Abstract Aim To observe the effect of propranolol in cervical cancer and investigate the mechanism of the effect. Methods and Results We found 5 direct protein targets (DPTs) of propranolol (PRO) by DrugBank5.0 firstly. Next, we analyzed protein-protein interaction (PPI) network and Kyoto Encyclopedia of Genes and Genomes (KEGG) pathways of PRO DPTs and the result showed that PRO was linked with cGMP/PKG pathway. Then, we recognized the top 38 upexpressed genes of cervical cancer (CC) based original microarray datasets (GSE7803, GSE9750, GSE39001 and GSE63514). Further, we analyzed the biological process with the 38 overexpressed genes by STRING. We found some of overexpressed genes of CC participated in GMP biosynthetic process. Lastly, the function of PRO in CC was validated by MTT assay, Western blotting, flow cytometry and colony formation assay methods. We verified PRO can suppress cGMP/PKG pathway then inhibits CC cell growth. Conclusion The bioinformatical analysis combine with traditional experiment can help us understanding potential molecular mechanism about how PRO acting in CC. This method is a new paradigm which can guide future researches about mechanism in existing diseases and drugs.

A system-wide understanding of cellular function requires knowledge of all functional interactions between the expressed proteins. The STRING database aims to collect and integrate this information, by consolidating known and predicted protein-protein association data for a large number of organisms. The associations in STRING include direct (physical) interactions, as well as indirect (functional) interactions, as long as both are specific and biologically meaningful. Apart from collecting and ...

Human papillomavirus (HPV) has been identified as a necessary factor in the development of pre-invasive and invasive cancers of the lower genital tract, of which cervical cancer is the most prevalent. A molecular understanding of malignant transformation and epidemiologic information has led to the development of many strategies for detection and early intervention. Newer tests for oncogenic subtypes of HPV have made it possible to predict the risk of future development of cervical cancer. This ...

Abstract Colon cancer is the fourth and third most common cancer, respectively in men and women worldwide and its incidence is on the increase. Stress response has been associated with the incidence and development of cancer. The catecholamines (CA), adrenaline (AD) and noradrenaline (NA), are crucial mediators of stress response, exerting their effects through interaction with α- and β-adrenergic receptors (AR). Colon cancer cells express β-AR, and their activation has been implicated in carcin...

Abstract HPV viruses are integral to the development of cervical cancer. The pathogenesis has been extensively studied. To date, numerous HPV tests and products have been developed and successfully utilized in diagnosis, treatment and prevention of cervical cancer. The HPV DNA test, when combined with other routine cervical cancer screening and diagnostic tests namely exfoliative cytology, visual inspection with acetic acid (VIA) and colposcopy has increased the detection rate of cervical cancer...

The many functional partnerships and interactions that occur between proteins are at the core of cellular processing and their systematic characterization helps to provide context in molecular systems biology. However, known and predicted interactions are scattered over multiple resources, and the available data exhibit notable differences in terms of quality and completeness.

Background: Resveratrol increases nitric oxide (NO) production via increased expression and activation of endothelial-form-NO-synthase (eNOS) in endothelial cells. However, the role of downstream cGMP/protein kinase G (PKG) signaling, a pathway activated by NO/eNOS, in pro- and anti-angiogenic effects of resveratrol is still unclear. Materials and Methods: Endogenous NO/cGMP/PKG pathway and downstream cell-survival proteins (Inhibitor of Apoptosis Proteins, IAPs) were studied in relation to pro-...

ABSTRACT Cytology-based nation-wide cervical screening has led to a substantial reduction of the incidence of cervical cancer in western countries. However, the sensitivity of cytology for the detection of high-grade precursor lesions or cervical cancer is limited; therefore, repeated testing is necessary to achieve program effectiveness. Additionally, adenocarcinomas and its precursors are often missed by cytology. Consequently, there is a need for a better screening test. The insight that infe...

Aim: The present study aimed to elucidate the effect of CTCF on renal interstitial fibrosis in chronic kidney disease (CKD) and underlying mechanisms. Materials & methods: We measured NPHS2 expression and investigated its function in a unilateral ureteral obstruction-induced mouse model of CKD. Results: NPHS2 was poorly expressed in CKD mice. miR-185-5p targeted NPHS2 and reduced its expression, leading to increased α-SMA and COL I/III expression, increased renal interstitial fibrosis area and e...
Recently, the use of already-approved drugs for new or alternative treatments has been a beneficial, although challenging endeavor in medicine. New drug applications approvals by the FDA are registered to target specific diseases, offering a contribution to treat specific pathologies for a particular group of patients. Nevertheless, most drugs have intricate mechanisms of action and hence, their effects are not usually restricted to one organ or one disease. Diverging from its original intent of...

Helicobacter pylori (H. pylori) is listed as a class I carcinogen in human gastric cancer; however, the underlying mechanisms are poorly understood. In this study, we identified Protogenin (PRTG) was upregulated in both gastric cancer tissues and H. pylori-infected tissues by analyzing dysregulated genes in TCGA and GEO databases. Importantly, upregulated PRTG predicted poor prognosis of gastric cancer patients and integrative analysis revealed that PRTG served as an oncogenic protein in gastric...

BACKGROUND: Aldrichina grahami (Diptera: Calliphoridae) is a forensically important fly, which has been widely applied to practical legal investigations. Unlike other necrophagous flies, A. grahami exhibits cold tolerance which helps to maintain its activity during low-temperature months, when other species are usually not active. Hence, A. grahami is considered an important forensic insect especially in cold seasons. In this study, we aim to explore the molecular mechanisms of cold tolerance of...
