Consider the tightly orchestrated suicide of cells—a phenomenon essential to everything from shaping an embryo to keeping it free of cancer later in life. When cells refuse to die, and instead multiply uncontrollably, they become what we call tumors. An intricate circuitry of biochemical reactions inside cells coordinates their self-sacrifice. Tracing that circuitry is, naturally, an important part of cancer research. http://medicalxpress.com/news/2012-09-uncovers-mechanism-tumor-suppressor-mig6.html Cancer Mon, 24 Sep 2012 09:41:26 EST news267698476 Inhibitors of indoleamine 2,3-dioxygenase (IDO) are being assessed in clinical trials as a potential treatment for recurrent or refractory solid tumors. Clear genetic rationale for these trials, together with evidence that primary and metastatic lung tumors might be particularly susceptible to the drugs, is now reported in a preclinical study published in Cancer Discovery, a journal of the American Association for Cancer Research. http://medicalxpress.com/news/2012-07-preclinical-ongoing-clinical-trials-ido.html Cancer Thu, 19 Jul 2012 10:39:19 EST news261913115 Stroke patients treated who received hormonal treatment, combined with rehabilitation, performed better on functioning and reasoning tests than patients who received rehabilitative therapy alone, a new clinical study from Italy shows.

The driver behind these phenomena is a molecule called parathyroid hormone related protein (PTHrP), which is secreted by the mammary glands. The signal that regulates the secretion of PTHrP, and where this other unknown molecule exerts its influence, has remained a mystery. Now, in a new study using cells and tissues from mice, cows, and people, a team of researchers at the University of Cincinnati have identified this mystery molecule as serotonin, a neurotransmitter most often recognized for its role in happiness and well-being. The scientists also identified the specific receptor that serotonin acts on in mammary tissue. Understanding these two findings more deeply could lead to better ways to combat bone loss, potentially by using drugs that affect serotonin signaling. http://medicalxpress.com/news/2012-02-serotonin-large-role-bone-loss.html Medical research Tue, 21 Feb 2012 13:00:01 EST news249046859
