Abstract
Background Angiomyolipoma with epithelial cysts (AMLEC) is an extremely rare subtype of kidney angiomyolipoma that contains epithelial-lined cysts. The most distinctive immunohistochemical feature of AMLEC is its immunoreactivity with melanocytic markers. AMLEC also has a distinct histological structure, which aids in its pathological diagnosis. To date 27 cases of AMLEC have been reported in 11 case series. However, the molecular biology underlying the pathogenesis of AMLEC remains unexplored. Case report A 30-year-old female was diagnosed with AMLEC and underwent partial nephrectomy. Histologically, the cross-section of cystic tissue revealed a multilocular appearance, with some cysts containing thrombus-like material, and the wall thickness was approximately 0.2 ~ 0.3 cm. Additionally, the compact subepithelial cellular stroma showed strong and diffuse nuclear labeling for estrogen receptor, progesterone receptor, and CD10, as well as HMB45 and Melan A, which are markers of melanocytic differentiation. Furthermore, using a DNA targeted sequencing panel with next-generation sequencing, we identified a nonsense mutation in TSC Complex Subunit 2 (TSC2) gene, resulting in the formation of a premature termination codon. Moreover, the mutated genes found to be enriched in the PI3K-AKT pathway. The patient in this case had a favorable postoperative follow-up at 3 months. Conclusion To the best of our knowledge, this study represents the first analysis of genotype mutations in AMLEC, providing valuable insights for future clinical practice. These findings have significant potential in guiding the understanding and management of AMLEC, paving the way for further research and advancements in the field.

Abstract
BACKGROUND Lung Adenocarcinoma (LUAD), a common and aggressive form of lung cancer, poses significant treatment challenges due to its low survival rates. AIM To better understand the role of ferroptosis driver genes in LUAD, this study aimed to explore their diagnostic and prognostic significance, as well as their impact on treatment approaches and tumor immune function in LUAD. METHOD To accomplish the defined goals, a comprehensive methodology incorporating both in silico and wet lab experiments was employed. A comprehensive analysis was conducted on a total of 233 ferroptosis driver genes obtained from the FerrDB database. Utilizing various TCGA databases and the RT-qPCR technique, the expression profiles of 233 genes were examined. Among them, TP53, KRAS, PTEN, and HRAS were identified as hub genes with significant differential expression. Notably, TP53, KRAS, and HRAS exhibited substantial up-regulation, while PTEN demonstrated significant down-regulation at both the mRNA and protein levels in LUAD samples. The dysregulation of hub genes was further associated with poor overall survival in LUAD patients. Additionally, targeted bisulfite-sequencing (bisulfite-seq) analysis revealed aberrant promoter methylation patterns linked to the dysregulation of hub genes. RESULT & DISCUSSION Furthermore, hub genes were found to participate in diverse oncogenic pathways, highlighting their involvement in LUAD tumorigenesis. By leveraging the diagnostic and prognostic potential of ferroptosis driver hub genes (TP53, KRAS, PTEN, and HRAS), significant advancements can be made in the understanding and management of LUAD pathogenesis. CONCLUSION Therapeutic targeting of these genes using specific drugs holds great promise for revolutionizing drug discovery and improving the overall survival of LUAD patients.

Abstract
The early diagnosis of lung cancer is closely associated with the decline of mortality. A panel consisting of seven lung cancer-related autoantibodies (7-AABs) has been shown to be a reliable and specific indicator for the early detection of lung cancer, with a specificity of ~90% and a positive predictive value of ~85%. However, its low sensitivity and negative predictive value limit its wide application. To improve its diagnostic value, the diagnostic efficiencies of 7-AABs in combination with non-specific tumor markers were retrospectively investigated for the detection of early-stage lung cancer. A total of 217 patients with small lung nodules who presented with ground-glass opacity or solid nodules as well as 30 healthy controls were studied. The concentrations of 7-AABs and heat shock protein 90a (HSP90a) were assessed using ELISA. Automated flow fluorescence immune analysis was used for the assessment of CEA, CYFRA21-1, CA199 and CA125 levels. The results showed that 7-AABs + HSP90a possessed a remarkably improved diagnostic efficiency for patients with small pulmonary nodules or for patients with lung nodules of different types, which suggested that 7-AABs in combination with HSP90a could have a high clinical value for the improvement of the diagnostic efficiency of early-stage lung cancer.

