Abstract
Objective: Migraine attacks are common in women of reproductive age. Although attacks are often less severe and less frequent during pregnancy, they regularly reoccur shortly after delivery. When first-line analgesic treatment is insufficient, triptans may be used for acute treatment of migraine attacks. Milk levels of occasional triptan use have shown to be low, and no adverse effects in breastfed infants have been reported. However, the available knowledge on the safety of triptans during breastfeeding is still limited. Methods: Four (inter)national pharmacovigilance databases were searched for breastfeeding related adverse drug reactions of triptans. These included the Dutch Pregnancy Drug Register and three databases of spontaneous reports (Netherlands Pharmacovigilance Centre Lareb, the European Medicines Agency [EudraVigilance], and the World Health Organization [VigiBase]). Results: A total of 26 reports on 27 breastfeeding related adverse drug reactions were identified (one report involved two separate adverse drug reactions). These involve three main complaints: painful breasts and/or nipples, painful milk ejection reflex, and a decrease in milk production. Discussion and Conclusion: The hypothesized pharmacological mechanism relates to the serotonin-receptor agonistic properties of triptans. These may lead to vasoconstriction in the breasts and nipples, including the vasculature surrounding the milk ducts and alveoli, and may also influence the hormonal function and levels of prolactin. The reported adverse drug reactions do not negatively impact the overall compatibility of triptans with breastfeeding. However, breastfeeding women may experience them as unsettling. Awareness of these potential adverse drug reactions is essential and should be weighed against the potential adverse effects of (untreated) symptoms of migraine attacks.

Parental factors that impact the ecology of human mammary development, milk secretion, and milk composition-a report from "Breastmilk Ecology: Genesis of Infant Nutrition (BEGIN)" Working Group 1. Am J Clin Nutr 2023; 117 Suppl 1:S11-S27.

Abstract
The goal of Working Group 1 in the Breastmilk Ecology: Genesis of Infant Nutrition (BEGIN) Project was to outline factors influencing biological processes governing human milk secretion and to evaluate our current knowledge of these processes. Many factors regulate mammary gland development in utero, during puberty, in pregnancy, through secretory activation, and at weaning. These factors include breast anatomy, breast vasculature, diet, and the lactating parent's hormonal milieu including estrogen, progesterone, placental lactogen, cortisol, prolactin, and growth hormone. We examine the effects of time of day and postpartum interval on milk secretion, along with the role and mechanisms of lactating parent-infant interactions on milk secretion and bonding, with particular attention to the actions of oxytocin on the mammary gland and the pleasure systems in the brain. We then consider the potential effects of clinical conditions including infection, pre-eclampsia, preterm birth, cardiovascular health, inflammatory states, mastitis, and particularly, gestational diabetes and obesity. Although we know a great deal about the transporter systems by which zinc and calcium pass from the blood stream into milk, the interactions and cellular localization of transporters that carry substrates such as glucose, amino acids, copper, and the many other trace metals present in human milk across plasma and intracellular membranes require more research. We pose the question of how cultured mammary alveolar cells and animal models can help answer lingering questions about the mechanisms and regulation of human milk secretion. We raise questions about the role of the lactating parent and the infant microbiome and the immune system during breast development, secretion of immune molecules into milk, and protection of the breast from pathogens. Finally, we consider the effect of medications, recreational and illicit drugs, pesticides, and endocrine-disrupting chemicals on milk secretion and composition, emphasizing that this area needs much more research attention.

