Body fatness and physical activity at young ages and the risk of breast cancer in premenopausal women
(NATURE PUBLISHING GROUP, 2005-10-03)We examined the relationship between body fatness, sports participation and breast cancer risk in 1560 premenopausal cases and 1548 controls, from three related population-based case - control studies in the UK. Half of ... -
Chemotaxis towards hyaluronan is dependent on CD44 expression and modulated by cell type variation in CD44-hyaluronan binding.
(COMPANY OF BIOLOGISTS LTD, 2005-11-01)The accumulation of the extracellular matrix glycosaminoglycan hyaluronan by tumours and tumour-associated stroma promotes cancer cell invasion and metastasis. Using the Dunn chamber chemotaxis assay, we demonstrate for ... -
RNA editing of human microRNAs
(2006)BACKGROUND: MicroRNAs (miRNAs) are short RNAs of around 22 nucleotides that regulate gene expression. The primary transcripts of miRNAs contain double-stranded RNA and are therefore potential substrates for adenosine to ... -
Factors associated with emotional and behavioural problems among school age children of breast cancer patients
(2006-01-16)To identify factors linked with emotional and behavioural problems in school age (6- to 17-year-old) children of women with breast cancer. Reports of children’s emotional and behavioural problems were obtained from patient ... -
Synthesis of trisubstituted pyrimidines by regioselective S<sub>N</sub>Ar and Suzuki reactions of polyhalopyrimidines
(GEORG THIEME VERLAG KG, 2006-04-04)An efficient, regioselective approach to the synthesis of trisubstituted pyrimidines was developed. Sequential functionalization of com. available polyhalopyrimidines provided the target compds. in moderate to good overall ... -
Deficiency of LKB1 in heart prevents ischemia-mediated activation of AMPK alpha 2 but not AMPK alpha 1
(2006-05)Deficiency of LKB1 in heart prevents ischemia-mediated activation of AMPK alpha 2 but not AMPK alpha 1 Recent studies indicate that the LKB1 is a key regulator of the AMP-activated protein kinase ( AMPK), which plays a ... -
HPV testing in routine cervical screening: cross sectional data from the ARTISTIC trial
(NATURE PUBLISHING GROUP, 2006-07-03)To evaluate the effectiveness of human papillomavirus (HPV) testing in primary cervical screening. This was a cross-sectional study from the recruitment phase of a prospective randomised trial. Women were screened for HPV ... -
Recurrent KRAS Codon 146 mutations in human colorectal cancer
(2006-08)Recurrent KRAS Codon 146 mutations in human colorectal cancer An activating point mutation in codon 12 of the HRAS gene was the first somatic point mutation identified in a human cancer and established the role of somatic ... -
Signalling pathways implicated in early mammary gland morphogenesis and breast cancer.
(PUBLIC LIBRARY SCIENCE, 2006-08-01)Specification of mammary epithelial cell fate occurs during embryogenesis as cells aggregate to form the mammary anlage. Within the embryonic mammary bud, a population of epithelial cells exists that will subsequently ... -
Imaging of testicular germ cell tumours.
(E-MED LTD, 2006-09-07)In testicular germ cell tumour (GCT), imaging plays a central role in assessment of tumour bulk, sites of metastases, monitoring response to therapy, surgical planning and accurate assessment of disease at relapse. The ... -
Combinatorial effects of splice variants modulate function of Aiolos
(2007)The transcription factor Aiolos ( also known as IKZF3), a member of the Ikaros family of zinc-finger proteins, plays an important role in the control of B lymphocyte differentiation and proliferation. Previously, multiple ... -
Acetylation increases access of remodelling complexes to their nucleosome targets to enhance initiation of V(D)J recombination.
(2007-01)Targeted chromatin remodelling is essential for many nuclear processes, including the regulation of V(D)J recombination. ATP-dependent nucleosome remodelling complexes are important players in this process whose activity ... -

Stringent and reproducible tetracycline-regulated transgene expression by site-specific insertion at chromosomal loci with pre-characterised induction characteristics
(2007-01-01)Background: The ability to regulate transgene expression has many applications, mostly concerning the analysis of gene function. Desirable induction characteristics, such as low un-induced expression, high induced expression ... -
A phase I trial of the selective oral cyclin-dependent kinase inhibitor seliciclib (CYC202; R-Roscovitine), administered twice daily for 7 days every 21 days.
(NATURE PUBLISHING GROUP, 2007-01-15)Seliciclib (CYC202; R-roscovitine) is the first selective, orally bioavailable inhibitor of cyclin-dependent kinases 1, 2, 7 and 9 to enter clinical trial. Preclinical studies showed antitumour activity in a broad range ... -
Calculation of x-ray spectra emerging from an x-ray tube. Part I. electron penetration characteristics in x-ray targets.
(WILEY, 2007-06-01)The penetration characteristics of electron beams into x-ray targets are investigated for incident electron kinetic energies in the range 50-150 keV. The frequency densities of electrons penetrating to a depth x in a target, ... -
Meis1 is an essential and rate-limiting regulator of MLL leukemia stem cell potential
(COLD SPRING HARBOR LAB PRESS, PUBLICATIONS DEPT, 2007-11-01)Oncogenic mutations of the MLL histone methyltransferase confer an unusual ability to transform non-self-renewing myeloid progenitors into leukemia stem cells (LSCs) by mechanisms that remain poorly defined. Misregulation ... -
