Savitzky-Golay filter based contrast-enhanced ultrasound quantification in hepatic tumors: Methodology and its correlation with tumor angiogenesis.

CONCLUSION: SGCQ software quantification have good consistency among three observers, the parameters of SGCQ can display the hemodynamics of HCC and MLT and the difference between them. AUC and EI can serve as useful biomarkers in tumor angiogenesis evaluation. PMID: 30103307 [PubMed - as supplied by publisher]

Authors: Song Q, An Q, Niu B, Lu X, Zhang N, Cao X Abstract MicroRNA-221/222 (miRNA-221/222, miR-221/222) is a noncoding microRNA which is widely distributed in eukaryotic organisms and deeply involved in the posttranscriptional regulation of gene expressions. According to recent studies, abnormal expressions of miR-221/222 are closely related to the occurrence and development of various kinds of malignant tumors. The role of miR-221/222 in tumor development and their potential molecular mechanism in various cancers, including liver cancer, colorectal cancer, cervical cancer, ovarian cancer, and endometrial carcino...

Somatic copy number alterations (CNAs) are a hallmark of cancer, but their role in tumorigenesis and clinical relevance remain largely unclear. Here we developed CNApp, a web-based tool that allows a comprehensive exploration of CNAs by using purity-corrected segmented data from multiple genomic platforms. CNApp generates genome-wide profiles, computes CNA scores for broad, focal and global CNA burdens, and uses machine learning-based predictions to classify samples. We applied CNApp to the TCGA pan-cancer dataset of 10,635 genomes showing that CNAs classify cancer types according to their tissue-of-origin, and that each c...

Cho Kim Fos-related-antigen-1 (Fra-1), a member of the activator protein-1 (AP-1) transcription factor superfamily, has an essential role in cancer progress and metastasis and Fra-1 is considered a therapeutic target in metastatic cancer including metastatic colorectal cancer (mCRC). However, its regulation at protein level has not yet been clearly elucidated. We found that ubiquitin-specific protease 21 (USP21) increases Fra-1 stability by deubiquitinating Fra-1 and enhances the expression of Fra-1 target genes in colon cancer cells. We also showed that USP21 controlled Fra-1-dependent migration and invasion acti...

Abstract It was well established that long non-coding RNAs (LncRNAs) could serve as oncogene or tumor suppressor in terms of the tumor type. FTX, as a member of lncRNA family, has been reported to be associated with several tumor progressions, such as hepatocellular carcinoma (HCC), renal cell carcinoma (RCC) and colorectal cancer. However, the regulatory role of FTX in osteosarcoma (OS) still lacks research analysis. This paper aims to explore how FTX exerts its regulatory role on OS by modulating TXNRD1/miR-320a, so as to provide a novel lncRNA theoretical framework for the diagnosis and treatment of OS. QRT-PCR...

Authors: Hou B, Li W, Li J, Ma J, Xia P, Liu Z, Zeng Q, Zhang X, Chang D Abstract Colorectal cancer (CRC) is the third most commonly diagnosed cancer and the fourth leading cause of cancer‑related mortality worldwide. Thus, identification of the mechanisms involved in the progression of CRC has become a crucial element of facilitating early CRC diagnosis and targeted therapy for patients with advanced CRC. Currently, Phospholysine phosphohistidine inorganic pyrophosphate phosphatase (LHPP), a type of histidine phosphatase protein, has been confirmed as a tumor suppressor in hepatocellular carcinoma (HCC) and cerv...

CONCLUSIONS This study was based on pharmacological networks results for the prediction of the multi-constituent, multi-target, and multi-pathway mechanisms of CKI, which might be a promising potential therapeutic and prevention candidate for anti-cancer. However, based on computer data mining and analysis, this study still needs to be further verified by in vivo/in vitro experiments, and the safety of CKI needs to be evaluated.

Publication date: March 2020Source: Biomedicine &Pharmacotherapy, Volume 123Author(s): Soudeh Ghafouri-Fard, Mohammadhosein Esmaeili, Mohammad TaheriAbstractH19 is a long non-coding RNA [lncRNA] which was firstly described as an oncofetal transcript. The imprinted gene is normally expressed from the maternal allele. However, this pattern of imprinting is dysregulated in several cancers leading to aberrant up-regulation of H19 in malignant tissues. Several studies have utilized this aberrant expression pattern to find specific biomarkers for detection of cancer in tumoral tissues or peripheral blood. Moreover, single nu...

This study aimed to obtain antitumor EPS and to optimize its production using different optimization approaches. Eighty EPSs-producing bacteria were obtained from mud samples. Isolate BS4 was selected as the most potent antitumor EPS-producer and identified as Bacillus mycoides BS4 using 16S rRNA gene sequence analysis. Cell viability and antitumor activity of produced EPS were investigated using microscopic examination and MTT assay. Interestingly, the produced EPS exhibited low cytotoxicity against normal cell baby hamster kidney (BHK) with IC50 at 254 μgml−1 while it exhibited an inhibitory effect against cance...