Abstract
Serotonin is a key regulator of mammary gland homeostasis during lactation. Selective serotonin reuptake inhibitors (SSRIs) are commonly used to treat peripartum depression, but also modulates mammary gland serotonin concentrations and signaling in part through DNA methylation. The objective of this study was to determine mouse mammary transcriptome changes in response to the SSRI fluoxetine and how methyl donor supplementation, achieved by folic acid supplementation, affected the transcriptome. Female C57BL/6J mice were fed either breeder diet (containing 4 mg/kg folic acid) or supplemented diet (containing 24 mg/kg folic acid) beginning 2 weeks prior to mating, then on embryonic day 13 mice were injected daily with either saline or 20 mg/kg fluoxetine. Mammary glands were harvested at peak lactation, lactation day 10, for transcriptomic analysis. Fluoxetine but not folic acid altered circulating serotonin and calcium concentrations, and folic acid reduced mammary serotonin concentrations, however only fluoxetine altered genes in the mammary transcriptome. Fluoxetine treatment altered fifty-six genes. Elovl6 was the most significantly altered gene by fluoxetine treatment along with gene pathways involving fatty acid homeostasis, PPARγ, and adipogenesis, which are critical for milk fat synthesis. Enriched pathways in the mammary gland by fluoxetine revealed pathways including calcium signaling, serotonin receptors, milk proteins, and cellular response to cytokine stimulus which are important for lactation. Although folic acid did not impact specific genes, a less stringent pathway analysis revealed more diffuse effects where folic acid enriched pathways involving negative regulation of gene expression as expected, but additionally enriched pathways involving serotonin, glycolysis, and lactalbumin which are critical for lactation. In conclusion, peripartal SSRI use and folic acid supplementation altered critical genes related to milk synthesis and mammary gland function that are important to a successful lactation. However, folic acid supplementation did not reverse changes in the mammary gland transcriptome altered by peripartal SSRI treatment.

Abstract
Women mobilize up to 10% of their bone mass during lactation to provide milk calcium. About 8%–13% of mothers use selective serotonin reuptake inhibitors (SSRI) to treat peripartum depression, but SSRIs independently decrease bone mass. Previously, peripartal use of the SSRI fluoxetine reduced maternal bone mass sustained post‐weaning and reduced offspring bone length. To determine whether these effects were fluoxetine‐specific or consistent across SSRI compounds, we examined maternal and offspring bone health using the most prescribed SSRI, sertraline. C57BL/6 mice were given 10 mg/kg/day sertraline, from the beginning of pregnancy through the end of lactation. Simultaneously, we treated nulliparous females on the same days as the primiparous groups, resulting in age‐matched nulliparous groups. Dams were euthanized at lactation day 10 (peak lactation, n = 7 vehicle; n = 9 sertraline), lactation day 21 (weaning, n = 9 vehicle; n = 9 sertraline), or 3m post‐weaning (n = 10 vehicle; n = 10 sertraline) for analysis. Offspring were euthanized at peak lactation or weaning for analysis. We determined that peripartum sertraline treatment decreased maternal circulating calcium concentrations across the treatment period, which was also seen in nulliparous treated females. Sertraline reduced the bone formation marker, procollagen 1 intact N‐terminal propeptide, and tended to reduce maternal BV/TV at 3m post‐weaning but did not impact maternal or offspring bone health otherwise. Similarly, sertraline did not reduce nulliparous female bone mass. However, sertraline reduced immunofluorescence staining of the tight junction protein, zona occludens in the mammary gland, and altered alveoli morphology, suggesting sertraline may accelerate mammary gland involution. These findings indicate that peripartum sertraline treatment may be a safer SSRI for maternal and offspring bone rather than fluoxetine.

Abstract
The role the mammary epithelial circadian clock plays in gland development and lactation is unknown. We hypothesized that mammary epithelial clocks function to regulate mammogenesis and lactogenesis, and propose the core clock transcription factor BMAL1:CLOCK regulates genes that control mammary epithelial development and milk synthesis. Our objective was to identify transcriptional targets of BMAL1 in undifferentiated (UNDIFF) and lactogen differentiated (DIFF) mammary epithelial cells (HC11) using ChIP-seq. Ensembl gene IDs with the nearest transcriptional start site to ChIP-seq peaks were explored as potential targets, and represented 846 protein coding genes common to UNDIFF and DIFF cells and 2773 unique to DIFF samples. Genes with overlapping peaks between samples (1343) enriched cell-cell adhesion, membrane transporters and lipid metabolism categories. To functionally verify targets, an HC11 line with Bmal1 gene knocked out (BMAL1-KO) using CRISPR-CAS was created. BMAL1-KO cultures had lower cell densities over an eight-day growth curve, which was associated with increased (p<0.05) levels of reactive oxygen species and lower expression of superoxide dismutase 3 (Sod3). RT-qPCR analysis also found lower expression of the putative targets, prolactin receptor (Prlr), Ppara, and beta-casein (Csn2). Findings support our hypothesis and highlight potential importance of clock in mammary development and substrate transport.

