REVIEW
Urmila Banik, Subramani Parasuraman, Arun Kumar Adhikary, Nor Hayati Othman
Worldwide breast cancer is the most common cancer in women. For many years clinicians and the researchers are examining and exploring various therapeutic modalities for breast cancer. Yet the disease has remained unconquered and the quest for cure is still going on. Present-day strategy of breast cancer therapy and prevention is either combination of a number of drugs or a drug that modulates multiple targets. In this regard natural products are now becoming significant options. Curcumin exemplifies a promising natural anticancer agent for this purpose...

AIMS: Poor efficacy of chemotherapy drugs in non-small-cell lung cancer (NSCLC) is the key reason for the failure of treatment, but the mechanism of this remains largely unknown. Stromal cell-derived factor 1-alpha (SDF-1α/CXCL12) is a small chemotactic cytokine protein that plays an important role in tumor progression. In this study, we investigated the anti-apoptotic mechanism of the CXCL12/CXCR4 axis in response to cisplatin, a commonly used chemotherapeutic drug, in human lung adenocarcinoma A549 cells...

Cytokines are key modulators of immunity. Most cytokines use the Janus kinase and signal transducers and activators of transcription (JAK-STAT) pathway to promote gene transcriptional regulation, but their signals must be attenuated by multiple mechanisms. These include the suppressors of cytokine signaling (SOCS) family of proteins, which represent a main negative regulation mechanism for the JAK-STAT pathway. Cytokine-inducible Src homology 2 (SH2)-containing protein (CIS), SOCS1, and SOCS3 proteins regulate cytokine signals that control the polarization of CD4(+) T cells and the maturation of CD8(+) T cells...

Proper regulation of lipid metabolism is critical for preventing the development of metabolic diseases. It is clear that leptin plays a critical role in the regulation of energy homeostasis by regulating energy intake. However, leptin can also regulate energy homeostasis by inducing lipolysis in adipocytes, but it is unclear how the major lipases are involved in leptin-stimulated lipolysis. Therefore, the objectives of this study were to determine if (1) leptin acts directly to induce lipolysis in bovine adipocytes, (2) the potential lipases involved in leptin-induced lipolysis in bovine adipocytes, and (3) increases translocation of adipose triglyceride lipase (ATGL) and hormone sensitive lipase (HSL) during leptin-stimulated lipolysis in bovine stromal vascular cell-derived adipocytes...

Signal transducer and activator of transcription (STAT) proteins are activated by phosphorylation in the spinal cord of patients suffering from amyotrophic lateral sclerosis (ALS). The major scope of our study is a comprehensive histological characterization of the mechanisms underlying neuronal and glial STAT3 activation in the pathogenesis of ALS using SOD1(G93A) mice. We calculated the fold changes (FCs, ratios vs. appropriate controls) of the numerical densities of the following phosphorylated STAT3-positive (pSTAT3)(+) cells: choline acetyltransferase (ChAT)(+) α-motoneurons, ionized calcium-binding adapter molecule 1 (Iba1)(+) microglia, and S100β(+) astrocytes in SOD1(G93A) mice...

Protein phosphorylation, mediated by protein kinases, has important physiological and pathological implications in our lives . Targeting kinase is one of the most interesting of the emerging topics in the pharmaceutical industry, especially since there is a focus on cancer therapy. Given that kinases may be involved in the aging process the focus will be on using the kinase inhibitor for anti-aging intervention to enhance healthspan and increase longevity. In this review , we will summarize: (i) the impact of the phosphoproteomic approach to elucidate molecular mechanisms of diseases; (ii) importance of the drug discovery approach for targeting kinases; (iii) the dysregulation of Janus kinase (JAK) / signal-transducing adapter molecules (STAT) and p70 ribosomal protein S6 kinase (S6Ks) pathway in aging and the age-related process; (iv) the epidemiological studies available in order to see whether a correlation between JAK/STAT and S6Ks mRNA expression levels exist in cancer and in patient outcome; (v) finally, we will show selected inhibitors of these kinases approved by the US Food and Drug Administration (FDA)...

