Micromet Presents Update On Blinatumomab's Response Rate And Duration In A Phase 1 Study In Non-Hodgkin's Lymphoma Patients
Micromet, Inc. (Nasdaq: MITI), a biopharmaceutical company developing novel, proprietary antibodies for the treatment of cancer, inflammation and autoimmune diseases, last week presented an update from an ongoing clinical study of the BiTE(R) antibody blinatumomab (MT103) for non-Hodgkin"s lymphoma (NHL) at the 14th Congress of the European Hematology Association (EHA), held June 4 to 7 in Berlin, Germany. Blinatumomab is a novel therapeutic antibody that activates a patient"s T cells to seek out and destroy cancer cells.

Democratic Female Senators Praise Supreme Court Nominee Sotomayor
Several Democratic female senators on Wednesday took to the floor in a series of speeches praising Supreme Court nominee Sonia Sotomayor and highlighting her judicial qualifications, the Boston Globe"s "Political Intelligence" reports. Sen. Amy Klobuchar (Minn.) -- a member of the Senate Judiciary Committee -- was joined by Sens. Mary Landrieu (La.), Claire McCaskill (Mo.) and Jeanne Shaheen (N.H.).In her address, Klobuchar said that Sotomayor"s experience "particularly resonated with me," adding that Sotomayor "understands the law is not just some dusty book in your basement" and that its interpretation has consequences. McCaskill said that Sotomayor is a nominee with "integrity, grit, intellect and the ability to pass judgment in the most difficult intellectual challenges that face a Supreme Court justice."According to "Political Intelligence," the floor speeches came after Klobuchar and others praised Sotomayor"s nomination at Monday"s annual convention of the left-leaning legal organization the American Constitution Society. In her speech, Klobuchar defended Sotomayor against conservative critics who have questioned the nominee"s temperament, citing complaints that Sotomayor was impatient with unprepared lawyers. Klobuchar said that she is "hoping that we would get to a point in this country where we could be appointing and confirming as many as rough and to-the-point female judges as we have appointed male judges" ("Political Intelligence," Boston Globe, 6/24).

The Downside Of Microtubule Stability - Study Shows Stalled Microtubules Might Be Responsible For Some Cases Of Charcot-Marie-Tooth Disease

Stalled microtubules might be responsible for some cases of the neurological disorder Charcot-Marie-Tooth (CMT) disease, Tanabe and Takei report in the June 15, 2009 issue of the Journal of Cell Biology. A mutant protein makes the microtubules too stable to perform their jobs, the researchers find. The mutations behind CMT disease slow nerve impulses, reduce their strength, or both. One of these mutations leads to production of faulty dynamin 2, a protein that is crucial for endocytosis but also latches onto microtubules. Tanabe and Takei investigated how defective dynamin 2 hampers cells. Normal microtubules are continually extending and shrinking. But microtubules from cells that made the faulty version of dynamin 2 were abnormally stable, as measured by how many acetyl groups were attached to them. The researchers also found that blocking normal dynamin 2 with RNAi had the same effect as the mutation, confirming that one of dynamin 2"s functions is to promote microtubule turnover. Removing dynamin 2 shattered the Golgi complex, Tanabe and Takei discovered. Dynamic microtubules help construct the Golgi complex in two ways: they capture the vesicles that combine to form a mature Golgi complex; and they provide a track along which these vesicles can travel to their rendezvous point near the nucleus. By breaking up the Golgi apparatus and then watching the fragments reunite, the researchers found that dynamin 2 was essential for the capture step, not for transportation. Dynamin 2 also clings to microtubules of the mitotic spindle, and the team next wants to determine whether the protein regulates microtuble dynamics during the cell cycle.