Abstract
Mammary epithelial cells synthesize and secrete norepinephrine (NE) into breast milk to regulate β-casein expression through the adrenergic β2 receptor. We investigated the expression, localization, and roles of NE transporter (NET) in the mammary epithelium during lactation. mRNA and protein levels of NET were determined in primary normal human mammary epithelial cells (pHMECs) and non-malignant human mammary epithelial MCF-12A cells. In nursing CD1 mice, NET localized to the apical membranes of the mammary epithelium. The intracellular NE content of pHMECs incubated with NE increased. Although the β-casein concentration in milk was slightly higher at day 10 than at day 2 of lactation, the NE concentration and lactation-related proteins were only slightly changed on days 2-10. Restraint stress increased the NE concentration in milk from nursing mice and NET protein levels were significantly higher than in non-stressed nursing mice. NET is expressed on the apical membrane of mammary epithelial cells and incorporates NE in milk into cells, potentially regulating the NE concentration in milk.

Abstract
Mammary-derived serotonin has been implicated in breast-to-bone communication during lactation by increasing parathyroid hormone related-protein (PTHrP) in the mammary gland. It is well established that PTHrP acts on the bone to liberate calcium for milk synthesis during lactation; however, the mechanism of serotonin’s regulation of PTHrP has not been fully elucidated. Recently, serotonylation has been shown to be involved in a variety of physiological processes mediated by serotonin. Therefore, we investigated whether serotonylation is involved in serotonin’s regulation of PTHrP in the mammary gland using lactogenically differentiated mouse mammary epithelial cells. We investigated the effect of increased intracellular serotonin using the antidepressant fluoxetine or 5-hydroxytryptophan (serotonin precursor), with or without transglutaminase inhibition and the corresponding action on PTHrP induction and activity. Treatment with fluoxetine or 5-hydroxytryptophan significantly increased intracellular serotonin concentrations and subsequently increased PTHrP gene expression, which was reduced with transglutaminase inhibition. Furthermore, we determined that transglutaminase activity is increased with lactogenic differentiation and 5-hydroxytryptophan or fluoxetine treatment. We investigated whether RhoA, Rac1, and Rab4 were potential serotonylation target proteins. We speculate that RhoA is potentially a serotonylation target protein. Our data suggest that serotonin regulates PTHrP induction in part through the process of serotonylation under lactogenic conditions in mouse mammary epithelial cells.

Abstract
Serotonin (5-HT) is a monoamine and it could regulate cell growth by its receptors working on signaling pathways. 5-HTP is the precursor of 5-HT that help 5-HT synthesis. B cell leukemia/lymphoma 3 (Bcl-3) involved in cell death and proliferation through mitogen activated protein kinase (MAPK) pathway. However, there is little information about the effects of MAPK/Bcl-3 on apoptosis of goat mammary gland epithelial cells (GMECs). The aim of this study is to explore the interaction among 5-HTP, MAPK and Bcl-3 in GMEC apoptosis. In this study, 5-HTP treatment decreased cell apoptosis and promoted phosphorylation of ERK1/2 in GMEC. We also found that the activation and inhibition of ERK1/2 could affect GMEC apoptosis. The Annexin V-FITC/PI staining and western blotting results suggested that 5-HTP decreased GMEC apoptosis through ERK1/2 signaling pathway. And the results of RT-qPCR and western blotting demonstrated that both 5-HTP and ERK1/2 positively regulated Bcl-3 expression. Sum up all the results, we could draw the conclusion that 5-HTP decreased GMEC apoptosis through MAPK/ERK/Bcl-3 pathway.

Abstract
BACKGROUND Although produced by several types of tumours, the role of serotonin on cancer biology is yet to be understood. METHODS The effects of serotonin (5-HT) on human breast cancer cells proliferation, signalling pathways and metabolic profile were evaluated by cytometry, western blotting, qPCR, enzymology and confocal microscopy. RESULTS Our results revealed that incubation of MCF-7 cells with 10 µM 5-HT increased cell growth rate by 28%, an effect that was prevented by the 5-HTR2A/C antagonist, ketanserin. Conversely, increasing concentrations of 5-HT promoted glucose consumption and lactate production by MCF-7 cells. We also showed that increased glucose metabolism is provoked by the upregulation of pyruvate kinase M2 (PKM2) isoform through 5-HTR2A/C-triggered activation of Jak1/STAT3 and ERK1/2 subcellular pathways. However, we noticed a decrease in the rate of produced lactate per consumed glucose as a function of the hormone concentration, suggesting a disruption of the Warburg effect. The latter effect is due to 5-HTR2A/C-dependent mitochondrial biogenesis and metabolism, which is triggered by adenylyl cyclase/PKA, enhancing the oxidation of lactate within these cells. CONCLUSIONS We showed that serotonin, through 5-HTR2A/C, interferes with breast cancer cells proliferation and metabolism by triggering two distinct signalling pathways: Jak1/STAT3 that boosts glycolysis through upregulation of PKM2, and adenylyl cyclase/PKA that enhances mitochondrial biogenesis.

