Esophageal cancer is a common gastrointestinal tumor, with high incidence in our country. Histone demethylase 4 plays an important role in chromosome structural modification and gene expression regulation, becoming a new target for tumor treatment. GASC1 is an important member of the KDM4 family, closely related to the malignancy of tumors.

Constructing the short hairpin interfering RNA plasmid and blank control plasmid of gene KDM4C (also known as GASC1), transfecting them into human esophageal squamous cell carcinoma cell lines (KYSE-150 and KYSE-30, respectively), and screening the best treatment concentration based on cell viability. Cell cloning experiments analyzed the proliferation characteristics of each group of cells. Cell migration and scratch healing experiments analyzed the tumor's malignant metastasis and invasion capabilities. Immunofluorescence analysis was used to test the expression characteristics of protein GASC1. Western blot was used to analyze protein Notch1, HIF1A, Flt-1, c-myc, c-gnant development.
Thymosin b10 (TMSB10), a member of the thymosin family, is mainly located in cells and participates in the assembly and occurrence of cytoskeleton. We aimed to investigate the regulatory mechanism of TMSB10 in ccRCC.

In this study, Xiantao Academic Tools were taken to perform the pan-cancer expression and immune infiltration analysis of TMSB10. Furthermore, it is found that there is a binding site for JUN in the promoter region of TMSB10 through the JASPAR database predictive analysis. The CHIP experiment is used to confirm that JUN regulates the expression of TMSB10 through transcription, and to further detect the mRNA expression level of TMSB10 and JUN in ccRCC cell lines by qRT-PCR. TJ-M2010-5 inhibitor Proliferation and apoptosis function analysis was also carried out to determine the functional changes of ccRCC cell lines after the expression of TMSB10 was regulated by JUN transcription.

The results show that TMSB10 is significantly up-regulated in a variety of cancers. Moreover, JUN regulates the high expression of TMSB10 through transcription and further promotes the proliferation of ccRCC cells and inhibits their apoptosis.

In conclusion, this study shows that JUN transcription regulates the high expression of TMSB10 and promotes the progress of ccRCC.

It has been demonstrated
that acetylsalicylic acid (ASA) treatment halves hepatitis C virus (HCV) expression in hepatocarcinoma cells. However, the signaling pathway that promotes this ASA-induced antiviral effect has not yet been identified.

The aim of this work was to identify alterations in the transcriptional profile of Huh-7-HCV-subgenomic replicon cells with vs. without ASA treatment. This comparison sheds light onto the signaling pathways and molecular mechanisms involved in the antiviral effects of ASA.

Human hepatocellular carcinoma (Huh-7) cells that express non-structural HCV proteins (Huh-7-HCV-replicon cells) were exposed to 4 mM ASA for 0, 24, 48, and 72 hours. Total RNA was isolated, and cDNA was synthesized. Transcripts were then tagged with biotin and purified. Thereafter, they were fragmented and hybridized on HG-U133 Plus 2 Gene Expression chips. Hybridization signals were captured using a GeneChip 3000 7G Scanner and analyzed via Expression Console and dChip Software.

When exposed to ASA, hepatocarcinoma cells with non-structural HCV proteins were found to differentially regulate genes with oxidative roles in the cell. The most upregulated genes were interleukin 8 (IL-8), cytochrome P450 (CYP450), and metallothioneins (MTs), while the most downregulated genes were ribonucleotide reductases (RRs).

These results show that ASA modulates the expression of genes with antioxidant functions. This suggests that ASA induces a remodeling of the antioxidant microenvironment, which may in turn interfere with the replication of HCV.

This study aims to investigate how miR-561-5p regulated the expression of RAC1 and whether its effects on RAC1 was associated with the proliferation, migration, invasion, and apoptosis in pancreatic ductal adenocarcinoma (PDAC) cells.

RT-qPCR was performed to assess miR-561-5p expression in human PDAC tissues. A series of
experiments including cell counting Kit-8, colony formation, cell migration and invasion, and apoptosis assays were used to assess the PDAC cell biological behaviors. TargetScan v7.2 was used to identify the miR-561-5p target genes, dual-luciferase reporter assay was performed to confirm the targeted relationship between miR-561-5p and Rac family small GTPase 1 (RAC1). Also, RAC1 was upregulated in miR561-5p overexpressed PDAC cells to evaluate the functional involvement of RAC1 in miR-561-5p mediated PDAC cell proliferation and invasion.

The results demonstrated that miR-561-5p expression was lower in PDAC tissues compared with in normal tissues. Overexpression of miR-561-5p inhibited PDAC cell proliferation, migration, and invasion, and promoted apoptosis in vitro, while miR-561-5p-knockdown had the opposite effects in the PDAC cell line BxPC3. Using bioinformatics analysis and dual-luciferase reporter assays, the present study revealed that RAC1 was a direct target of miR-561-5p and that RAC1 overexpression could partly rescue the suppressive effects of miR-561-5p mimics on PDAC cells.

