Thyroid hormones (TH) are important for the development of the human fetus and placenta from very early gestation. The transplacental passage of TH from mother to fetus and the supply of TH into trophoblasts require the expression of placental TH plasma membrane transporters. We describe the ontogeny of the TH transporters MCT8, MCT10, LAT1, LAT2, OATP1A2(More)
Thyroid hormones (THs) are essential for normal fetal development, with even mild perturbation in maternal thyroid status in early pregnancy being associated with neurodevelopmental delay in children. Transplacental transfer of maternal THs is critical, with increasing evidence suggesting a role for 3,3',5-tri-iodothyronine (T3) in development and function(More)
Associations of neurological impairment with mutations in the thyroid hormone (TH) transporter, MCT8, and with maternal hypothyroxinaemia, suggest that THs are crucial for human fetal brain development. It has been postulated that TH transporters regulate the cellular supply of THs within the fetal brain during development. This study describes the(More)
Cystinuria is a recessively inherited aminoaciduria that leads to recurrent urolithiasis. It is caused by the defective transport of cystine and dibasic amino acids in the proximal renal tubules and intestinal epithelium. Two genes responsible for this, SLC3A1 and SLC7A9, are known. Patients with two SLC3A1 mutations are classified as type A cystinuria,(More)
Androgen deficiency in the ageing male (ADAM) was proposed to characterize a symptom cluster of decrease in sexual function and strength, dysphoria and osteopenia in ageing men with decreased levels of androgens. Unlike menopause, literature on the topic is scarce and focuses mainly on the physiological aspects of the problem. However, men with ADAM also(More)
We have described the expression of specific iodothyronine deiodinase mRNAs (using quantitative RT-PCR) and activities in normal human placentas throughout gestation and compared our findings to those in placentas from pregnancies affected by intrauterine growth restriction (IUGR). The predominant deiodinase expressed in placenta was type III (D3); type II(More)
UNLABELLED Term 'villous' placenta consists of a heterogeneous mix of different cell types comprising the trophoblast layers, villous stroma and fetal blood vessels. The importance of using techniques which allow investigation of pure populations of cells has been increasingly recognised. We demonstrate the use of laser capture microdissection (LCM) in(More)
