Whole-organ genomic survey depicts journey from normal to malignant cell

Whole-organ maps that superimpose genetic information over the terrain of cancerous bladders chart the molecular journey from normal cell to invasive cancer, an international research team led by scientists at The University of Texas M. D. Anderson Cancer Center reports online at the journal Laboratory Investigation.

New understanding of colon tumor development

Recent work from the Finnish Academy Center of Excellence on Cancer Biology at the University of Helsinki, Finland, has shed light on the mechanisms of colon tumor development and may help to design better treatment for this disease.

Alendronate may improve successful implantation of maxillary bone

A new study has established that estrogen deficiency negatively affects implant osseointegration in rats' maxillary bone.

Biomarker predicts malignancy potential of HG-PIN lesions in the prostate

Men whose prostate cancer screenings show high grade prostatic intraepithelial neoplasia (HG-PIN) may find themselves in limbo, "stuck" between diagnoses - they are told prostate cancer has not yet developed, but it might, and they are advised to undergo repeated needle biopsies as a precaution.

Mothers and offspring can share cells throughout life - with positive and negative effects

Cutting the umbilical cord doesn't necessarily sever the physical link between mother and child. Many cells pass back and forth between the mother and fetus during pregnancy and can be detected in the tissues and organs of both even decades later. This mixing of cells from two genetically distinct individuals is called microchimerism. The phenomenon is the focus of an increasing number of scientists who wonder what role these cells play in the body.

Brain tumor surgery, depression and survival

Depression is one of the most common psychiatric disorders in the world today. It is estimated that in any given year, 5 to 9 percent of the US population is clinically depressed. Studies have shown that depression negatively affects the immunological system, alters the body's response to malignancy, and may influence behavioral factors that impact recovery from disease

Pralatrexate for T-cell lymphoma

The fifth leading cause of cancer in the United States, lymphoma is made up of more than 40 rare and highly diverse diseases that target the body's lymphatic system. Lymphomas include both one of the fastest growing cancers -- Burkitt's lymphoma, which can double in size in as little as a day -- and one of the slowest, chronic lymphocytic leukemia (CLL).

AMPK signaling helps explain how cell growth is inhibited when nutrients are low

A team of scientists at the Salk Institute for Biological Studies think they know how many-if not most-living organisms answer this question. They recently showed that when food supplies dwindle, mammals, fruitflies, or frogs probably activate the same ancient cell signaling pathway in order to conserve energy.

Scientists determine molecular structures of bacterial AlkB protein and its corresponding human protein, ABH2

A team of University of Chicago scientists has shown how two proteins locate and repair damaged genetic material inside cells.

MacroChem acquires Virium Pharmaceuticals

MacroChem Corporation announced today that on April 18, 2008 it acquired Virium Pharmaceuticals Inc., a non-public, development stage company developing and commercializing novel therapeutics, with a portfolio of clinical stage product candidates focused in oncology, including its next generation nucleoside analogue licensed from the Southern Research Institute.

New advance in use of oncolytic viruses as novel cancer treatments

Combining a herpes virus genetically altered to express a drug-enhancing enzyme with a chemotherapy drug effectively and safely reduced the size of highly malignant human sarcoma grafted into mice.

Lorus initiates development program exploring novel route of administration for LOR-2040

Lorus Therapeutics Inc. today announced the start of a development program aimed at expanding the therapeutic application of its lead clinical-stage drug LOR-2040 for the treatment of superficial bladder cancer.

Cancer could return unless stored ovarian tissue undergoes adequate testing before re-implantation

Cancer patients who have been successfully treated for their disease face the prospect of its return if stored ovarian (or testicular) tissue is transplanted back into their bodies without adequate checks, according to researchers at two university hospitals in Israel.

Scalp or neck melanomas most dangerous

People with scalp or neck melanomas die at nearly twice the rate of people with melanoma elsewhere on the body, including the face or ears, researchers at the University of North Carolina at Chapel Hill have found.

Discovery of fundamental mechanism of how tumour cells communicate

A new fundamental mechanism of how tumour cells communicate has just been discovered by the team of Dr. Janusz Rak at the Research Institute of the McGill University Health Centre (MUHC) in collaboration with Dr Guha from the University of Toronto.

Nanomagnets used to carry genes to fight tumours

A revolutionary cancer treatment using microscopic magnets to enable 'armed' human cells to target tumours has been developed by researchers funded by the Biotechnology and Biological Sciences Research Council (BBSRC).

New type of drug shrinks primary breast cancer tumours significantly in just six weeks

A drug that targets the cell surface receptors that play an important role in many types of cancer can bring about significant tumour regression in breast cancer after only six weeks of use, a scientist told the 6th European Breast Cancer Conference (EBCC-6) (Thursday 17 April).
