Study of placenta unexpectedly leads to cancer gene

University of Rochester Medical Center scientists discovered a gene mutation that impairs the placenta and also is influential in cancer development, according to a study published online December 16, 2008, in the journal PLoS (Public Library of Science) Biology.

Tracking the molecular pathway to mixed-lineage leukemia

Infants and adults with the blood cancer mixed-lineage leukemia (MLL) typically have a poor prognosis, and most infants die before their first birthdays.

Researchers stop ovarian cancer cell cycle in its tracks

Ovarian cancer cells are "addicted" to a family of proteins produced by the notorious oncogene, MYC, and blocking these Myc proteins halts cell proliferation in the deadliest cancer of the female reproductive system, according to a presentation by University of California, Berkeley scientists at the American Society for Cell Biology (ASCB) 48th Annual Meeting, Dec. 13-17, 2008 in San Francisco.

Researchers simplify creation induced pluripotent stem (iPS) cells

Bryce Carey, an MIT graduate student working in the lab of Whitehead Member Rudolf Jaenisch, spearheaded the effort by joining in tandem the four reprogramming genes through the use of bits of DNA that code for polymers known as 2A peptides. Working with others in the lab, he then manufactured a so-called polycistronic virus capable of expressing all four reprogramming genes once it is inserted into the genomes of mature mouse and human cells.

New imaging technique allows simultaneous tracking of gene expression and movement

Flies expressing green fluorescent protein (GFP) in their retina cells or other tissues can be tracked by specially modified video cameras, creating a real time computer record of movement and gene expression.

New insight into birth defect synpolydactyly

Birth defects characterized by malformation of the limbs are relatively common.

Discovery of new genetic cause severe combined immunodeficiency (SCID)

Severe combined immunodeficiency (SCID) is an inherited disease sometimes known as 'Boy in the bubble syndrome', because the patient lacks one or more type of immune cell, making them very susceptible to infections.

11 new genes linked to LDL, HDL cholesterols and triglycerides

A new study uncovers 11 gene variants associated with three blood lipids measured to determine cardiovascular disease risk: low-density lipoprotein (LDL) cholesterol, high-density lipoprotein (HDL) and triglycerides.

Gene subnetworks provide new prognostic markers for breast cancer

The metastasis or spread of breast cancer to other tissues in the body can be predicted more accurately by examining subnetworks of gene expression patterns in a patient's tumor, than by conventional gene expression microarrays, according to a presentation at the American Society for Cell Biology (ASCB) 48th Annual Meeting, Dec. 13-17, 2008 in San Francisco.

How to build muscle mass with four and a half LIM domains 1

Mutations in FHL1 are present in several myopathies, including reducing-body myopathy (RBM), but until now, both the molecular mechanisms causing the disease, and the regular function of FHL1 in healthy tissue, remained unknown.

Fruits, vegetables and fiber may cut risk of breast cancer recurrence in women without hot flashes

A secondary analysis of a large, multicenter clinical trial has shown that a diet loaded with fruits, vegetables and fiber and somewhat lower in fat compared to standard federal dietary recommendations cuts the risk of recurrence in a subgroup of early-stage breast cancer survivors - women who didn't have hot flashes - by approximately 31 percent.

Blocking Myc proteins stops ovarian cancer cell cycle in its tracks

Ovarian cancer cells are "addicted" to a family of proteins produced by the notorious oncogene, MYC.

Mechanism behind cardiac scarring discovered

In the aftermath of a heart attack, the body's own defenses may contribute to future heart failure. Authors of a new study believe they have identified a protein that plays an important role in a process that replaces dead heart muscle with stiffening scar tissue. The researchers are hopeful that the findings will lead to the development of new therapies to prevent this damage.

Mouse model shows blood stem cells in action

Over a period of five years, scientists at the Johannes Gutenberg University Mainz have managed to create a genetically modified mouse in which the activity of the blood stem cells can be tracked.

Fatherhood gene determines if it's a boy or a girl

According to recent research whether men are likely to father a boy or a girl is determined by a "fatherhood gene".

GUMC researchers find gene inactivated in two aggressive cancers

Researchers at Georgetown University Medical Center have found a gene they say is inactivated in two aggressive cancers - malignant melanoma, a form of skin cancer, and glioblastoma multiforme, a lethal brain tumor.

Three studies of bioTheranostics molecular breast cancer diagnostics presented at symposium

bioTheranostics, a bioMerieux company that discovers, develops and commercializes new molecular diagnostic tests in oncology, reported today findings from three studies using the company's molecular breast cancer assay to predict risk of disease recurrence in individual patients.

Promising clinical trial for Progeria "premature aging" disease

One of the fastest translations of a basic research discovery into a promising clinical trial for an "untreatable" and fatal disorder will be discussed publicly for the first time by the key players in this remarkable research story, on Sunday, Dec. 14, at the American Society for Cell Biology (ASCB)'s annual meeting in San Francisco.