Liu C, Jiang X, Liu G, Wassie T, Girmay S. An Ancient Mutation in the TPH1 Gene is Consistent with the Changes in Mammalian Reproductive Rhythm. Int J Mol Sci 2019; 20:ijms20236065. [PMID: 31810154 PMCID: PMC6928614 DOI: 10.3390/ijms20236065] [Citation(s) in RCA: 4] [Impact Index Per Article: 0.8] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 09/23/2019] [Revised: 11/10/2019] [Accepted: 11/12/2019] [Indexed: 12/13/2022] Open
Abstract
The reproductive rhythm undergoes several changes during the evolution of mammals to adapt to local environmental changes. Although the critical roles of melatonin (MLT) in the formation of reproductive rhythm have been well established, the genetic basis for the changes of reproductive rhythm remains uncertain. Here, we constructed the phylogenetic trees of 13 melatonin synthesis, metabolism and receptor genes, estimated their divergence times, and calculated their selection pressures. Then, we evaluated the effect of positively selected and functionally related mutations on protein activity. Our results showed that there were significant positive selection sites in the three major genes, including tryptophan hydroxylase 1 (TPH1), tryptophan hydroxylase 2 (TPH2) and indoleamine-2,3-dioxygenase 1 (IDO1) that are involved in melatonin synthesis, metabolism and function. At the protein level, amino acids at the 442nd site of TPH1 protein and the 194th, 286th, 315th and 404th sites of IDO1 protein were under positive selection, and the variants of the amino acid in these sites might lead to the changes in protein function. Remarkably, the 442nd site of these positive selection sites is in the tetramerization domain of TPH1 protein, and it is proline or leucine. At this site, 89.5% of the amino acid of non-seasonal reproducing mammals was proline, while that of 88.9% of seasonal reproducing mammals was leucine. This variation of the amino acid was derived from the T/C polymorphism at the 1325th site of the TPH1 gene coding sequence, which significantly altered the TPH1 activity (p < 0.01). Interestingly, the predicted age of the allele C in the mammalian genome appeared about 126.6 million years ago, and allele T appeared about 212.6 million years ago, indicating that the evolution of the TPH1 gene was affected by the two mammalian split events and the K-T extinction event. In conclusion, the T/C polymorphism at the 1325th site in the TPH1 gene coding sequence altered TPH1 activity, suggesting that this polymorphism is consistent with the reproductive rhythm of mammals.

Abstract
G-coupled protein receptors (GCPR) involve several signaling pathways, some of them being coupled with intracellular calcium (Ca2+) mobilization. GPCRs were involved in migration, invasion and metastasis of different types of cancers, including ovarian cancer. Many studies have discussed the essential contribution of GPCRs activated by steroid hormones in ovarian cancer. However, ovarian cancer is also associated with altered signals coming from the nervous system, the immune system or the inflammatory environment, in which GPCRs are ‘sensing’ these molecular signals. Many studies have been oriented so far on ovarian cell lines (most of them being of human cell lines), and only few studies based on animal models or clinical studies have been devoted to the expression changes or functional role of GPCRs in ovarian cancer. In this paper, we review the alterations of GPCRs activated by neurotransmitters (muscarinic receptors, serotonin receptors, dopamine receptors, adrenoceptors) or inflammation-associated molecules (bradykinin receptors, histamine receptors, chemokine receptors) in ovarian cancer and we discuss their potential as histological biomarkers.

