences and the genes that control them, leading to the evolution of greater genomic complexity.

Many patients lack information about the use of targeted therapies, oncologists say

A survey of 895 doctors in Europe, South America, and Asia revealed that over three-quarters of oncology specialists believe their patients are not well-informed about treatment options. The majority (90%) use biomarker testing to choose treatments, but many identify cost or lack of reimbursement as key barriers.

Is expressive suppression effective in reducing negative emotion?

A recent study found that expressive suppression is effective in reducing negative emotion in Chinese culture, even faster than cognitive reappraisal. The study used high temporal-resolution Event-Related Potentials and a rigorous experimental design to compare the effectiveness of both techniques.

Under-representation of women in oncology leadership positions

A survey of 80 female Greek oncologists found that women are under-represented in leadership positions, with team leaders being men in 82% of cases. The European Society for Medical Oncology launches a new initiative to promote the exchange of ideas among female oncologists and support women with cancer.

Adding cediranib to chemo improves progression-free survival for meta or recurrent cervical cancer

Adding cediranib to standard chemotherapy improves tumour shrinkage and adds a modest improvement in progression-free survival for patients with relapsed or metastatic cervical cancer. The study, published in Annals of Oncology, shows greater tumour shrinkage and increased median progression-free survival compared to chemotherapy alone.
