Abstract
Glial Fibrillary Acidic Protein (GFAP) and Ubiquitin C-terminal hydrolase (UCH-L1) have been FDA-approved for clinical use in mild and moderate traumatic brain injury (TBI). Understanding sex differences in their diagnostic accuracy over time will help inform clinical practice. We sought to evaluate the sex differences in the temporal profile of GFAP and UCH-L1 in a large cohort of trauma patients presenting to the emergency department. To compare the biomarkers' diagnostic accuracy in male versus female patients for detecting mild TBI (MTBI), and traumatic intracranial lesions on head CT. This prospective cohort study enrolled female and male adult trauma patients presenting to a Level 1 Trauma Center. All patients underwent rigorous screening to determine whether or not they had experienced a MTBI. Of 3025 trauma patients assessed, 1030 met eligibility criteria and 446 declined. Initial blood samples were obtained in 584 patients enrolled within 4 h of injury. Repeated blood sampling was conducted at 4, 8, 12, 16, 24, 36, 48, 60, 72, 84, 96, 108, 120, 132, 144, 156, 168, and 180-h post-injury. The main outcomes included the diagnostic accuracy in detection of MTBI and traumatic intracranial lesions on head CT scan. A total of 1831 samples were drawn in 584 patients over 7 days, 362 (62%) were male and 222 (38%) were female. The pattern of elevation was similar in both sexes. Although the pattern of elevation was similar between male and female for both biomarkers, male patients had significantly higher concentrations of UCH-L1 compared to female patients at several timepoints post-injury, particularly within 24 h of injury. There were no significant differences in diagnostic accuracy for detecting MTBI or for detecting CT lesions between male and female patients at any timepoint for both GFAP and UCH-L1. Although patterns of GFAP and UCH-L1 release in trauma patients over a week post-injury was similar between the sexes, there were significantly higher concentrations of UCH-L1 in males at several timepoints post-injury. Despite this, the overall diagnostic accuracies of both GFAP and UCH-L1 over time for detecting MTBI and CT lesions were not significantly different between male and female trauma patients.

UCHL1, besides leptin and fibronectin, also could be a sensitive marker of the relapsing-remitting type of multiple sclerosis. Sci Rep 2023; 13:3423. [PMID: 36854961 PMCID: PMC9974955 DOI: 10.1038/s41598-023-30237-3] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 11/08/2022] [Accepted: 02/20/2023] [Indexed: 03/02/2023] Open
Abstract
Research on the markers of immunoregulatory response in multiple sclerosis (MS) is still of great importance. The aim of our study was the evaluation of leptin, fibronectin, and UCHL1 concentrations as potential biomarkers of a relapsing-remitting type of MS (RRMS). Surface Plasmon Resonance Imaging (SPRI) biosensors were used for the evaluation of proteins concentrations in 100 RRMS patients and 46 healthy volunteers. Plasma leptin, fibronectin, and UCHL1 concentrations were significantly higher in RRMS patients compared to the control group (p < 0.001, respectively). UCHL1 concentration evaluation revealed the highest diagnostic sensitivity (100%) and negative predictive value (100%) in differentiating MS patients from healthy individuals. There was no significant difference in the UCHL1 concentrations depending on the patient's sex, the presence of relapse within the last 24 months, and the EDSS value (p > 0.05, respectively). In RRMS patients UCHL1 concentration positively correlated with fibronectin levels (r = 0.3928; p < 0.001). In the current cohort of patients plasma UCHL1 concentration was independent of the time of MS relapse and the severity of neurological symptoms. Thus current study may indicate that plasma UCHL1, besides leptin and fibronectin, also could be a promising high-sensitive potential biomarker of relapsing-remitting type of MS. However, these results should be validated with a larger group of patients, taking into account neuroimaging and cerebrospinal fluid analysis data, and by comparing them to patients with other neurological diseases as a control group.

