Novel CRISPR system could halt growth of triple-negative breast cancer
Triple-negative breast cancer (TNBC), lacking estrogen, progesterone and HER2 receptors, has the highest mortality rate of all breast cancers. It more frequently strikes women under age 50, African American women, and women carrying a BRCA1 gene mutation. The highly aggressive, frequently metastatic cancer is in urgent need of more effective targeted therapeutics. A new tumor-targeted ...

Exploring targeted treatments for children with low-grade brain tumors
Children diagnosed with low-grade astrocytomas, the most common type of pediatric brain tumor, have close to 90 percent overall survival rates. However, the growth of the tumors, as well as the standard treatments (neurosurgery and chemotherapy) required to control them, can cause serious side effects, including damaging developing brains and bodies. Researchers at Dana-Farber/Boston Children’s Cancer and Blood ... Read More about Exploring targeted treatments for children with low-grade brain tumors
Chemical screening suggests a two-pronged treatment for pediatric Ewing sarcoma
For children with Ewing sarcoma, an aggressive bone cancer, a combination of two different classes of drugs may work synergistically to turn off the drivers fueling this disease, finds a new study. The combination appears to be more powerful than relying on either treatment alone. The study, published online last month in Clinical Cancer Research, is the latest in a ...

PET imaging shows if PD-1 cancer immunotherapy is working
PD-1 is a protein on our T cells that normally keeps these immune cells from running amok. A growing number of cancer drugs are designed to inhibit PD-1, enabling patients’ T-cells to attack and kill cancerous cells. PD-1 blockers such as pembrolizumab (Keytruda) have been helpful in treating several cancers including melanoma, non-small cell lung ...

Existing anti-parasitic drug could offer a treatment for Ebola
Amid the worsening Ebola outbreak in the Congo, now threatening to spill into Rwanda, a new study suggests that an existing, FDA-approved drug called nitazoxanide could potentially help contain this deadly, highly contagious infection. In meticulous experiments in human cells, described today in iScience, the drug significantly amplified immune responses to the virus and inhibited ...

A vaccine to prevent opioid overdose?
Sharon Levy, MD, MPH, who directs the Adolescent Substance Use and Addiction Program (ASAP) at Boston Children’s Hospital, was getting her youngest son ready for school, when her husband Ofer, an infectious disease physician at the same hospital, came to her with an offer. The NIH was soliciting proposals to develop an opioid vaccine. Would ... Read More about A vaccine to prevent opioid overdose?
Presidential awardee explores epigenetics via slime molds, worms, and more
Pretty much all of your cells have the same DNA code. Yet they come in an astonishing number of forms. Some cells contract so that your heart can beat or your muscles flex. Others have jobs in your immune system, tuned to recognize different threats. And cells can change their behavior, altering their metabolism for ...

Single-cell sequencing reveals glioblastoma’s shape-shifting nature
Glioblastoma, a cancer that arises in the brain’s supporting glial cells, is one of the worst diagnoses a child can receive. The grade IV, highly malignant tumor aggressively infiltrates healthy brain tissue, and most children die of the disease within one to two years of diagnosis, similar to adults. “The current approach is surgical removal, ...

Pupil dilation and heart rate, analyzed by AI, may offer early autism diagnosis
Autism and other neurodevelopmental disorders often aren’t diagnosed until a child is a few years of age, when behavioral interventions and speech/occupational therapy become less effective. But new research this week in PNAS suggests that two simple, quantifiable measures — spontaneous fluctuations in pupil dilation or heart rate — could enable much earlier diagnosis of ...

Tissue models and a gene therapy for a deadly heart arrhythmia
Catecholaminergic polymorphic ventricular tachycardia (CPVT) is a leading cause of sudden death from cardiac arrest in children and young adults. Marked by racing, irregular heartbeats, the inherited arrhythmia is typically silent until a child suddenly collapses and faints, at an average age of 12. The trigger is an adrenaline surge, caused by exercise or emotional ... Read More about Tissue models and a gene therapy for a deadly heart arrhythmia
