An estrogen receptor that promotes cancer also causes drug resistance Posted: 23 Sep 2021 09:24 AM PDT Cancer cells proliferate despite a myriad of stresses -- from oxygen deprivation to chemotherapy -- that would kill any ordinary cell. Now, researchers have gained insight into how they may be doing this through the downstream activity of a powerful estrogen receptor. The discovery offers clues to overcoming resistance to therapies like tamoxifen that are used in many types of breast cancer. |
Antibody-producing B cells may be 'predestined' for their fates Posted: 23 Sep 2021 08:56 AM PDT The master regulator behind the development of antibody-producing cells has been identified in a new study. The findings provide new insight into the inner workings of the immune system and may help understand how tissues develop and how certain cancers arise. |
How tactile vibrations create illusions Posted: 23 Sep 2021 08:56 AM PDT Among the traditional five human senses, touch is perhaps the least studied. Yet, it is solicited everywhere, all the time, and even more so in recent years with the widespread daily use of electronic devices that emit vibrations. Indeed, any moving object transmits oscillatory signals that propagate through solid substrates. Our body detects them by means of mechanoreceptors located below the skin and transmits the information to the brain similarly to auditory, olfactory or visual stimuli. By studying how mice and humans perceive tactile vibrations, researchers discovered that the brain does not reliably perceive the frequency of a vibration when its amplitude varies. An illusory phenomenon is thereby created, which highlights how far our perception of the world around us can deviate from its physical reality. |
Researchers define chain of events leading to dangerous intestinal disorder in preemies Posted: 23 Sep 2021 08:56 AM PDT A research team has provided what may be the most definitive view to date of the biological process leading to necrotizing enterocolitis (NEC), a dangerous inflammatory disease that can destroy a premature infant's intestinal lining and causes death in up to a third of the cases. |
Breast cancers: Ruptures in cell nuclei promotes tumor invasion Posted: 23 Sep 2021 08:56 AM PDT When cells multiply and migrate, they can be compressed and their nucleus may break open. This phenomenon causes DNA damage. Scientists have now shown that this facilitates the spread of cancer cells in breast tumors. |
Child abuse and neglect linked to early death in adulthood Posted: 23 Sep 2021 08:56 AM PDT A new study found that adults who reported experiencing sexual abuse by the age of 16 had a 2.6 times higher risk of dying in middle age -- that is, between 45 and 58 -- than those who did not report sexual abuse. |
Adjusting fatty acid intake may help with mood variability in bipolar disorders Posted: 23 Sep 2021 08:56 AM PDT Can specific dietary guidelines help people living with bipolar disorders better manage their health? Clinical trial results showed that a diet designed to alter levels of specific fatty acids consumed by participants may help patients have less variability in their mood. |
A new method for removing lead from drinking water Posted: 23 Sep 2021 08:56 AM PDT Engineers designed a relatively low-cost, energy-efficient approach to treating water contaminated with heavy metals such as lead. |
Deadly virus’s pathway to infect cells identified Posted: 23 Sep 2021 08:56 AM PDT Researchers have discovered how Rift Valley fever virus enters cells, pointing the way to new therapies to treat deadly Rift Valley fever. |
Therapy using dual immune system cells effectively controls neuroblastoma Posted: 23 Sep 2021 08:56 AM PDT A newly developed immunotherapy that simultaneously uses modified immune-fighting cells to home in on and attack two antigens, or foreign substances, on cancer cells was highly effective in mice implanted with human neuroblastoma tissue. |
Metastatic prostate cancer comes in two forms, which could guide treatment Posted: 23 Sep 2021 08:55 AM PDT Scientists have identified two subtypes of metastatic prostate cancer that respond differently to treatment, information that could one day guide physicians in treating patients with the therapies best suited to their disease. |
Infection hinders blood vessel repair following traumatic brain or cerebrovascular injuries Posted: 23 Sep 2021 08:55 AM PDT Traumatic brain injury (TBI) and other injuries to blood vessels in the brain, like stroke, are a leading cause of long-term disability or death. Researchers have found a possible explanation for why some patients recover much more poorly from brain injury if they later become infected. |
Posted: 23 Sep 2021 08:55 AM PDT Poxviruses have found a unique way of translating their genes into proteins in the infected organism. Scientists of the have been able to gain atomic-level insights into the functioning of the molecular machinery involved in the process. |