The overexpression of miR-561-5p may suppress carcinogenesis in PDAC cells by targeting RAC1 and inhibit PDAC cell proliferation and invasion.

To uncover the expression of Lamins B2 (LMNB2) in tumor tissues and the effects on the progression of esophageal cancer.

IHC assays were performed to detect the expression of LMNB2 in esophageal cancer tissues. Kaplan-Meier survival analysis was performed to confirm its effects on patients' prognosis. Colony formation, MTT, and Immunoblot assays were performed to confirm its effects on cell growth, and FCM assays were performed to show its effects on apoptosis. Tumor growth assays were conducted to assess the effects of LMNB2 on esophageal cancer progression in mice.

LMNB2 expression was associated with the prognosis of esophageal cancer patients. Further in vitro and in vivo assays were performed and showed that LMNB2 was involved in the regulation of cell proliferation in esophageal cancer. Additionally, LMNB2 depletion contributed to the apoptosis of esophageal cancer cells. In conclusion, we demonstrate LMNB2 affects the development of esophageal cancer by promoting cell proliferation and inhibiting apoptosis.

This study showed the involvement of LMNB2 in esophageal cancer progression in vitro and in vivo, and provides a novel therapeutic target for esophageal cancer.

Prostate cancer is one of the most frequently diagnosed cancer in men and ranks as the second most common cause of cancer-related deaths in developed countries. HN1 is a highly expressed gene in prostate cancer and controls the levels of several cell cycle regulatory proteins including Cyclin B1. Cyclin B1 is a cell cycle control protein but is also involved in Docetaxel and 2-Methoxyestradiol induced apoptosis. Since Cyclin B1 level may affect chemotherapy success and HN1-Cyclin B1 negative correlation has already been shown, so in this study, we investigated the possible role of HN1 in chemotherapeutic resistance in prostate cancer cells.

Androgen-dependent and independent prostate cancer cells were used in the study. A full-length human HN1 cDNA fragment was cloned to a mammalian expression vector and this construct was used for overexpression experiments. A siRNA that specifically targets HN1 was used for HN1 depletion experiments. Evaluation of apoptosis was performed by the level of PARP cleavage and an apoptosis kit that measure Caspase 3 activity.

The HN1 protein level is decreased in the Docetaxel or 2-Methoxyestradiol treated LNCaP and PC-3 PCa cells whereas the Cyclin B1 level is increased. HN1 overexpression inhibited Docetaxel and 2-Methoxyestradiol induced apoptosis. In concordance, its depletion further stimulated apoptosis in drug-treated cells. However, silencing of Cyclin B1 along with HN1 abolished the increased apoptotic response induced by silencing of HN1 in Docetaxel or 2-Methoxyestradiol treated cells.

HN1 is an anti-apoptotic molecule and inhibits Docetaxel and 2-Methoxyestradiol induced apoptosis by targeting Cyclin B1.

This study was designed to visualize the pan-cancer prognostic significance of PReferentially expressed Antigen in Melanoma (PRAME) and investigate the relationship between PRAME expression and tumor immunity.

We explored the expression patterns and prognostic value of PRAME across multiple cancers using data from the Cancer Genome Atlas, Genotype-Tissue Expression, and Cancer Cell Line Encyclopedia databases. Spearman's correlation test was used to evaluate correlations between PRAME expression and the tumor immune microenvironment, mutation indicators, and DNA methylation. Finally, the functions of PRAME and potential signaling pathway mechanisms were explored through Gene Set Enrichment Analysis (GSEA).

Pan-cancer survival analysis indicated that PRAME was widely up-regulated in most tumors, and its high expression was indicative of poor overall survival in different cancer types. In addition, PRAME expression levels were strongly linked to immune infiltration, immune score, immune checkpoint, immune neoantigens, tumor mutation burden, microsatellite instability, mismatch repair, and DNA methyltransferase in a variety of cancers. GSEA analysis revealed that PRAME was related to the regulation of numerous signaling pathways implicated in tumor immunity and tumorigenicity.

PRAME has the potential to serve as a prognostic pan-cancer biomarker and is correlated with tumor immunity. Its use may help shed light on optimum cancer therapies.

In patients with early Lyme disease (ELD), cardiac involvement is known to occur in approximately 1% of patients. We measured high-sensitivity troponin T (hsTnT) in patients with early Lyme disease to evaluate the possibility of subclinical cardiac involvement.

We measured hsTnT in 41 patients with well characterized ELD.

A total of 6/41 (14.6%) of patients exhibited hsTnT values above either the gender specific or gender neutral 99
percentile cutoff for a normal hsTnT. One patient had a value greater than the cutoff used for acute myocardial infarction.

There are many possible explanations for increased hsTnT values in different types of patients in the absence of acute cardiac damage. Nonetheless our results raise the possibility that subclinical cardiac involvement may be more common in ELD than previously recognized. Further studies will be necessary to elucidate the significance of this finding.
