About
Dr. Tom E. Porter is a Distinguished University Professor in the College of Agriculture and Natural Resources at the University of Maryland. His research focuses on the neuroendocrine regulation of growth and reproduction, cellular differentiation of the anterior pituitary gland during embryonic development, and the global analysis of gene expression in the neuroendocrine system. Dr. Porter has made significant contributions to the understanding of endocrine mechanisms in avian and animal physiology. He has authored over 113 refereed scientific papers, 23 book chapters or reviews, and 167 abstracts, with his publications cited more than 3,800 times. His work includes the submission of 35,452 nucleotide sequences to GenBank and five cDNA microarray platform submissions to GEO. Dr. Porter has received numerous awards, including the 2023 Distinguished University Professor title, the College of Agriculture and Natural Resources Faculty Research Award, and the Poultry Science Association Fellow designation. He has also served as the President and Vice President of the Poultry Science Association and as Editor-in-Chief for prominent scientific journals. His research has been supported by $29.6 million in federal grants, and he has mentored multiple postdoctoral fellows and graduate students.

Senior authorCorresponding, and triiodothyronine, while it increased mortality, glucose, pH, plasma thyroxine, and corticosterone. Expression of pituitary corticotropin-releasing hormone receptor 1 was downregulated (P < 0.001), while corticotropin-releasing hormone receptor 2 mRNA levels were higher (P = 0.001) in HS birds. HS increased expression of thyroid hormone receptor β (P = 0.01) (2.8-fold) and thyroid stimulating hormone β (P = 0.009) (1.4-fold). HS did not affect levels of mRNA of genes evaluated in the hypoth…
Characterization of the hypothalamo–pituitary–gonadal axis in low and high egg producing turkey hens
Poultry Science · 2020 · 34 citations
Variation in egg production exists in commercial turkey hens, with low egg producing hens (LEPH) costing more per egg produced than high egg producing hens (HEPH). Egg production correlates with ovulation frequency, which is governed by the hypothalamic-pituitary-gonadal (HPG) axis. Ovulation is stimulated by a preovulatory surge (PS) of progesterone and luteinizing hormone, triggered by gonadotropin releasing hormone release and inhibited by gonadotropin inhibiting hormone. Differences between…

articleOpen accessThe somatotropic axis influences growth and metabolism, and many of its effects are a result of insulin-like growth factor (IGF) signaling modulated by IGF-binding proteins (IGFBPs). Modern commercial meat-type (broiler) chickens exhibit rapid and efficient growth and muscle accretion resulting from decades of commercial genetic selection, and it is not known how alterations in the IGF system has contributed to these improvements. To determine the effect of commercial genetic selection on somato…

Senior authorCorrespondingBACKGROUND: The fasting-refeeding perturbation has been used extensively to reveal specific genes and metabolic pathways that control energy metabolism in the chicken. Most global transcriptional scans of the fasting-refeeding response in liver have focused on juvenile chickens that were 1, 2 or 4 weeks old. The present study was aimed at the immediate post-hatch period, in which newly-hatched chicks were subjected to fasting for 4, 24 or 48 h, then refed for 4, 24 or 48 h, and compared with a f…

articleOpen accessTargeted green light photostimulation during the last stage of broiler incubation increases expression of the somatotropic axis. The purpose of this study was to further shorten the in ovo green light photostimulation and determine the critical age for photostimulation in broilers embryos, as a future strategy for broiler incubation. Fertile broilers eggs (n = 420) were divided into 5 treatment groups. The first group was incubated under standard conditions (in the dark) as the negative control…
