Embryonic exposure to TPhP elicits osteotoxicity via metabolic disruption in Oryzias latipes

ABSTRACT: Triphenyl phosphate (TPhP) is a widely used organophosphate flame retardant and plasticizer, raising concerns over its health impacts. This study examined the effects of embryonic TPhP exposure on axial skeletal development and metabolism in medaka (Oryzias latipes), a vertebrate fish model relevant to human bone biology. Medaka embryos were exposed to 1 µM TPhP and assessed through early larval stages. TPhP impaired vertebral ossification, causing shortened centra and reduced cartilage in the caudal complex, alongside disrupted distribution of osteoblast-lineage cells. Key osteogenic genes were significantly downregulated at 14 days post-fertilization, and transcriptomic analysis revealed altered mitochondrial pathways linked to skeletal disorders. Functionally, TPhP-exposed larvae showed reduced caudal fin regeneration and decreased metabolic rate and oxygen consumption, consistent with mitochondrial dysfunction. These findings indicate that TPhP disrupts bone development and metabolism by affecting osteoblast differentiation and mitochondrial regulation, highlighting the value of small fish models for studying environmental toxicants and bone metabolic disease risk.

Anthocyanin-treated osteoblast cells [miRNA-seq]

Project description:Our preliminary data shows that dietary ACNs increased osteoblast differentiation and function in human osteoblasts, as well as increased osteoblast differentiation and reduced bone resorption in transgenic medaka. In cultured human osteoblasts, ACNs and resveratrol enhanced growth, reduced apoptosis and increased the expression of HDACs and PGC-1, suggesting that ACNs alter epigenetic regulation and mitochondrial biogenesis

Triphenyl Phosphate (CAS No. 115-86-6): 5-Day Rat Gavage Toxicogenomic Study

Project description:Triphenyl phosphate (TPHP) is an organophosphate flame retardant currently on the market and used as a replacement for phased-out polybrominated diphenyl ethers. Toxicity information on this class of chemicals is inadequate. Herein, the NTP use short-term, in vivo transcriptomic studies to inform potential points of departure for TPHP.

Mouse primary osteoblasts treated with/without BMP2

Project description:Bone morphogenetic proteins (BMPs) regulate many aspects of skeletal development, including osteoblast and chondrocyte differentiation, cartilage and bone formation, and cranial and limb development. Among them, BMP2, one of the most potent osteogenic signaling molecules, stimulates osteoblast differentiation. We used cDNA microarrays to elucidate regulators of BMP-2-induced osteoblast differentiation.

Toxicological Mechanisms and Potencies of Organophosphate Esters in KGN Human Ovarian Granulosa Cells as Revealed by High-throughput Transcriptomics

Project description:Despite the growing number of studies reporting potential risks associated with exposure to organophosphate esters (OPEs), their molecular mechanisms of action remain poorly defined. We used the high-throughput TempO-Seq platform to investigate the effects of frequently detected OPEs on the expression of ~3000 environmentally responsive genes in KGN human ovarian granulosa cells. Cells were exposed for 48 h to one of five OPEs (0.1 to 50 μM): tris(methylphenyl) phosphate (TMPP), isopropylated triphenyl phosphate (IPPP), tert-butylphenyl diphenyl phosphate (BPDP), triphenyl phosphate (TPHP), or tris(2-butoxyethyl) phosphate (TBOEP). The sequencing data indicate that four OPEs induced transcriptional changes, whereas TBOEP had no effect within the concentration range tested. Multiple pathway databases were used to predict alterations in biological processes based on differentially expressed genes. At lower concentrations, inhibition of the cholesterol biosynthetic pathway was the predominant effect of OPEs; this was likely a consequence of intracellular cholesterol accumulation. At higher concentrations, BPDP and TPHP had distinct effects, primarily affecting pathways involved in cell cycle progression and other stress responses. Benchmark concentration (BMC) modelling revealed that BPDP had the lowest transcriptomic point of departure. However, in vitro to in vivo extrapolation modeling indicated that TMPP was bioactive at lower concentrations than the other OPEs. We conclude that these new approach methodologies provide information on the mechanism(s) underlying the effects of data-poor compounds and assist in the derivation of protective points of departure for use in chemical read-across and decision-making.

Medaka Reciprocal cross RNAseq

Project description:Medaka fish is a long standing genetic model organism from the 1930s. Uniquely amongstvertebrates Medaka fish can be routinely inbred from the wild (laboratory mice are inbred, butthis does not happen as a routine process from wild individuals), leading to a large number offully inbred wild-derived strains. As part of a broader collaboration I am part of a project toinbred over 100 wild derived strains of Medaka and use them in a similar manner toArabidopsis and Drosophila wild derived lines.To help explore the phenotyping possibilities in this context, we have taken alreadyestablished wild Medaka lines and done reciprocal F1 crosses between 3 strains, and have 4tissues, and a number of parental tissues, giving a total of 40 samples. By doing RNA-seq onthese tissues we do a number of things:(a) assess the level of allele specific expression in Medaka(b) test whether there is any imprinting (parent of origin) in fish. This is thought to not be thecase, but in fact has not been well tested (not least because getting truly inbred fish is hard)(c) assess the level of random allelic activation in brain(d) assess the feasibility for RNAseq based phenotyping in Medaka, providing preliminarydata for future proposals.This data is part of a pre-publication release.
