Abstract
ABSTRACTProtein deficiency, characterized by an inadequate intake of protein in the diet that fails to meet the body's physiological requirements across various stages, can lead to detrimental outcomes. This is of interest due to the persistent low protein content in staple foods and suboptimal dietary patterns. The study sought to assess the intergenerational repercussions of dietary protein deficiency on specific neurochemicals and the cytoarchitecture of the brain within the F1 and F2 generations of rats. The rats were categorized into four groups based on the protein content percentage in their diets: 21% protein diet (21%PD), 10% protein diet (10%PD), 5% protein diet (5%PD), and control diet. Neurobehavior was assessed, while brain serotonin and dopamine levels were measured using HPLC. BDNF and GDNF expression in the hippocampal and prefrontal (PFC) sections, Immunohistochemical investigations of the morphological impact on the hippocampus and PFC, were also analyzed. The protein-deficient groups displayed anxiety, loss of striatal serotonin and increased dopamine levels, degenerated pyramidal cells in the hippocampus, and a prominent reduction in cellular density in the PFC. BDNF and GDNF levels in the PFC were reduced in the 5%PD group. GFAP astrocyte expression was observed to be increased in the prefrontal cortex (PFC) and hippocampal sections, indicating heightened reactivity. The density of hypertrophied cells across generations further suggests the presence of neuroinflammation. Changes in brain structure, neurotransmitter levels, and neurotrophic factor levels may indicate intergenerational alterations in critical regions, potentially serving as indicators of the brain's adaptive response to address protein deficiency across successive generations.

Association of Maternal Mild Hypothyroidism With Offspring Neurodevelopment in TPOAb-Negative Women: A Prospective Cohort Study. Front Endocrinol (Lausanne) 2022; 13:884851.

Abstract
OBJECTIVES Adequate maternal thyroid hormone availability is crucial for fetal neurodevelopment, but the role of maternal mild hypothyroidism is not clear. We aim to investigate the association of maternal mild hypothyroidism with neurodevelopment in infants at 1 year of age among TPOAb-negative women. METHODS The present study was conducted within the Jiangsu Birth Cohort. A total of 793 mother-infant pairs were eligible for the present study. Maternal thyroid function was assessed by measuring serum thyroid-stimulating hormone, free thyroxine, and thyroid peroxidase antibodies. Neurodevelopment of infants was assessed by using the Bayley Scales of Infant and Toddler Development third edition screening test (Bayley-III screening test). RESULTS In the multivariate adjusted linear regression analyses, infants of women with subclinical hypothyroidism and isolated hypothyroxinemia were associated with decreased receptive communication scores (β = -0.68, p = 0.034) and decreased gross motor scores (β = -0.83, p = 0.008), respectively. Moreover, infants of women with high-normal TSH concentrations (3.0-4.0 mIU/L) and low FT4 concentrations were significantly associated with lower gross motor scores (β = -1.19, p = 0.032), while no differences were observed in infants when the mothers had a high-normal TSH concentration and normal FT4 levels. CONCLUSIONS Maternal subclinical hypothyroidism is associated with decreased receptive communication scores in infants at 1 year of age. In addition, maternal TSH concentration greater than 4.0 mIU/L and maternal isolated hypothyroxinemia are associated with impaired gross motor ability of infants, especially in infants of women with high-normal TSH concentrations (3.0-4.0 mIU/L).