Abstract
AIM To improve the accuracy of diagnosis of Rosai-Dorfman disease (RDD) by summarising the computed tomography (CT) and magnetic resonance imaging (MRI) characteristics. MATERIALS AND METHODS The clinical manifestations, imaging findings, and pathological characteristics of 14 patients with histopathologically confirmed RDD were analysed retrospectively and a literature review was undertaken. RESULTS Of the 14 patients, nine had multiple lesions and five had single lesions. Eight patients had extranodal lesions, while six had mixed-type lesions. In patients with head and neck lesions, plain CT/MRI revealed irregularly shaped, well-defined, homogeneous, and mainly progressive lesions, with marked homogeneous enhancement on multiphasic contrast-enhanced imaging. One patient had dural lesions, one of which iso-intense to grey matter, with patchy hypo-intensity on T2-weighted imaging, meningeal tail signs, and characteristic crabfoot-like enhancement. Three patients with skeletal system involvement exhibited osteolytic bone destruction without sclerosis at the edges, associated soft-tissue masses, or periosteal reactions. Two patients had well-defined subcutaneous lesions, inhomogeneous density, and progressive parenchymal enhancement on contrast-enhanced CT. One patient had multiple intestinal lesions with inhomogeneous nodular thickening of the blind ascending colon and ileum, with marked and progressive enhancement. CONCLUSION RDD involvement is mainly multifocal, primarily in the head and neck regions. Plain CT/MRI revealed well-defined, irregularly shaped lesions with homogeneous density/signal, with marked and progressive enhancement on multiphasic contrast-enhanced imaging; however, histopathology is still required to confirm the diagnosis of RDD.

Abstract
BACKGROUND Circular RNAs (circRNAs) are key regulators in the progression of various cancers. Abnormal DNA methylation patterns feature prominently in the regulation of the expression of tumor-related genes. This study is aimed at investigating the molecular mechanism of circ_0040809 affecting colorectal cancer (CRC) progression by regulating DNA methyltransferase 1 (DNMT1). METHODS circ_0040809 was selected from the circRNA microarray datasets (GSE142837 and GSE138589). Quantitative real-time polymerase chain reaction (qRT-PCR) was conducted to examine the expression of circ_0040809, miR-515-5p, and DNMT1 mRNA in paired cancerous and paracancerous tissues of 40 CRC patients, as well as in cell lines. Western blotting was conducted for detecting DNMT1 protein expression in CRC cells. Cell proliferation, migration, and apoptosis were assessed through CCK-8, Transwell, and flow cytometry assays. Bioinformatics and dual-luciferase gene assay were conducted to predict and verify, respectively, the targeted relationships between circ_0040809 and miR-515-5p, as well as between miR-515-5p and DNMT1 mRNA. RESULTS In CRC tissues and cells, circ_0040809 and DNMT1 expression are markedly increased, whereas miR-515-5p expression is decreased. Also, high circ_0040809 expression is significantly linked to shorter overall survival. Cell function compensation experiments reveal that circ_0040809 silencing inhibits CRC cell proliferation and migration and promotes apoptosis, while circ_0040809 overexpression has the opposite effects. Mechanistically, circ_0040809 competitively binds to miR-515-5p to elevate DNMT1 expression. Rescue assay reveals that overexpressed miR-515-5p partly counteracts the tumor-facilitating impact of circ_0040809. CONCLUSIONS circ_0040809 facilitates CRC cell proliferation and migration, and inhibits apoptosis, through modulating miR-515-5p/DNMT1 axis. Our study implies that targeting circ_0040809 may be a therapy strategy for CRC treatment.