Abstract
Milk supply and quality during lactation are critical for progeny survival. Maternal tissues and metabolism, influenced by hormonal changes, undergo modification during lactation to sustain breastfeeding. Two organs that suffer essential adjustment are the mammary glands and the bone; however, renal calcium conservation and calcium absorption from the intestine are also modified. Lactation leads to a transient loss of bone minerals to provide adequate amounts of minerals, including calcium for milk production. Physiological, metabolic, and molecular changes in different tissues participate in providing nutrients for milk production. After weaning, the histological, metabolic, and hormonal modifications that take place in lactation are reverted, and bone remineralization is a central function at this time. This study focuses on the hormonal, metabolic, molecular, and tissue modifications that occur in mammary glands, bone, intestine, and kidneys in the mother during lactation and post-weaning periods.

Abstract
Stress decreases milk components such as milk protein and milk yield. The objective of this study was to investigate whether noradrenaline (NA) in milk constituted a factor associated with stress-induced changes in milk proteins such as β-casein. Breast milk obtained from eight healthy, nursing women contained NA at concentrations ranging from 12.7 to 115.5 nM. The expression of tyrosine hydroxylase (TH), a rate-limiting enzyme of NA synthesis, was observed in primary normal human mammary epithelial cells (HMECs), and in MCF-12A and MCF-10A cell lines. The mean NA concentration in culture medium used by MCF-12A transfected with TH small interfering RNA (siRNA) was significantly lower than that of cells transfected with control siRNA. NA concentration in milk in restraint-stressed nursing mice was significantly higher than that in nonstressed nursing mice, owing to elevated TH expression in the mammary epithelium. The mean β-casein concentration in milk in restraint-stressed mice was significantly lower than that in nonstressed mice. NA treatment resulted in a concentration-dependent decrease in β-casein expression in HMECs. β2 adrenergic receptor (ADRB2) expression was observed in HMECs, MCF-12A, and MCF-10A, and immunohistochemical analysis of ADRB2 using mammary epithelium sections obtained from mice at day 10 of lactation showed that ADRB2 was expressed at the apical membrane of mammary epithelium. Treatment with salbutamol, an ADRB2 stimulant, decreased β-casein expression in a concentration-dependent manner in MCF-12A. Our results showed that endogenous NA derived from mammary epithelial cells likely comprises one of the factors involved in stress-induced changes in milk proteins such as β-casein.

Abstract
BACKGROUND: Depression is consistently shown to predict lower rates of breastfeeding. In a handful of studies, breastfeeding has predicted lower depression symptoms. However, studies demonstrating the latter are limited in their measurement of both depression and breastfeeding and have not followed participants from pregnancy across the postpartum period. RESEARCH AIM: The primary aim of this study was to describe breastfeeding intentions and behaviors for the first 12 months postpartum among nonmedicated depressed, antidepressant-exposed, and control participants. The secondary aim was to examine group differences in the association between depressive symptoms and breastfeeding duration up to 12 months postpartum. METHODS: First-trimester women ( N = 212) were recruited into a prospective longitudinal study. Depressive disorders at baseline were diagnosed using the Structured Clinical Interview for DSM-IV Axis I Disorders, and depressive symptoms were measured at the first and second trimesters and 6 and 12 months postpartum using the Edinburgh Postnatal Depression Scale. Breastfeeding duration, support from family and employers, and perceptions of participants' experience were measured. RESULTS: Depressed women and antidepressant-exposed women reported a trend toward lower rates of intention, initiation, and duration, but this did not reach statistical significance. There was a statistically significant difference on depressive symptoms for women taking antidepressants during pregnancy, compared with controls, when they continued to breastfeed for 12 months postpartum. CONCLUSIONS: This study did not find a strong association between depression or antidepressant use and intention to breastfeed, partner breastfeeding support, or initiation or duration of breastfeeding. However, for women who took antidepressants, there was evidence that breastfeeding for 12 months was associated with lower depressive symptoms.

