Can Mono- or Combination Therapy of Metformin with Cimetidine and Ibuprofen be a Promising Potential Therapy for Breast Cancer?
Metformin (MET), either alone or in combination with other drugs, has been considered a promising drug in cancer therapy. MET via activation of adenosine monophosphate-activated protein kinase (AMPK) signaling pathway and inhibiting the mammalian target of rapamycin (mTOR) mediates tumor proliferation. Moreover, as an antagonist of the histamine H2-receptor (H2R), cimetidine (CIM) is also attributed to several immune-stimulatory responses in non-immunogenic cancers.

Junctophilin-2 (JP2) is a key structural protein of junctional membrane complexes (JMCs) that stabilize contacts between the sarcoplasmic reticulum and transverse tubules required for excitation-contraction (EC) coupling in cardiomyocytes. Under pathophysiological conditions, the intracellular cysteine protease Calpain activated by disturbed intracellular Ca2+ homeostasis cleaves JP2 and, hence, disturbs EC coupling.J Cell Signal, 2022, Volume 3, Issue 4, p171-178 | DOI: 10.33696/Signaling.3.081
The MYCN oncoprotein has been notoriously undruggable and is infamous for causing aggressive cancer with poor outcomes in children and adults. Following surgery, radiation, and chemotherapy, patients who develop progressive disease have few treatment options. An analysis of the dysregulated protein network caused by MYCN amplification suggested co-targeting PLK1, AURKA, CKS1, AKT, MTOR, and USP7 would be useful to take advantage of synthetic lethal vulnerabilitiesJ Cell Signal, 2022, Volume 3, Issue 4, p179-192 | DOI: 10.33696/Signaling.3.082
Oxidative stress (OS) in the airway epithelium is associated with inflammation, cell damage, and mitochondrial dysfunction that may initiate or worsen respiratory disease. Redox regulation maintains the equilibrium of pro-oxidant/antioxidant reactions but can be disturbed by environmental exposures. The mechanism(s) underlying the induction and impact of OS on airway epithelium and how these influences on respiratory disease is poorly understood.J Cell Signal, 2022, Volume 3, Issue 4, p193-206 | DOI: 10.33696/Signaling.3.083
Resveratrol and Astaxanthin Protect Primary Human Nasal Epithelial Cells Cultured at an Air-liquid Interface from an Acute Oxidant Exposure
Oxidative stress (OS) in the airway epithelium is associated with cell damage, inflammation, and mitochondrial dysfunction that may initiate or worsen respiratory disease. However, it is unclear whether exogenous antioxidants can provide protection to the airway epithelium from OS. Resveratrol and astaxanthin are nutritional compounds that have shown diverse benefits including protection against OS and inflammation in various situations.J Cell Signal, 2022, Volume 3, Issue 4, p207-217 | DOI: 10.33696/Signaling.3.084
Cyclic Nucleotide Signaling Pathways in Apicomplexan Parasites Provide a Valuable Source for Novel Drug Targets
Malaria is one of the most important disabling human, tropical disease caused by different Plasmodium species, which are protozoan parasites belonging to the Apicomplexa. The Apicomplexan parasites have a plastid like structure the “apicoplast” and comprise the genera Plasmodium, Toxoplasma and Cryptosporidium causing malaria, toxoplasmosis, and cryptosporidiosis.

