Incidence of potentially life-threatening diabetes complication increasing among youth in Colorado

The incidence of a potentially life-threatening complication of diabetes, diabetic ketoacidosis, in youth in Colorado at the time of diagnosis of type 1 diabetes increased by 55 percent between 1998 and 2012, suggesting a growing number of youth may experience delays in diagnosis and treatment, according to a study in the April 21 issue of JAMA, a theme issue on child health.

Novel treatment strategy targets treatment-resistant CML

Researchers have shown that the coiled-coil mimetic CCmut3 can inhibit cell growth and promote apoptosis in cell lines expressing BCR–ABL1, including those resistant to tyrosine kinase inhibitors.

Ibrutinib (IMBRUVICA) may be effective for pancreatic ductal adenocarcinoma

Ibrutinib (IMBRUVICA) data presented yesterday by Pharmacyclics, Inc. at the American Association for Cancer Research Annual Meeting suggest that ibrutinib may be an effective therapeutic option for pancreatic ductal adenocarcinoma (PDAC), as shown in both a transgenic mouse model and an in-vivo model of patient-derived xenograft (PDX) mice (grafts of tissue taken from a pancreatic cancer patient and grafted into a mouse).

Scientists discover protein that boosts immunity to viruses and cancer

Experiments in mice and human cells have shown that the protein promotes the proliferation of cytotoxic T cells, which kill cancer cells and cells infected with viruses...

Zinc deficiency can activate Hedgehog signaling pathway

Zinc deficiency - long associated with numerous diseases, e.g. autism, lung cancer, prostate cancer, and ovarian cancers - can lead to activation of the Hedgehog signaling pathway, a biomolecular pathway that plays essential roles in developing organisms and in diseases, according to new research at Rensselaer Polytechnic Institute.

New research links megalin protein with malignant melanomas

Today it is not possible to predict spreading from malignant melanomas. Melanoma metastases are furthermore extremely difficult to eliminate as traditional treatment such as chemotherapy and radiotherapy is mostly ineffective. Only ten per cent of the patients survive once they reach an advanced stage with distant metastases.

UC Davis researchers unravel how micro RNA could potentially lead to novel cancer therapies

The micro RNA miR-22 has long been known for its ability to suppress cancer. However, questions remain about how it achieves this feat. For example, which molecules are regulating miR-22, and which are miR22 targets?

Nanomedicine strategy can help reduce heart attacks, strokes

A research team showed that a nanotherapeutic medicine can halt the growth of artery plaque cells resulting in the fast reduction of the inflammation that may cause a heart attack, according to a study led by researchers from Icahn School of Medicine at Mount Sinai and published April 3 in Science Advances.

Online resources can improve the practice of emergency medicine

Two new studies, published online Tuesday in Annals of Emergency Medicine, illustrate the power of social media and the Internet to promote scholarly dialogue around the world and the importance of establishing criteria for what constitutes high-quality blogs and podcasts ("Global Emergency Medicine Journal Club: A Social Media Discussion About the ADJUST-PE Trial" and "Emergency Medicine and Critical Care Blogs and Podcasts: Establishing an International Consensus on Quality").

Leukemia drug could prevent and control growth of colorectal tumours

Scientists from Nanyang Technological University (NTU Singapore) and Sweden's Karolinska Institutet, one of Europe's largest and most prestigious medical universities, have discovered that an existing chemotherapy drug used to treat leukaemia could prevent and control the growth of colorectal tumours.

Pseudogenes may play role in cancer development, shows study

Pseudogenes, a sub-class of long non-coding RNA (lncRNA) that developed from the genome's 20,000 protein-coding genes but lost the ability to produce proteins, have long been considered nothing more than genomic "junk." Yet the retention of these 20,000 mysterious remnants during evolution has suggested that they may in fact possess biological functions and contribute to the development of disease.

Researchers pinpoint molecular mechanisms that inhibit Hippo pathway in pediatric bone cancers

A particular molecular pathway permits stem cells in pediatric bone cancers to grow rapidly and aggressively, according to researchers at NYU Langone Medical Center and its Laura and Isaac Perlmutter Cancer Center.

Researchers uncover relationship between two proteins linked to cerebral cavernous malformations

Researchers have uncovered new details about the relationship between two proteins associated with the formation of cerebral cavernous malformations, a little understood neurovascular disorder.

Experimental nanoparticle therapy speeds healing of all sorts of wounds

An experimental therapy developed by researchers at Albert Einstein College of Medicine of Yeshiva University cut in half the time it takes to heal wounds compared to no treatment at all. Details of the therapy, which was successfully tested in mice, were published online in the Journal of Investigative Dermatology.

TSRI scientists identify enzyme that maintains healthy periods of inactivity in HSCs to prevent anemia

Stem cells can generate any type of cell in the body, but they are inactive most of the time—and for good reason. When stem cells become too active and divide too often, they risk acquiring cell damage and mutations. In the case of blood stem cells (also called hematopoietic stem cells or HSCs), this can lead to blood cancers, a loss of blood cells and an impaired ability to fight disease.

ItpkB enzyme regulates stem cells function to prevent cancer, anemia

Stem cells can generate any type of cell in the body, but they are inactive most of the time--and for good reason. When stem cells become too active and divide too often, they risk acquiring cell damage and mutations.

Vitamin D3 and metformin show promising results in preventing colorectal cancer

The concept was simple: If two compounds each individually show promise in preventing colon cancer, surely it's worth trying the two together to see if even greater impact is possible.

Discovery may lead to new potential treatment for drug-resistant melanoma

In the last several years, targeted therapies - drugs that directly impact specific genes and proteins involved in the progression of cancer - have been approved for a wide variety of cancers, including melanoma, the deadliest form of skin cancer. Now, researchers at The Wistar Institute have discovered one way in which melanoma becomes resistant to a particular form of targeted therapy, and understanding this phenomenon may lead to a new melanoma target or prompt new designs of these treatments.

MED15 may serve as prognostic marker for HNSCC recurrence

A new study provides the first evidence that the mediator complex subunit 15 (MED15) may play a crucial role in the pathophysiology of head and neck squamous cell carcinoma (HNSCC). MED15 overexpression was found to be associated with higher mortality rates in HNSCC patients with cancer recurrence, particularly in oral cavity/oropharyngeal tumors, according to the study published in The American Journal of Pathology.

New approach to improve cardiac regeneration

The heart tissue of mammals has limited capacity to regenerate after an injury such as a heart attack, in part due to the inability to reactivate a cardiac muscle cell and proliferation program. Recent studies have indicated a low level of cardiac muscle cell (cardiomyocytes) proliferation in adult mammals, but it is insufficient to repair damaged hearts.