Abstract
Intrinsic serotonin (5-hydroxytryptamine; 5-HT) synthesized within the mammary epithelium has an important physiological role in milk volume homeostasis in many species including mice, cows, and humans. During lactation, mammary epithelial cells activate 5-HT synthesis by tryptophan hydroxylase 1 (TPH1). TPH1 catalyzes the rate-limiting step in 5-HT biosynthesis within mammary glands. 5-HT synthesized in mammary glands is released into both the apical (milk) and basolateral spaces by a vesicular monoamine transporter. 5-HT released into milk is incorporated by the apical membrane-expressed serotonin reuptake transporter and degraded by the monoamine oxidase A enzyme. Suckling maintains 5-HT at low levels in milk. When the mammary gland becomes filled with milk, 5-HT provides a negative feedback signal that suppresses further milk synthesis in the mammary epithelium. Our research, using human mammary epithelial MCF-12A cells, shows that the expression of β-casein, a differentiation marker, is suppressed via 5-HT-mediated inhibition of signal transducer and activator of transcription 5. Additionally, our results show that reduced β-casein expression in MCF-12A cells is associated with 5-HT7 receptor expression. Furthermore, we show that 5-HT7 receptor-mediated suppression of β-casein expression is involved in the activation of protein kinase A and protein-tyrosine phosphatase 1B. Thus, this mechanism might be associated with the feedback signals by 5-HT within the mammary epithelium. Hence, further research that builds on our findings should include the elucidation of the physiological roles of 5-HT present in milk synthesized by mammary epithelial cells in vivo and its effects on nursing infants.

Abstract
AIMS The aims of the present study were to examine the association between late pregnancy exposure to serotonin reuptake inhibitor (SRI) antidepressants and difficulties in achieving an adequate breast milk supply in women who have given birth to preterm infants, while accounting for the potential impacts of underlying maternal psychiatric illness. METHODS A retrospective cohort study was carried out of 3024 women delivering liveborn preterm infants (<37 weeks' gestation) between January 2004 and December 2008. The primary outcome was postnatal domperidone use, considered to be a valid proxy for the presence and pharmacological management of low milk supply. Relative risks adjusted for maternal sociodemographic characteristics and comorbidities (aRRs) were calculated for low milk supply, comparing women with late pregnancy exposure to SRI antidepressants (n = 86), women with a psychiatric illness but no antidepressant use (n = 126) and women with neither antenatal exposures (n = 2812). RESULTS Compared with non-exposed women, nonmedicated psychiatric illness [aRR 1.64; 95% confidence interval (CI) 1.16, 2.30] but not late pregnancy SRI use (aRR 1.00; 95% CI 0.59, 1.70) was associated with an increased risk of domperidone use, indicative of low milk supply. CONCLUSIONS These findings do not support the previously observed negative impacts of antidepressant use on breastfeeding, instead suggesting that women with an underlying psychiatric illness appear at greatest risk of experiencing low milk supply and could benefit from additional breastfeeding education and support.

Abstract
Serotonin (5-hydroxytryptamine or 5-HT) is a multifunctional bioamine with important signaling roles in a range of physiological pathways. Almost all of the 5-HT in our bodies is synthesized in specialized enteroendocrine cells within the gastrointestinal (GI) mucosa called enterochromaffin (EC) cells. These cells provide all of our circulating 5-HT. We have long appreciated the important contributions of 5-HT within the gut, including its role in modulating GI motility. However, evidence of the physiological and clinical significance of gut-derived 5-HT outside of the gut has recently emerged, implicating 5-HT in regulation of glucose homeostasis, lipid metabolism, bone density, and diseases associated with metabolic syndrome, such as obesity and type 2 diabetes. Although a new picture has developed in the last decade regarding the various metabolic roles of peripheral serotonin, so too has our understanding of the physiology of EC cells. Given that they are scattered throughout the lining of the GI tract within the epithelial cell layer, these cells are typically difficult to study. Advances in isolation procedures now allow the study of pure EC-cell cultures and single cells, enabling studies of EC-cell physiology to occur. EC cells are sensory cells that are capable of integrating cues from ingested nutrients, the enteric nervous system, and the gut microbiome. Thus, levels of peripheral 5-HT can be modulated by a multitude of factors, resulting in both local and systemic effects for the regulation of a raft of physiological pathways related to metabolism and obesity.