In recent years, abnormal RNA editing has been shown to play an important role in the development of esophageal squamous cell carcinoma, as such abnormal editing is catalyzed by ADAR (adenosine deaminases acting on RNA). However, the regulatory mechanism of ADAR1 in esophageal squamous cell carcinomas remains largely unknown. In this study, we investigated ADAR1 expression and its association with RNA editing in esophageal squamous cell carcinomas. RNA sequencing applied to esophageal squamous cell carcinoma clinical samples showed that ADAR1 expression was correlated with the expression of STAT1, STAT2, and IRF9...

Previous studies have suggested that the Janus kinase (JAK)/signal transducers and activators of transcription (STAT) pathway is involved in hyperglycemia‑induced lung injury. The present study aimed to investigate the roles of suppressor of cytokine signaling3 (SOCS3) in the regulation of JAK2/STAT3 activation following high glucose (HG) treatment in A549 human pulmonary epithelial cells. Cell viability was evaluated using Cell Counting Kit-8 and lactate dehydrogenase assays. HG‑induced inflammatory injury in A549 cells was assessed through the evaluation of interleukin‑6 (IL‑6) and tumor necrosis factor‑α (TNF‑α) levels using ELISA...

Early extubation is increasingly common in congenital heart surgery, but there are limited outcomes data across the spectrum of case complexity. We performed a retrospective review of 201 pediatric operations using cardiopulmonary bypass between 2012 and 2014. Patients extubated in the operating room or immediately on arrival to the ICU were compared to those extubated by traditional protocols. In-hospital mortality, major complications, need for re-intubation, hospital length of stay, and chest-tube days were compared between groups and by Society of Thoracic Surgeons-European Association for Cardiothoracic Surgery Congenital Heart Surgery (STAT) mortality category...

Endobronchial ultrasound (EBUS)-guided transbronchial needle aspiration (TBNA) is currently the modality of choice for evaluation of mediastinal lymphadenopathy. However, there is still uncertainty regarding the training methodology and the number of procedures required to attain proficiency in EBUS. Herein, we performed a systematic review of studies selected from PubMed, EmBase and Scopus databases describing the training and assessment of proficiency during EBUS, specifically studies investigating various methods for training, its outcome and the number of procedures required to overcome the learning curve for EBUS...

Teleost fins can regenerate accurate position-matched structure and function after amputation. However, we still lack systematic transcriptional profiling and methodologies to understand the molecular basis of fin regeneration. After histological analysis, we established a suppression subtraction hybridization library containing 418 distinct sequences expressed differentially during the process of blastema formation and differentiation in caudal fin regeneration. Genome ontology and comparative analysis of differential distribution of our data and the reference zebrafish genome showed notable subcategories, including multi-organism processes, response to stimuli, extracellular matrix, antioxidant activity, and cell junction function...

The disease-free survival following radiotherapy is often limited by the development of second/secondary cancers. This significant impediment to effective cancer treatment implicated even in the modern-day radiotherapy needs to be countered effectively. Critical analysis reveals that besides achieving effective tumor control, radiotherapy elicits certain cellular and systemic inflammatory events in tumor infiltrate, which remain relatively stable and tend to facilitate "in-field" or "out of field" oncogenesis in due course of time...

BACKGROUND: Our health system orders a high number of STAT priority portable chest radiographs (62%) compared to Routine (35%) and Today (3%). Retrospective chart review of 1000 chest radiographs ordered with the STAT priority revealed that 38% of studies did not indicate clinical urgency. Given the high number or STAT priority portable chest radiographs ordered, prioritizing acquisition and interpretation of true STATs has become challenging for technologists and radiologists, leading to process inefficiencies, long turnaround times (TATs), communication failures, and patient-safety errors...

INTRODUCTION: Chronic hepatitis C (CHC) is a major cause of liver disease worldwide which often leads to progressive liver inflammation, fibrosis, cirrhosis and hepatocellular carcinoma (HCC). CHC displays heterogeneous progression depending on a broad set of factors, some of them intrinsic to each individual such as the patient's genetic profile. This study aims to evaluate the contribution of certain genetic variants of crucial interferon alpha and lambda signaling pathways to the hepatic necroinflammatory activity (NIA) grade of CHC patients...