Abstract
OBJECTIVE Circular RNAs (circRNAs) could regulate gene expression which may induce tumor occurrence and progression. In the current study, we first investigated the expression of circMTO1 in osteosarcoma, and the underlying mechanism was further elucidated. PATIENTS AND METHODS Circular RNA microarrays were used to identify the differential expression of circRNAs in osteosarcoma tissues and the corresponding normal tissues. qRT-PCR was used to examine the level of circMTO1 in osteosarcoma tissues and cell lines. In addition, circMTO1 overexpression was constructed using lentiviral transfection in cell lines. Subsequently, the Cell Counting Kit-8 (CCK8), cell migration and invasion, and flow cytometry were used to investigate the effect of circMTO1 on the biological functions of cells. The Western Blot and the recovery experiments were used to explore the potential mechanism. RESULTS Here, we measured 20 circRNAs which were downregulated in osteosarcoma tissues using circRNA microarray. CircMTO1 expression was decreased in osteosarcoma cell lines. Besides, circMTO1 could inhibit cell proliferation, migration and invasion, and induced apoptosis in osteosarcoma cells. Bioinformatics analysis showed that circMTO1 serves as a sponge for miR-630 and KLF6 is a direct target of miR-630. Furthermore, circMTO1 functions through regulation of miR-630/KLF6 axis. CONCLUSIONS Our study suggests circMTO1 could suppress osteosarcoma progression by regulating miR-630/KLF6 axis, which may highlight the diagnostic and therapeutic potential of these molecules in osteosarcoma treatment.

Abstract
The chemokine ligand C-X-C motif chemokine ligand 11 (CXCL11) is involved in the progression of various cancers, but its biological roles in colorectal cancer (CRC) remain confused. Therefore, the prognostic value and underlying mechanism of CXCL11 in CRC were preliminarily evaluated. Three independent datasets were used for mRNA-related analysis: one dataset from the Cancer Genome Atlas (TCGA, n = 451) and two single-cell RNA sequencing (scRNA-seq) datasets from Gene Expression Omnibus (GEO): GSE146771 and GSE132465. In addition, a colon adenocarcinoma (COAD) patient cohort (the Yijishan Hospital cohort, YJSHC, n = 108) was utilized for analysis of cell infiltration by immunohistochemistry. We determined the distribution of CXCL11 in tumor tissue across all TCGA cancers and found that CXCL11 expression was significantly upregulated in both COAD and rectal adenocarcinoma (READ). However, the upregulation of CXCL11 mRNA was associated with a better prognosis in COAD, but not in READ. Within the YJSHC, the patients with a high abundance of intratumoral CXCL11+ cells had prolonged survival (p = 0.001). Furthermore, we found that the high CXCL11 expression group had a higher proportion of antitumor immune cells, and a lower proportion of protumor immune cells. Additionally, we discovered the changes of gene expression and enriched immune pathway network mediated by CXCL11. Interestingly, both cytotoxic genes (IFNG, GZMA, GZMB, GZMK, GZMM, and PRF1) and immunosuppressive molecules, including PD-L1, were positively correlated with CXCL11 expression. CXCL11, which promoted antitumor immunity to benefit survival, was identified as an independent prognostic biomarker in patients with COAD.