We previously reported that serotonin (5-hydroxytryptamine; 5-HT) suppresses β-casein expression, a differentiation marker in mammary epithelial cells, via inhibition of the signal transducer and activator of transcription 5 (STAT5) phosphorylation in the human mammary epithelial cell line, MCF-12A. In this study, we investigated the expression pattern of the different 5-HT receptor subtypes in MCF-12A cells, and identified the receptors involved in 5-HT-mediated suppression of β-casein protein expression. β-Casein mRNA expression was inhibited by 30 µM 5-HT in a time-dependent manner. Treatment with 30 µM 5-HT for 72 h decreased β-casein protein levels and STAT5 phosphorylation (pSTAT5). The cells expressed four 5-HT receptors subtypes (5-HTR1D, 2B, 3A, and 7) at the mRNA and protein level, and their expression was elevated by prolactin (PRL) treatment. Additionally, the mRNA levels of 5-HTR1D and 5-HTR7 were significantly higher than the other 5-HT receptors in the cells. Tryptophan hydroxylase 1 mRNA was detectable in the cells in the absence of PRL, and PRL treatment significantly increased its expression. β-Casein and pSTAT5/STAT5 levels in the cells co-treated with 5-HT and a selective 5-HTR1D inhibitor, BRL15572, were equal to those observed in cells treated with 5-HT alone. However, in the cells co-treated with 5-HT and a selective 5-HTR7 inhibitor, SB269970, β-casein and pSTAT5/STAT5 levels increased in a SB269970 concentration-dependent manner. In conclusion, we showed that 5-HT regulates β-casein expression via 5-HTR7 in MCF-12A human mammary epithelial cells.

Abstract
Serotonin regulates numerous processes in the mammary gland. Our objective was to discover novel genes, pathways and functions which serotonin modulates during lactation. The rate limiting enzyme in the synthesis of non-neuronal serotonin is tryptophan-hydroxylase (TPH1). Therefore, we used TPH1 deficient dams (KO; serotonin deficient, n = 4) and compared them to wild-type (WT; n = 4) and rescue (RC; KO + 100 mg/kg 5-hydroxytryptophan injected daily, n = 4) dams. Mammary tissues were collected on day 10 of lactation. Total RNA extraction, amplification, library preparation and sequencing were performed following the Illumina mRNA-Seq. Overall, 97 and 204 genes (false discovery rate, FDR ≤ 0.01) exhibited a minimum of a 2-fold expression difference between WT vs. KO and WT vs. RC dams, respectively. Most differentially expressed genes were related to calcium homeostasis, apoptosis regulation, cell cycle, cell differentiation and proliferation, and the immune response. Additionally, gene set enrichment analysis using Gene Ontology and Medical Subject Headings databases revealed the alteration of several biological processes (FDR ≤ 0.01) including fat cell differentiation and lipid metabolism, regulation of extracellular signal-related kinase and mitogen-activated kinase cascades, insulin resistance, nuclear transport, membrane potential regulation, and calcium release from the endoplasmic reticulum into the cytosol. The majority of the biological processes and pathways altered in the KO dams are central for mammary gland homeostasis. Increasing peripheral serotonin in the RC dams affects specific pathways that favor lactation. Our data confirms the importance of serotonin during lactation in the mammary gland.

Importance of serotonin (5-HT) and its precursor l-tryptophan for homeostasis and function of skeletal muscle in rats. A morphological and endocrinological study. Acta Histochem 2015; 117:267-74. [PMID: 25805417 DOI: 10.1016/j.acthis.2015.03.003] [Citation(s) in RCA: 16] [Impact Index Per Article: 1.8] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 12/11/2014] [Revised: 03/02/2015] [Accepted: 03/03/2015] [Indexed: 01/08/2023]
Abstract
Serotonin (5-HT) is a neurotransmitter, synthesized in serotonergic neurons of the central nervous system and in enterochromaffin cells of the gastrointestinal tract, which is involved in the regulation of several body functions, including muscle tissue development and growth and its contractile response. l-Tryptophan (l-Trp) is an essential amino acid and precursor of 5-HT. The aim of the present study was to better understand the mechanisms that govern neuroendocrine homeostasis of muscle tissue and emphasize the importance of a diet, complete in all its elements, referring specifically to the essential amino acids such as l-Trp, crucial in several neuroendocrine functions.We analyzed the possible consequences of l-Trp-free diet on 5-HT production and on skeletal muscle morphology and function in young female rats. We also evaluated the eventual alterations of hormone production such as growth hormone (GH), thyroid stimulating hormone (TSH) and thyroid hormones (T3 and T4) that control and regulate growth, metabolism and efficiency of the skeletal muscle. Our results showed a strong decrease of 5-HT, GH, TSH, T3 and T4 levels associated to a clear difference in body weight between experimental and control rats. Moreover, the muscle samples of experimental rats showed histological and ultrastructural alterations. These findings thus supported a strong link between l-Trp, serotonergic system, hormone secretion and morphology of skeletal muscle tissue and thus, the importance of a balanced daily diet.
