We have a general idea of the timing of and the hormones involved in ovulation in humans. What we don’t understand are the precise mechanics regulating how the egg escapes from the follicle of cells encasing it in the ovary…
Their findings, reported in Nature Communications, suggest that inhibiting the gene, protein kinase D1 (PKD1), and its protein could halt progression and spread of this form of pancreatic cancer, and possibly even reverse the transformation. “As soon as pancreatic cancer develops, it begins to spread, and PKD1 is key to both processes. Given this finding, we are busy developing a PKD1 inhibitor that we can test further,” says the study’s co-lead investigator, Peter Storz, Ph.D., a cancer researcher at Mayo Clinic…
“The FDA approval has expanded treatments options for many metastatic breast cancer patients, but these new results are showing how effective the drug can also be for breast cancer patients who have already tried endocrine therapies and may be running out of options,” said lead investigator Angela DeMichele, MD, MSCE, associate professor in the division of Hematology/Oncology and Epidemiology and co-leader of the Breast Cancer Research Program at the Abramson Cancer Center. “Combined with the promising results from other trials looking at the effectiveness of this drug, our results indicate that palbociclib can extend the duration of disease control and produce tumor shrinkage in patients with estrogen-receptor positive (ER+) breast cancer, without the debilitating side effects of chemotherapy.” The newly-published phase II trial primarily sought to evaluate disease response and control, while monitoring for the presence of side effects such as neutropenia, an abnormally low white blood cell count. Patients enrolled in the trial had previously undergone several prior chemotherapy and hormonal regimens for metastatic disease…
Study lead Menashe Bar-Eli, Ph.D., professor of Cancer Biology, reported a previously unknown target for CREB (cAMP response element-binding protein), a transcription factor that regulates other transcription factors involved in melanoma development. …
“It was surprising to find that cabazitaxel functions differently than docetaxel in killing cancer cells, even though they’re both taxanes,” says senior author Karen Knudsen, Ph.D., Interim Director of the Sidney Kimmel Cancer Center and a professor of cancer biology at the Sidney Kimmel Medical College at Thomas Jefferson University. “It shows that we may not be taking full advantage of this next generation taxane in the clinic.” For years, docetaxel has been the only effective chemotherapy for men whose cancer was no longer responding to hormone treatments…
Their work, described in a paper published this week in the journal Review of Scientific Instruments, from AIP Publishing, demonstrates the potential of the device to be used as a breathalyzer for early lung cancer detection — possibly a safe and effective method of detecting cancer early that may save lives. According to the researchers, the laboratory results are promising, but the device would still need to prove effective in clinical trials before its widespread adoption as a diagnostic tool. “Our results show that the device can discriminate different kinds and concentrations of cancer related volatile organic compounds with a nearly100 percent accurate rate,” said Jin-can Lei, the primary researcher and a postdoc from the College of Optoelectronic Engineering, Chongqing University. “This would also be a rapid method in that the entire detection process in our experiment only takes about 20 minutes.” Based on a small, circular plate called fluorescent cross-responsive sensor array, a specially-designed rotary gas chamber and a data collection and processing system, the device can detect lung cancer related gases at very low concentration, or below 50 parts per billion (ppb), showing a potential to identify lung cancer at the early stage. …
In a study published in Molecular Metabolism, Saint Louis University researchers have tested in an animal model a promising drug candidate that stopped fatty liver disease from progressing to the stage that causes severe liver damage. …