Abstract
Cleft lip and palate is a common congenital birth defect in humans. Its incidence rate in China is as high as 1.82%, and is now a frequent deformity observed among the Chinese population; moreover, it varies across regions. Although the etiology of nonsyndromic cleft lip with or without cleft palate (NSCL/P) has been widely investigated, the results are inconsistent. The specific genes and mechanisms responsible for NSCL/P have not been fully understood. Whole exome sequencing (WES) is a new strategy for studying pathogenic genes. WES studies on NSCL/P have not been conducted in East China. Therefore, the aim of this study was to screen candidate genes of NSCL/P in East China using WES and analyze the temporal and spatial expressions of the candidate genes during embryonic palatal development. WES was performed in 30 children with NSCL/P from East China to screen candidate genes. A bioinformatics analysis was performed using commercially available software. Variants detected by WES were validated by immunohistochemistry and western blotting. After WES, 506,144 single-nucleotide variant sites were found. The results of database comparison, functional analysis, and mass spectrometry revealed that only the laminin alpha 5 (LAMA5) gene (site: rs145192286) was associated with NSCL/P. Immunohistochemistry results showed that LAMA5 expression in the medial edge epithelium changed with formation, lifting, and contact during palatogenesis. Almost no LAMA5 expression was detected in the palatal mesenchyme or after palatal fusion. Western blotting and immunohistochemistry results showed consistent trends. In conclusion, the WES results shows that the mutation at the site (rs145192286) of LAMA5 is associated with NSCL/P. The temporal and spatial expressions of LAMA5 during palatal development further demonstrate the involvement of this gene. Therefore, we speculate that LAMA5 is a new candidate pathogenic gene of NSCL/P. The identification of new pathogenic genes would help elucidate the pathogenesis of NSCL/P and provide a scientific basis for the prenatal diagnosis, prevention, and treatment of NSCL/P.

Abstract
BACKGROUND Recent studies have shown that ubiquitin-mediated cell apoptosis can modulate protein interaction and involve in the progress of oocyte maturation and spermatogenesis. As one of the key regulators involved in ubiquitin signal, ubiquitin C-terminal hydrolase L1 (UCHL1) is considered a molecular marker associated with spermatogonia stem cells. However, the function of UCHL1 was wildly reported to regulate various bioecological processes, such as Parkinson's disease, lung cancer, breast cancer and colon cancer, how UCHL1 affects the mammalian reproductive system remains an open question. METHODS We identified papers through electronic searches of PubMed database from inception to July 2022. RESULTS Here, we summarize the important function of UCHL1 in controlling mammalian oocyte development, regulating spermatogenesis and inhibiting polyspermy, and we posit the balance of UCHL1 was essential to maintaining reproductive cellular and tissue homeostasis. CONCLUSION This study considers the 'double-edged sword' role of UCHL1 during gametogenesis and presents new insights into UCHL1 in germ cells.

Abstract
A cavernous hemangioma, well-known as vascular malformation, is present at birth, grows proportionately with the child, and does not undergo regression. Although a cavernous hemangioma has well-defined histopathological characteristics, its origin remains controversial. In the present study, we characterized the cellular heterogeneity of a cavernous hemangioma using single-cell RNA sequencing (scRNA-seq). The main contribution of the present study is that we discovered a large number of embryonic mesenchymal stem cells (MSCs) in a cavernous hemangioma and proposed that cavernous hemangiomas may originate from embryonic MSCs. Further analysis of the embryonic MSCs revealed that: 1) proinflammatory cytokines and related genes TNF, TNFSF13B, TNFRSF12A, TNFAIP6, and C1QTNF6 are significantly involved in the MSC-induced immune responses in cavernous hemangiomas; 2) UCHL1 is up-regulated in the embryonic MSC apoptosis induced by proinflammatory cytokines; 3) the UCHL1-induced apoptosis of MSCs may play an important role in the MSC-induced immune responses in cavernous hemangiomas; and 4) UCHL1 can be used as a marker gene to detect embryonic MSCs at different apoptosis stages. In addition to MSCs, ECs, macrophages, T lymphocytes and NKCs were intensively investigated, revealing the genes and pathways featured in cavernous hemangiomas. The present study revealed the origin of cavernous hemangiomas and reported the marker genes, cell types and molecular mechanisms, which are associated with the origin, formation, progression, diagnosis and therapy of cavernous hemangiomas. The better understanding of the MSC-induced immune responses in benign tumours helps to guide future investigation and treatment of embryonic MSC-caused tumours. Our findings initiated future research for the rediscovery of MSCs, cancers/tumours and the UCHL1-induced apoptosis.

Abstract
Spermatogenesis is a prolonged and highly ordered physiological process that produces haploid male germ cells through more than 40 steps and experiences dramatic morphological and cellular transformations. The ubiquitin proteasome system (UPS) plays central roles in the precise control of protein homeostasis to ensure the effectiveness of certain protein groups at a given stage and the inactivation of them after this stage. Many UPS components have been demonstrated to regulate the progression of spermatogenesis at different levels. Especially in recent years, novel testis-specific proteasome isoforms have been identified to be essential and unique for spermatogenesis. In this review, we set out to discuss our current knowledge in functions of diverse USP components in mammalian spermatogenesis through: (1) the composition of proteasome isoforms at each stage of spermatogenesis; (2) the specificity of each proteasome isoform and the associated degradation events; (3) the E3 ubiquitin ligases mediating protein ubiquitination in male germ cells; and (4) the deubiquitinases involved in spermatogenesis and male fertility. Exploring the functions of UPS machineries in spermatogenesis provides a global picture of the proteome dynamics during male germ cell production and shed light on the etiology and pathogenesis of human male infertility.

