Abstract
Purpose This study aimed to identify differentially methylated genes (DMGs) and differentially expressed genes (DEGs) to investigate new biomarkers for the diagnosis and treatment of polycystic ovary syndrome (PCOS). Methods To explore the potential biomarkers of PCOS diagnosis and treatment, we performed methyl-binding domain sequencing (MBD-seq) and RNA sequencing (RNA-seq) on ovarian granulosa cells (GCs) from PCOS patients and healthy controls. MBD-seq was also performed on the ovarian tissue of constructed prenatally androgenized (PNA) mice. Differential methylation and expression analysis were implemented to identify DMGs and DEGs, respectively. The identified gene was further verified by real-time quantitative PCR (RT-qPCR) and methylation-specific PCR (MSP) in clinical samples. Furthermore, ultra-performance liquid chromatography-mass spectrometry (UPLC-MS) was carried out on PCOS patients and healthy controls to identify differential lipid metabolites. Results Compared to the control group, 13,526 DMGs related to the promoter region and 2429 DEGs were found. The function analysis of DMGs and DEGs showed that they were mainly enriched in glycerophospholipid, ovarian steroidogenesis, and other lipid metabolic pathways. Moreover, 5753 genes in DMGs related to the promoter region were screened in the constructed PNA mice. Integrating the DMGs data from PCOS patients and PNA mice, we identified the following 8 genes: CDC42EP4, ERMN, EZR, PIK3R1, ARHGEF18, NECTIN2, TSC2, and TACSTD2. RT-qPCR and MSP verification results showed that the methylation and expression of TACSTD2 were consistent with sequencing data. Additionally, 15 differential lipid metabolites were shown in the serum of PCOS patients. The differential lipids were involved in glycerophospholipid and glycerolipid metabolism. Conclusion Using integration of methylome and lipid metabolites profiling we identified 8 potential epigenetic markers and 15 potential lipid metabolite markers for PCOS. Our results suggest that aberrant DNA methylation and lipid metabolite disorders may provide novel insights into the diagnosis and etiology of PCOS.

[PMID: 36692027 DOI: 10.1515/jom-2022-0129] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 07/05/2022] [Accepted: 01/04/2023] [Indexed: 01/25/2023]
Abstract
Structural skeletal abnormalities are associated with primary immunodeficient (PID) patients. These abnormalities have not been well studied in PID with reference to osteopathic medicine tenets. Osteopathic structural examinations of PID patients with respect to these tenets and the diagnosis of somatic dysfunctions preventing the free flow of lymph fluids back into the circulation and the disruption of the skeletal microenvironment may have an impact on the status of the immune system in patients with a PID. A standardized evaluation was conducted in a patient with a phosphatidylinositol 3-kinase regulatory subunit 1 (PIK3R1) mutation who presented with skeletal abnormalities. A literature review was also conducted to determine the breadth of other PIDs with structural irregularities. Osteopathic structural clinical examinations (OSCEs) were performed by an osteopathic medical student, fellow, and attending after receiving informed consent from the patient. The findings were collected regionally noting severity, tissue texture changes, asymmetry, altered range of motion (ROM), and tenderness according to DO-Touch.NET physical examination and treatment form. A literature review was conducted utilizing various search engines and the textbook, Stiehm's Immune Deficiencies, 4th edition. The significant findings found from the patient were right sidebending rotation cranial strain pattern with decreased left temporal bone motion, temporomandibular joint crepitus, and right deviation upon mandibular opening. The thoracolumbar region revealed tissue tenderness and restricted psoas ROM. Bilateral sacroiliac joint tenderness, right superior sheering, and anterior innominate rotation, along with left-on-left sacral flexion, were associated with valgus knees. The literature search showed multiple other PIDs outside of PIK3R1 that have associated skeletal and structural abnormalities. Irregular skeletal features found in immunodeficient patients may have an additive defect on the immunological responses due to somatic dysfunction impinging on the lymphatic flow to the central circulation. Other different immunodeficient patients suffer from boney structural abnormalities, which may lead to further immune hindrance caused by impingement of flow as well as bone marrow microenvironment impact on the peripheral immunological output. We present the first osteopathic examination with detailed findings of somatic dysfunction in a patient with PID. Future studies on PID patients should require more attention to structure and function, as found by a thorough osteopathic examination in order to unrestrict preformed cellular and humoral components back into the peripheral circulation.