Abstract
Abstract
Introduction
Insomnia is a novel and modifiable risk factor for incident cardiovascular disease (CVD). However, identification of early markers of subclinical CVD in diagnosed insomnia is understudied. Our aim for this ongoing study is to contrast markers of cardiovascular structure and function between people with insomnia and good-sleeping controls.
Methods
Persons with insomnia (met ICSD-III criteria) and good sleeping controls (<8 Insomnia Severity Index, mean 8-night SOL and WASO<31min) were recruited from the community. Twenty-two adults (21-39y; 55% women) with no history of CVD, diabetes, inflammatory conditions, significant hypertension, or current sleep-disordered breathing (WatchPat200, Itamar Medical) were enrolled and underwent fasting cardiovascular testing. Testing included: Central augmented aortic pressure (AP) and carotid-femoral pulse wave velocity (cfPWV) for vascular stiffness; brachial artery flow mediated dilation (FMD) to assess endothelial function; and 2D echocardiography to assess ejection fraction (EF%), left ventricular global longitudinal strain (LVGLS), left atrial volume index (LAVI), mitral valve E/e’ ratio (E/e’), and lateral e’. ANCOVA models, adjusting for age, comparing persons with insomnia (n=6) to good sleeping controls (n=16) on each cardiovascular measure were conducted.
Results
AP (range:-5,10mmHg), cfPWV (range: 4.8-7.6m/s), EF% (range:55.0-72.0%), LVGLS (range:-26,-19%) LAVI (range:14.1-26.7mL/m2), E/e’ (range:3.2-7.8), and lateral e’ (range:0.09-0.22cm/sec) were all within normal ranges according to age and sex normative standards. Mean FMD was 8.8% (SD=4.3, range:4.3-19.8%). Age adjusted ANCOVA models indicated that the insomnia group had significantly worse cardiovascular function than good sleeping controls on cfPWV (M=6.8±0.3 vs. M=5.7±0.2; p=0.004), EF% (M=60.0±1.7 vs. M=65.2±1.0; p=0.017), LVGLS (M=-21.6±0.6 vs. M=-24.3±0.4; p=0.001), and lateral e’ (M=0.12±0.01 vs. M=0.18±0.01; p=0.003). No group differences were found for AP, FMD, LAVI, and E/e’.
Conclusion
Among relatively healthy young adults, people with insomnia had greater arterial stiffness and worse left ventricular systolic and diastolic functioning.

Abstract
OBJECTIVE The aim of this study was to observe the therapeutic effects of three sequential drug-based treatments according to the cell cycle in rats with adriamycin-induced nephropathy. MATERIALS AND METHODS A rat model of adriamycin-induced nephropathy was prepared by two injections, and three experimental groups were set up: control group (n=8); adriamycin-induced nephropathy rat group (n=8); and Meprednisone (MP), Ciclosporin (CsA), and mycophenolate (MMF) treatment group (n=8). Twenty-four-hour urine protein was quantified and serum total protein (TP), albumin (ALB), cholesterol (Chol), triglyceride (TG), urea nitrogen (BUN), and serum creatinine (Scr) were measured by an automatic biochemical analyzer. Pathological changes in renal tissues were observed by light microscopy. Serum matrix metalloproteinase-2 (MMP-2), MMP-9, and transforming growth factor-β1 (TGF-β1) were evaluated by double-antibody sandwich enzyme-linked immunosorbent assay (ELISA). Connective tissue growth factor (CTGF) expression was measured by Western blotting. Expression of nephrin and podocin in podocytes was compared by immunohistochemistry and quantitative Real Time-Polymerase Chain Reaction (qRT-PCR). RESULTS Compared with the control group, 24-h urine protein in nephropathy group was significantly reduced at 2, 4, 8, and 12 weeks (p<0.01). Twenty-four-hour urine protein in the three treatment groups was significantly decreased compared with nephropathy group at 8 and 12 weeks (p<0.05). There were no significant differences among treatment groups (p>0.05), but their levels were higher than those in control group. TP and ALB levels in nephropathy group were decreased compared with control group (p<0.01) and increased compared with treatment groups (p<0.05), while TG and Chol levels in nephropathy group were increased compared with control group (p<0.01) and decreased compared with treatment group (p<0.05). There were no significant differences in biochemical parameters among the treatment groups. TGF-β1 levels were decreased, MMP-2 and MMP-9 levels were increased, and CTGF expression was reduced in the three therapeutic groups. Among the treatment groups, the combination of MP, CsA, and Rapa significantly inhibited fibrosis. The protein and mRNA levels of nephrin and podocin were significantly decreased in nephropathy group and their expression and distribution were partially restored in treatment groups. CONCLUSIONS The present findings suggest that the sequential therapeutic treatments based on the cell cycle significantly improved the pathological changes in adriamycin-induced nephropathy rats. The sequential treatments significantly reduced urine protein levels, increased TP, ALB, MMP-2, and MMP-9 levels, decreased TG, Chol, and TGF-β1 levels, restored expression of nephrin and podocin in renal tissues, and significantly improved renal fibrosis.

