Scientists wrestle to understand why Huntington's can produce variable symptoms

Scientists have wrestled to understand why Huntington's disease, which is caused by a single gene mutation, can produce such variable symptoms. An authoritative review by a group of leading experts summarizes the progress relating cell loss in the striatum and cerebral cortex to symptom profile in Huntington's disease, suggesting a possible direction for developing targeted therapies.

Fluoxetine stimulates production of new neurons from L1-INP cells

The production of new neurons in the adult normal cortex in response to the antidepressant, fluoxetine, is reported in a study published online this week in Neuropsychopharmacology.

Study investigates prolonged pathological outcomes of traumatic brain injury

Researchers from the University of South Florida and colleagues at the James A. Haley Veterans' Hospital studying the long-term consequences of traumatic brain injury using rat models, have found that, overtime, TBI results in progressive brain deterioration characterized by elevated inflammation and suppressed cell regeneration.

Calphotin essential in keeping cellular calcium concentration low

All living cells keep their cellular calcium concentration at a very low level. Since a small increase in calcium can affect many critical cellular functions (an elevated calcium concentration over an extended period can induce cell death), powerful cellular mechanisms ensure that calcium concentration quickly returns to its low level.

Researchers reveal critical role of BRCA1 gene in maintenance of hair follicle stem cells

Our DNA, which stores our genetic information, is constantly submitted to damage. If not properly repaired, DNA damage can lead to cell death, which may in turn lead to tissue exhaustion and ageing, or induce mutations resulting in uncontrolled cell proliferation and cancer. Brca1 is a key gene that mediates DNA repair. Mutations in Brca1 lead to familial and sporadic breast and ovarian cancer in humans.

Iron oxide nanoparticles could help track transplanted human endothelial cells

A team of researchers from three medical institutions in Guangzhou, China, have found that iron oxide nanoparticles (INOPS) are a useful contrast agent for in vivo magnetic resonance tracking of transplanted human endothelial cells.

New work on Akt's role in cancer stem cell biology

The protein kinase Akt is a key regulator of cell growth, proliferation, metabolism, survival, and death. New work on Akt's role in cancer stem cell biology from the lab of senior author Honglin Zhou, MD, PhD and Weihua Li, co-first author, both from the Center for Resuscitation Sciences, Department of Emergency Medicine, Perelman School of Medicine, University of Pennsylvania, and Xiaowei Xu, Department of Pathology and Laboratory Medicine, appears in Molecular Cell.

Tumor cells manipulate unfolded protein response

Researchers at the University of California, San Diego School of Medicine report that tumor cells use stress signals to subvert responding immune cells, exploiting them to actually boost conditions beneficial to cancer growth.

Budding yeast an acceptable model system to study KP1019 anti-cancer drug

Researchers have found that the budding yeast (Saccharomyces cerevisiae) is an acceptable model system to study KP1019, an anti-cancer drug that uses ruthenium, a rare metal, a new study found. Researchers had previously been interested in studying KP1019 because it is believed to cause cancer cell death and is not known to have negative secondary side effects for healthy tissues.

MiR-181 molecule tied to breast cancer metastasis

Researchers at Case Western Reserve University School of Medicine have identified a molecule linked to more aggressive forms of breast cancer - a discovery that could point the way to potential cures.

Researchers identify 125 genetic components in temozolomide-resistant, GBM-derived cell line

University of Pittsburgh Cancer Institute (UPCI) researchers have identified over 125 genetic components in a chemotherapy-resistant, brain tumor-derived cell line, which could offer new hope for drug treatment to destroy the cancer cells.

Study describes new, paradoxical characteristics of HER2-negative breast cancer

A multicenter study led by researchers at UC Davis describes new, paradoxical characteristics of the most common type of breast cancer. The findings shed light on how the disease can evade treatment and could improve diagnosis and treatment of breast cancer.

Ibrutinib continues to show unprecedented results in patients with mantle cell lymphoma

An international study of ibrutinib in people with relapsed or refractory mantle cell lymphoma (MCL) continues to show unprecedented and durable results with few side effects.

Scientists discover how Yersinia pestis avoids setting off immune system's early infection-alarm

The plague-causing bacteria Yersinia pestis evades detection and establishes a stronghold without setting off the body's early alarms.

Administration of N2O + ISO appears to have negative effect on fetal development

An anesthetic regimen typically used during surgery on pregnant mothers appears to have a negative effect on the development of the fetus, according to a new study on mice conducted by neurobiologists from the National Center for Toxicological Research, in Arizona.