Abstract
We report a boy with typical clinical features of SHORT syndrome alongside a significant microcephaly and severe developmental delay associated with a de novo single nucleotide missense DNA variant resulting in a single amino acid change in codon 486 of the PIK3R1 gene (PIK3R1 c.1456G>A (p.Ala486Thr)). Our report strikingly coincides with another recently published case from Brazil, describing a 23-year-old woman with the same de novo PIK3R1 DNA variant, who also exhibits SHORT syndrome with severe secondary microcephaly and intellectual disability. On review of the literature, we have identified further cases of PIK3R1-related SHORT Syndrome with a similar phenotype. We note all these cases (including ours) have variants located in the -inter SH2 domain (iSH2); we speculate that pathogenic iSH2 located PIK3R1 variants are associated with a different and otherwise unreported clinical picture of SHORT syndrome that presents with microcephaly and/or significant developmental delay/intellectual disability. The pathogenic mechanism of why these variants apparently lead to a different clinical picture of SHORT syndrome remains unknown.

Combining Network Pharmacology with Molecular Docking for Mechanistic Research on Thyroid Dysfunction Caused by Polybrominated Diphenyl Ethers and Their Metabolites. BIOMED RESEARCH INTERNATIONAL 2021; 2021:2961747. [PMID: 34840968 PMCID: PMC8613503 DOI: 10.1155/2021/2961747] [Citation(s) in RCA: 2] [Impact Index Per Article: 0.7] [Reference Citation Analysis] [Abstract] [Track Full Text] [Download PDF] [Figures] [Subscribe] [Scholar Register] [Received: 06/12/2021] [Accepted: 10/05/2021] [Indexed: 11/17/2022]
Abstract
Network pharmacology was used to illuminate the targets and pathways of polybrominated diphenyl ethers (PBDEs) causing thyroid dysfunction. A protein-protein interaction (PPI) network was constructed. Molecular docking was applied to analyze PBDEs and key targets according to the network pharmacology results. A total of 247 targets were found to be related to 16 PBDEs. Ten key targets with direct action were identified, including the top five PIK3R1, MAPK1, SRC, RXRA, and TP53. Gene Ontology (GO) functional enrichment analysis identified 75 biological items. Kyoto Encyclopedia of Genes and Genomes (KEGG) pathway analysis identified 62 pathways mainly related to the regulation of the thyroid hormone signaling pathway, MAPK signaling pathway, PI3K-Akt signaling, pathways in cancer, proteoglycans in cancer, progesterone-mediated oocyte maturation, and others. The molecular docking results showed that BDE-99, BDE-153, 5-OH-BDE47, 5'-OH-BDE99, 5-BDE47 sulfate, and 5'-BDE99 sulfate have a good binding effect with the kernel targets. PBDEs could interfere with the thyroid hormone endocrine through multiple targets and biological pathways, and metabolites demonstrated stronger effects than the prototypes. This research provides a basis for further research on the toxicological effects and molecular mechanisms of PBDEs and their metabolites. Furthermore, the application of network pharmacology to the study of the toxicity mechanisms of environmental pollutants provides a new methodology for environmental toxicology.

Abstract
SHORT syndrome (short stature, hyperextensibility, ocular depression [deeply set eyes], Rieger anomaly and teething delay) is very rare, with a few cases reported in the literature. We report a case of SHORT syndrome with a novel PIK3R1 mutation (c.2008delT) and complicated with severe insulin resistance. Although no treatment guidelines are available to relieve insulin resistance in SHORT syndrome, our treatment plans, including lifestyle intervention combined with metformin and pioglitazone, were carried out for this patient. After the intervention, insulin resistance and hyperinsulinemia in this patient were significantly decreased during a 6-month follow up, which showed the effect of our therapeutic strategies.

Abstract
SHORT syndrome is a rare, multisystem disease named with the acronym arising from short stature, hyperextensibility of joints, ocular depression, Rieger anomaly, and teething delay. Metabolic anomalies such as insulin resistance and diabetes are also present. This disease is related to heterozygous variants in the PIK3R1 and is inherited in an autosomal-dominant manner. In this case report, we present a Taiwanese boy with SHORT syndrome who had growth retardation and dysmorphic features, including a triangular face, prominent forehead, and small chin. We performed anthropometric and laboratory measurements and imaging examinations. We noted no insulin resistance or diabetes. We performed whole exome and Sanger sequencing and confirmed the underlying genetic variant, detecting a heterozygous variant of PIK3R1 (NM_181523.3) (c.1945C > T). In a family survey, his parents indicated no similar clinical symptoms and no gene variant. This case is the first SHORT syndrome in Taiwan. Specific facial dysmorphisms of this case help us confirm the diagnosis with timely genetic testing and then we can provide appropriate management and proper care.