Breast cancer is the second most common cancer worldwide, affecting nearly one in eight women. Accurate cancer staging is essential for determining the patient’s prognosis and for choosing the appropriate treatment.
The last years have witnessed an increased interest in the genetic, epigenetic and transcriptional heterogeneity of mammalian hearts under basal and disease conditions. Although it is known for a long time that the heart consists of several, functionally different cell populations, more detailed insights into the potential heterogeneity of individual cell populations, such as cardiomyocytes, endothelial cells or fibroblasts were hindered by the lack of appropriate techniques.
Fatty acid oxidation disorders unfortunately can result in the sudden unexplained death of infants. Mitochondrial trifunctional protein (MTP) deficiency is one such disease where long-chain fatty acids cannot be fully oxidized through beta-oxidation which, can lead to cardiac arrythmias in an infant.
This commentary refers to our published article, as highlighted in this article most common gene causing breast cancer in the population living in the United Arab Emirates is BRCA2 followed by BRCA1. This is the first publication discussing about clinical and pathological features of breast cancer in woman with a positive genetic mutation in the United Arab Emirates.
Tyrosine kinase-type cell surface receptor HER2- targeted therapies have dramatically improved breast cancer patients’ outcome compared to conventional chemotherapies. In the clinic, HER2 monoclonal antibody trastuzumab with chemotherapy represent the gold standard treatment of HER2-positive breast cancer.
Breast Cancer is the most regularly diagnosed type of cancer in women in the world, making up on its own 25% of all cases, or nearly 2 million new cases in 2018, and 15% of all cancer related deaths, or around 626,700 deaths for that same year.
Dendorbium Nobile Lindl. Alkaloids Suppress NF-κB and NLRP3 Signaling Pathways to Attenuate Lipopolysaccharide-induced Neuroinflammation
The important immune cells in the brain are called microglia acting as the central junction between neuroinflammation and neurodegenerative diseases. In patients of cognitive disorders and Alzheimer’s disease (AD) animal models, amoebic morphology and inflammatory pathways are activated to release numerous cells in the inflammatory factors by active microglia.
Nausea and vomiting are protective defense mechanisms by which vomit competent species avoid ingestion of potentially toxic substances. More specifically, vomiting is the act of forceful expulsion of gastrointestinal contents through the mouth, whereas nausea is an unpleasant painless subjective feeling that one will imminently vomit.

At present, breast cancer is more frequently diagnosed in women than in men. According to global cancer statistics, each year more than 1,675,000 women are diagnosed and more than 500,000 of them die. Some subtypes of breast cancer have been described.
Worldwide, breast cancer is the most-common invasive cancer in women. Commonly used treatments include surgery, hormonal therapy, radiotherapy, chemotherapy and targeted therapy. Failure of these treatments is often due to intrinsic or acquired resistances and is responsible for most relapses of cancer . Heterogeneity among patients and tumors, together with the versatility of cancer make drug resistance more challenging to deal with.
Recently, Aras et al. reported that MNRR1, a nuclear DNA (nDNA)-encoded mitochondrial antigen, promotes cancer cell migration and the development of metastasis as a proof of concept supporting the participation of mitochondrial autoimmunity in breast carcinogenesis.

Breast cancer is the most common type of malignant tumor in women, accounting for 30% of women’s cancer, while the mortality rate ranks second among women’s cancer. Twenty-five percent of all breast cancer patients are premenopausal patients, and 7% of patients are younger than 40 years old.
Phosphoinositol 3 kinase (PI3K) defines a class of lipid kinases that have the ability to phosphorylate the inositol ring 3?-OH group in inositol phospholipids and therefore produce phosphatidylinositol (3,4,5)-trisphosphate (PIP3) . PI3K encompasses a family of enzymes divided into: Class IA PI3K which includes three isomers (?, ?, ?) and Class IB which include the group (?).
Protease-activated receptors (PARs) and the neurokinin 1 receptor (NK1R) belong to the G protein-coupled receptor (GPCR) family. In this review, we focus on the regulatory mechanism of ectodomain shedding by ADAM10/17 metalloprotease via GPCR signaling. PAR2 and NK1R induce membrane blebbing, resulting in phosphatidylserine externalization in the cellular membrane, which is required for ADAM10/17 metalloprotease activation. Membrane-embedded dual oxidase 2 (DUOX2) has NADPH oxidase and peroxidas
With increasing rates of obesity, rates of type 2 diabetes and diabetic complications are expected to rise exponentially over the next few decades (American Diabetic Association). A key feature of type 2 diabetes is a resistance to insulin. Insulin signaling is key to a number of physiological processes, including glucose metabolism, cell growth, general gene expression, and apoptosis.