BDNF and IL-8, But Not UCHL-1 and IL-11, Are Markers of Brain Injury in Children Caused by Mild Head Trauma. Brain Sci 2020; 10:brainsci10100665.

Abstract
The aim of the study was to check whether the plasma levels of brain-derived neurotrophic factor (BDNF), interleukin-8 (IL-8), interleukin-11 (IL-11) and ubiquitin C-terminal hydrolase L1 (UCHL-1) change in children with mild head trauma (N = 29) compared to controls (N = 13). Protein concentration in children with mild head trauma (12 children with mild concussion without loss of consciousness and 17 children with severe concussion and loss of consciousness) and the control group were measured by means of the Enzyme-Linked Immunosorbent Assay (ELISA) method. IL-8 and BDNF concentration was statistically higher in the group of children with mild head trauma (9.89 pg/mL and 2798.00 pg/mL, respectively) compared to the control group (7.52 pg/mL and 1163.20 pg/mL, respectively). BDNF concentration was significantly higher in children with severe concussion and loss of consciousness (3826.00 pg/mL) than in the control group. None of the tested proteins differed significantly between children with mild concussion without loss of consciousness and children with severe concussion and loss of consciousness. BDNF and IL-8 may be sensitive markers of brain response to mild head trauma in children. The lack of statistical differences for BDNF and IL-8 between children with mild or severe concussion could indicate that their elevated levels may not result from significant structural brain damage but rather reflect a functional disturbance.

Abstract
Ubiquitin C-terminal hydrolase 1 (UCHL1) is an enzyme unique for its multiple activity - both ligase and hydrolase. UCHL1 was first identified as an abundant protein found in the brain and testes, however its expression is not limited to the neuronal compartment. UCHL1 is also highly expressed in carcinomas of various tissue origins, including those from brain, lung, breast, kidney, colon, prostate, pancreas and mesenchymal tissues. Loss-of-function studies and an inhibitor for UCHL1 confirmed the importance of UCHL1 for cancer therapy. So far biological significance of UCHL1 was described in the following processes: spermatogenesis, oncogenesis, angiogenesis, cell proliferation and differentiation in skeletal muscle, inflammation, tissue injury, neuronal injury and neurodegeneration.

Abstract
PURPOSE Laminin 5 and collagen IV are the main compounds of the extracellular matrix of the germinal epithelium. The purpose of this study was to evaluate the concentration of these two markers of fibrosis in the plasma of boys with congenital unilateral cryptorchidism. MATERIALS AND METHODS The study group comprised 43 boys aged 1-3 years with congenital unilateral cryptorchidism. The control group included 54 healthy, age matched boys, admitted for planned hernioplasty. To assess laminin 5 and collagen IV in the plasma of boys with unilateral cryptorchidism, we used a new biosensor with Surface Plasmon Resonance Imaging technique detection. RESULTS The median concentration of laminin 5 and collagen IV in the serum of boys with congenital, unilateral cryptorchidism was higher than in boys with normal scrotal testis. The difference was statistically significant (p < 0.0001). We did not notice a correlation between a higher position of the testicles in the inguinal and/or their condition and levels of laminin 5 and collagen IV in the plasma. CONCLUSION Laminin 5 and collagen IV concentrations in the plasma were higher in patients with congenital unilateral cryptorchidism. We believe that in the future, our results could be compared with fertility level in adulthood.