Abstract
AIMS The homeobox (HOX) genes function as transcriptional factors that can promote tumorigenesis. However, the expression profile of HOXA10 and the role this protein plays in solid tumors are unclear. Here we examined HOXA10 protein expression in samples from colorectal cancer (CRC) patients to address the clinical significance of this protein. MATERIALS AND METHODS Seven independent investigations from the Oncomine database were retrieved. A total of 85 patients who underwent radical excision followed by 5-fluorouracil (5-FU)-based adjuvant chemotherapy were enrolled. Immunohistochemistry was performed on pairs of cancerous and normal tissues to detect the expression of both HOXA10, and the phosphatase and tensin homolog deleted on chromosome ten (PTEN). Lentivirus-mediated RNA interference was used to knock down HOXA10 expression in LoVo and HT-29 cell lines, then cells' proliferation, apoptosis, and tumor growth in vivo were detected. RESULTS Oncomine data showed that HOXA10 expression was significantly upregulated in CRC tissues compared with relevant normal controls. In our study, 58 cases (68.2%) showed positive HOXA10 protein expression in tumor tissue and negative expression in normal tissues. HOXA10 protein upregulation was consistent with PTEN downregulation. Although not related to clinicopathological parameters, a significant correlation was found between HOXA10 upregulation and a decreased 5-year disease-free survival (DFS). A Cox proportional hazards model further suggested that HOXA10 overexpression was an independent factor to predict DFS of CRC patients. Furthermore, HOXA10 knockdown significantly increased sensitivity to 5-FU chemotherapy in vitro and in vivo. CONCLUSIONS Significant HOXA10 overexpression in CRC may be a potential biomarker indicating poor prognosis and 5-FU resistance.

Abstract
Records of the Ediacaran carbon cycle (635-541 million years ago) include the Shuram excursion (SE), the largest negative carbonate carbon isotope excursion in Earth history (down to -12‰). The nature of this excursion remains enigmatic given the difficulties of interpreting a perceived extreme global decrease in the δ13 C of seawater dissolved inorganic carbon. Here, we present carbonate and organic carbon isotope (δ13 Ccarb and δ13 Corg ) records from the Ediacaran Doushantuo Formation along a proximal-to-distal transect across the Yangtze Platform of South China as a test of the spatial variation of the SE. Contrary to expectations, our results show that the magnitude and morphology of this excursion and its relationship with coexisting δ13 Corg are highly heterogeneous across the platform. Integrated geochemical, mineralogical, petrographic, and stratigraphic evidence indicates that the SE is a primary marine signature. Data compilations demonstrate that the SE was also accompanied globally by parallel negative shifts of δ34 S of carbonate-associated sulfate (CAS) and increased 87 Sr/86 Sr ratio and coastal CAS concentration, suggesting elevated continental weathering and coastal marine sulfate concentration during the SE. In light of these observations, we propose a heterogeneous oxidation model to explain the high spatial heterogeneity of the SE and coexisting δ13 Corg records of the Doushantuo, with likely relevance to the SE in other regions. In this model, we infer continued marine redox stratification through the SE but with increased availability of oxidants (e.g., O2 and sulfate) limited to marginal near-surface marine environments. Oxidation of limited spatiotemporal extent provides a mechanism to drive heterogeneous oxidation of subsurface reduced carbon mostly in shelf areas. Regardless of the mechanism driving the SE, future models must consider the evidence for spatial heterogeneity in δ13 C presented in this study.

