First step in development of artificial human testicle

After more than 30 years of unsuccessful efforts by numerous investigators, researchers have now found a way to propagate primary human Sertoli cells in the laboratory. Derived from the testis, it has been difficult to maintain Sertoli cells, the "nurse" cells responsible for overseeing sperm production, outside of the human body.

Researchers find gene mutation mechanism that cause mitochondrial diseases

Scientists have discovered a new cause of spastic ataxia, and believe this cause is also a trigger for other mitochondrial diseases neurological disorders that can lead to serious coordination, growth, visual, speech, and muscle defects.

Mirna announces USPTO allows claims to therapeutic application of let-7 miRNA

Mirna Therapeutics, Inc. announced today that the USPTO has allowed claims related to the therapeutic application of let-7 in the regulation of oncogenes. The claims derive from a patent application that was submitted by Yale University and exclusively licensed to Mirna related to the pioneering work of Dr. Frank Slack, Professor of Molecular, Cellular & Developmental Biology at Yale University in New Haven, CT.

Scientists unveil quality control mechanism of immune system to destroy pathogens

An Australian team of scientists has uncovered a quality control mechanism that must take place for our immune system to subsequently effectively destroy harmful viruses and bacteria.

Researchers find exposure to air pollution increases severity of asthma symptoms

Exposure to dirty air is linked to decreased function of a gene that appears to increase the severity of asthma in children, according to a joint study by researchers at Stanford University and the University of California, Berkeley.

Cell aging is associated with reduced histone level

Like cats, human cells have a finite number of lives-once they divide a certain number of times they change shape, slow their pace, and eventually stop dividing, a phenomenon called cellular senescence.

Researchers discover new factors that regulate fat formation

By creating a "map" of histone modifications in fat cells, investigators have discovered two new factors that regulate fat formation, a key step on the road to better understanding obesity, diabetes and other metabolic disorders.

Researchers discover new signaling pathway for cell development

Researchers at UCLA's Jonsson Comprehensive Cancer Center have discovered a new cell signaling pathway that controls cell growth and development, a pathway that, when defective, helps promote the formation of several major forms of human cancer, including lymphoma and leukemia.

Researchers identify protein essential for dendritic cell development

A protein called PU.1 is essential for the development of dendritic cells, the sentinels of the immune system, Walter and Eliza Hall Institute researchers in Melbourne, Australia, have shown.

Research on signaling pathways may help to design therapy for neurodevelopmental disorders

Researchers at the Center for Neuroscience Research at Children's National Medical Center have discovered that the two major types of signaling pathways activated during brain cell development-the epidermal growth factor receptor pathway and the Notch pathway-operate together to determine how many and which types of brain cells are created during growth and repair in developing and adult brains.

Human cytomegalovirus cloned

A team of Welsh scientists have successfully cloned a human virus offering new hope for the treatment of potentially life-threatening diseases.

Scientists suggest aggressive forms of breast cancer develops from intermediary cells

A UK research team has taken an important step forward in improving our understanding of the origins of breast cancer. Scientists at the Breakthrough Breast Cancer Research Centre at The Institute of Cancer Research (ICR) in London have found evidence suggesting that aggressive forms of breast cancer are likely to develop from intermediary slightly more developed cells, rather than from stem cells.

Advanced Life Sciences scientific publication demonstrates triterpenoids' potential as anticancer agents

Advanced Life Sciences Holdings, Inc.,a biopharmaceutical company engaged in the discovery, development and commercialization of novel drugs in the therapeutic areas of infection, oncology and respiratory diseases, today announced the publication of a research paper in the journal Bioorganic and Medicinal Chemistry Letters that reports data using the Company's core triterpenoid platform technology in the discovery and development of new cancer therapeutic agents.

Study results provide rationale for use of PI3K inhibitors in therapeutic settings

Research at the Babraham Institute, investigating how white blood cells known as B cells develop, has revealed that genes from the Phosphatidylinositol 3-kinase family of enzymes are critical in enabling the B cells to produce antibodies in the spleen and lymph nodes.

UCSF researchers discover new technology purifying special types of stem cells

UCSF researchers are reporting the first success in very rapidly purifying one type of embryonic stem cell from a mix of many different types of embryonic stem cells in the culture dish. The technique, which avoids the need to genetically alter the cells to distinguish them, is a key advance, the researchers say, for obtaining the appropriate cells for repairing specific damaged tissues.

UC Riverside scientists secure grants for tobacco control research

Tobacco-related disease kills more people worldwide than any other single factor. To help address this problem, the University of California, Riverside has received six grants from the University of California Tobacco-Related Disease Research Program (TRDRP), the most TRDRP grants the campus has received in any year.

Ferroportin levels are strong predictors of propensity for breast cancer recurrence: Study

A new study by researchers at Wake Forest University Baptist Medical Center (WFUBMC) may soon help to spare some women with breast cancer from having to undergo invasive and toxic treatments for their disease.

Study to understand processes that lead to onset of testicular germ cell cancer

Scientists have developed a model that will enable them to investigate, for the first time, how human testes develop in baby boys while they are in the womb. Until now it has been impossible to study testicular development during pregnancy in humans and this discovery will enable researchers to understand the processes that can lead to the onset of testicular germ cell cancer (TGCC) in young adult life, and how factors, such as common environmental chemicals, might play a role.

microRNA protects red blood cells from oxidant stress: Study

Pediatric researchers have discovered a new biological pathway in which small segments of RNA, called microRNA, help protect red blood cells from injury caused by chemicals called free radicals. The microRNA seems to have only a modest role when red blood cells experience normal conditions, but steps into action when the cells are threatened by oxidant stress.

Researchers discover tumor suppressor lincRNAs

The recent discovery of more than a thousand genes known as large intergenic non-coding RNAs (or "lincRNAs") opened up a new approach to understanding the function and organization of the genome. That surprising breakthrough is now made even more compelling with the finding that dozens of these lincRNAs are induced by p53 (the most commonly mutated gene in cancer), suggesting that this class of genes plays a critical role in cell development and regulation. Furthermore, the researchers identify one lincRNA in particular (lincRNA-p21), and demonstrate its critical role in suppressing the reading of many genes across the genome following p53 activation.