Abstract
The matrix metalloproteinases are enzymes capable of remodeling of extracellular matrix, and modulate the behavior of cells. Maturation of gubernaculum and spermatogenesis demand proper equilibrium of metalloproteinases and their inhibitors. The aim of this survey was to investigate the levels of matrix metalloproteinase type 1 (MMP-1) and matrix metalloproteinase type 2 (MMP-2) in the plasma of children with unilateral cryptorchidism along with levels of Insulin-like Peptide 3 (INSL3) and inhibin B. INSL3 have a role in gubernaculum development. Inhibin B is produced by Sertoli cells, and its levels reflect the status of the testis germinative epithelium. Fifty boys with an undescended testicle, aged 1-4 years (median = 2.4 years) were enrolled into the study. Fifty boys with inguinal hernia aged 1-4 years, served as controls (median age = 2.1 years). Investigators assessed the MMP-1 and MMP-2 concentrations using Surface Plasmon Resonance Imaging. The levels of INSL-3 and inhibin B were assessed using commercial enzyme-linked immunosorbent assay ELISA. The median concentration of MMP-1 and MMP-2 in the blood plasma of patients with unilateral cryptorchidism, was nearly 2-folds higher than in controls. The great area under the ROC curve with the cut off value of 0.865 for MMP-1, and 0.819 for MMP-2, indicates the high clinical sensitivity and specificity of the test of plasma levels of MMP-1 and MMP-2 for boys with cryptorchidism. The increased plasma levels of MMP-1 and MMP-2, probably reflect the level of apoptosis of the germ cells in undescended testicles, in response to the heat stress during the period of prepubertal testis development. In the group of cryptorchid boys, we found slightly lower concentrations of INSL3, without statistical significance and without correlation with MMP-1 and MMP-2 levels. There were no significant differences in the levels of inhibin B in the group of boys with cryptorchidism and boys with inguinal hernia and it also did not correlate with MMP-1 and MMP-2 concentrations.

Recent Progress in Surface Plasmon Resonance Biosensors (2016 to Mid-2018). BIOSENSORS-BASEL 2018; 8:bios8040132. [PMID: 30558384 PMCID: PMC6316629 DOI: 10.3390/bios8040132] [Citation(s) in RCA: 35] [Impact Index Per Article: 5.8] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Subscribe] [Scholar Register] [Received: 10/28/2018] [Revised: 12/09/2018] [Accepted: 12/12/2018] [Indexed: 12/31/2022]
Abstract
More than 50 papers on surface plasmon resonance biosensors, published between 2016 and mid-2018, are reviewed. Papers concerning the determination of large particles such as vesicles, exosomes, cancer cells, living cells, stem cells, and microRNA are excluded, as these are covered by a very recent review. The reviewed papers are categorized into five groups, depending on the degree of maturity of the reported solution; ranging from simple marker detection to clinical application of a previously developed biosensor. Instrumental solutions and details of biosensor construction are analyzed, including the chips, receptors, and linkers used, as well as calibration strategies. Biosensors with a sandwich structure containing different nanoparticles are considered separately, as are SPR (Surface Plasmon Resonance) applications for investigating the interactions of biomolecules. An analysis is also made of the markers determined using the biosensors. In conclusion, there is shown to be a growing number of SPR applications in the solution of real clinical problems.

Targeting YOD1 by RNA Interference Inhibits Proliferation and Migration of Human Oral Keratinocytes through Transforming Growth Factor- β3 Signaling Pathway. BIOMED RESEARCH INTERNATIONAL 2018; 2018:6254308. [PMID: 30345304 PMCID: PMC6158930 DOI: 10.1155/2018/6254308] [Citation(s) in RCA: 5] [Impact Index Per Article: 0.8] [Reference Citation Analysis] [Abstract] [Track Full Text] [Download PDF] [Figures] [Subscribe] [Scholar Register] [Received: 04/10/2018] [Accepted: 08/19/2018] [Indexed: 11/17/2022]
Abstract
Objective We have identified a gene YOD1 encoding deubiquitinating enzyme (DUB) responsible for nonsyndromic cleft lip with or without cleft palate (NSCL/P). We aimed to determine the effects of YOD1 RNA interference (RNAi) on cell proliferation and migration, playing an important role in lip and palate formation, and to clarify whether the mechanisms involved TGF-β3 signaling associated with NSCL/P. Methods RNAi was applied to construct vectors expressing YOD1 small interference RNAs (siRNAs). The vectors were transfected into the human oral keratinocytes (HOK) cells. The cell proliferation and migration were evaluated by the cell counting kit-8 (CCK-8) assay and wound healing assay, respectively. The mRNA levels were detected by quantitative real-time reverse transcription-polymerase chain reaction (qRT-PCR). The protein levels were investigated by western blotting. Results The proliferation of YOD1 siRNA-transfected HOK cells was remarkably inhibited. The migration rate was significantly decreased in the YOD1 siRNA-transfected HOK cells. The TGF-β3 mRNA and protein levels were decreased significantly by siRNA-mediated knockdown of YOD1. YOD1 RNAi reduced the phosphor-Smad2/3 levels significantly. Conclusions YOD1 RNAi may inhibit cell proliferation and migration associated with the pathogenesis of NSCL/P through TGF-β3 signaling. The study indicates a novel role of YOD1 in regulating TGF-β3 signaling to affect cell proliferation and migration resulting in NSCL/P.