Abstract
This study explored the expression of interleukin 17D (IL-17D) secreted by human ovariancarcinoma cells and the effect of exogenous IL-17D transfection on MICA, which is the ligand of NKG2D, on the surface of ovary carcinoma cells. Human ovarian papillary serous adenocarcinoma cell line SKOV3, empty vector control cell line SKOV3/vector, exogenous human IL-17D stable-transfected cell line SKOV3/IL-17D, as well as cisplatin (CDDP)-resistant cell SKOV/CDDP were cultured; ovarian adenocarcinoma cell line OVCAR-3, empty vector control cell line OVCAR3/vector and OVCAE3/IL- 17D were observed under a microscope. In the study, methyl-thiazolyl-tetrazolium (MTT) method was used to detect the inhibition rate, resistance index and proliferation of SKOV3 and SKOV3/CDDP. It was found that the expression of IL-17 D in SKOV3/CDDP was much higher than that of its parent cell line SKOV3; IL-17D might be correlated to the drug resistance of cells; the proliferation of SKOV3 transfected with IL-17D was significantly accelerated, indicating IL-17D may be effective in promoting the growth of oncocyte.

Abstract
Mesothelial/monocytic incidental cardiac excrescence (MICE) is a rare and distinctive benign lesion often found during cardiac valve replacement. To date, 43 cases have been reported in the English literature. This lesion is important because of the potential for confusion with primary or metastatic malignancy. We report a case of MICE in a 47-year-old Chinese man with rheumatic heart disease whose MICE was discovered during mitral and aortic valve replacement. Histopathological examination of the lesion combined with immunohistochemistry confirmed the diagnosis of MICE.

Abstract
The aim of this study was to identify potential epigenetic prognostic biomarkers for colorectal cancer (CRC) in the Chinese population. The methylation status of five tumor suppressor genes (CDH13, DLEC1, FBLN3, hMHL1 and RUNX3) was determined using manual microdissection followed by methylation-specific PCR in 85 paired CRC specimens and adjacent normal tissue. The results showed that methylation frequencies in cancerous tissues were 31.8% for CDH13, 37.6% for DLEC1, 38.8% for FBLN3, 22.4% for hMHL1 and 27.1% for RUNX3, all of which were significantly higher than in corresponding normal tissue. Furthermore, CDH13 methylation was associated with poor differentiation (P = 0.019) and tended to be predominant in advanced stages (P = 0.084); FBLN3 methylation was associated with advanced stages (P = 0.027) and lymph node metastasis (P = 0.029). Accordingly, the methylation status of CDH13 (P = 0.022), FBLN3 (P = 0.008), CDH13 and/or FBLN3 (P = 0.001) predicted adverse overall survival in CRC, while hMHL1 methylation showed a protective role in survival (P = 0.046). Cox proportional hazard models further indicated that CDH13 and/or FBLN3 methylation, but not that of hMHL1, was an independent prognostic factor for CRC. In conclusion, we found CDH13 and FBLN3 gene methylation are potential biomarkers for poor prognosis in CRC.

Abstract
Biologics represent a large and growing segment of the therapeutic medicinal market. Sub-visible particles present in these products are a product quality attribute and a potential patient safety concern yet to be fully explored. Early and consistent particle quantitation and control throughout the product life cycle of these drugs from development to commercial lot release is critical in mitigating any concerns. This requires appropriate analytical methods which can be applied to biopharmaceuticals across a large variety of protein concentrations and modes of administration. The compendial light obscuration method for quantitating sub-visible particles in small volume parenterals is not ideally suited for therapeutic biologics. Approaches to modify the current compendial method so that it is applicable to biologics, including appropriate sample preparation, reduced assay sample volume, increased sizing information, and development of an appropriate sampling plan, are presented in this article. Successful applications of a modified light obscuration method to therapeutic protein products are demonstrated, and a strategy to utilise complimentary methods and techniques at different phases of product development is discussed.
