A Sertoli cell-selective knockout of the androgen receptor causes spermatogenic arrest in meiosis

…, M Dewerchin, A Devos, K Tan… - Proceedings of the …, 2004 - National Acad Sciences
Androgens control spermatogenesis, but germ cells themselves do not express a functional
androgen receptor (AR). Androgen regulation is thought to be mediated by Sertoli and …

Prevalence of melanocortin-4 receptor deficiency in Europeans and their age-dependent penetrance in multigenerational pedigrees

F Stutzmann, K Tan, V Vatin, C Dina, B Jouret… - Diabetes, 2008 - Am Diabetes Assoc
OBJECTIVE— Melanocortin-4 receptor (MC4R) deficiency is the most frequent genetic
cause of obesity. However, there is uncertainty regarding the degree of penetrance of this …

The role of androgens in Sertoli cell proliferation and functional maturation: studies in mice with total or Sertoli cell-selective ablation of the androgen receptor

KAL Tan, K De Gendt, N Atanassova, M Walker… - …, 2005 - academic.oup.com
The role of androgens in the proliferation and maturation of Sertoli cells (SC) and the
development of their capacity to support spermatogenesis remains poorly understood. We …

Serrate1-induced Notch signalling regulates the decision between immunity and tolerance made by peripheral CD4+ T cells

…, I Le Roux, M Corsin-Jimenez, K Tan… - International …, 2000 - academic.oup.com
Signals derived from antigen-presenting cells (APC) influence the functional differentiation
of CD4 + T cells. We report here that Serrate1 (Jagged1), a ligand for the Notch1 receptor, …

[HTML][HTML] MAP-1, a novel proapoptotic protein containing a BH3-like motif that associates with Bax through its Bcl-2 homology domains

KO Tan, KML Tan, SL Chan, KSY Yee, M Bévort… - Journal of Biological …, 2001 - ASBMB
A novel Bax-associating protein, named MAP-1 (Modulator of Apoptosis), has been identified
in a yeast two-hybrid screen. MAP-1 contains a BH3-like (BH:Bcl-2 homology) motif and …

[BOOK][B] Clean, green and blue: Singapore's journey towards environmental and water sustainability

YS Tan, TJ Lee, K Tan - 2009 - books.google.com
When Singapore became a sovereign state in 1965, the fledgling nation faced very similar
problems as most other developing countries: high unemployment, low standard of living, and …

The effect of a Sertoli cell-selective knockout of the androgen receptor on testicular gene expression in prepubertal mice

…, K Marchal, P Van Hummelen, KAL Tan… - Molecular …, 2006 - academic.oup.com
To unravel the molecular mechanisms mediating the effects of androgens on spermatogenesis,
testicular gene expression was compared in mice with Sertoli cell-selective androgen …

A quantitative trait locus on chromosome 18q for physical activity and dietary intake in Hispanic children

G Cai, SA Cole, N Butte, C Bacino, V Diego, K Tan… - …, 2006 - Wiley Online Library
Objective: Genetic components of energy homeostasis contributing to childhood obesity are
poorly understood. Genome scans were performed to identify chromosomal regions …

[HTML][HTML] Comparative gene expression profiling identifies common molecular signatures of NF-κB activation in canine and human diffuse large B cell lymphoma …

…, RD Haggart, G Miele, G Sellar, KAL Tan… - PloS one, 2013 - journals.plos.org
We present the first comparison of global transcriptional changes in canine and human diffuse
large B-cell lymphoma (DLBCL), with particular reference to the nuclear factor-kappa B (…
