Inositol polyphosphate 5-phosphatases act on inositol phosphates and phosphoinositides as substrates. They are 10 different isoenzymes and several splice variants in the human genome that are involved in a series of human pathologies such as the Lowe syndrome, the Joubert and MORM syndromes, breast cancer, glioblastoma, gastric cancer and several other type of cancers. Inositol 5-phosphatases can be amplified in h Read More

The development of targeted therapy drugs acting on tumor growth and progression is greatly expanding these last years. Among them kinase inhibitors have a prominent position and have demonstrated efficacy and clinical benefits in solid and hematologic malignancies. Compared to conventional systemic cytotoxic chemotherapeutic agents, their specific mechanism of action limits the occurrence of adverse events. Read More

Hematopoietic and mesenchymal stem and progenitor cells are organized in the osteo-hematopoietic niche, a complex microenvironment ensuring self-renewal and differentiation. Perturbations of the niche architecture, the mutual cellular interactions and signaling pathways disrupt tissue homeostasis resulting in cytopenia and malignant diseases such as myelodysplastic syndromes (MDS), supporting the concept of niche-i Read More

Splicing is an essential cellular process which is carried out by the spliceosome in order to remove the introns and join the exons present in pre-mRNA transcripts. A variety of spliceosomal mutations have been recently identified in the myelodysplastic syndromes (MDS), a heterogeneous group of hematopoietic stem cell malignancies, revealing a new leukemogenic pathway involving spliceosomal dysfunction. Splicing fact Read More

Nuclear phosphoinositide-phospholipase C (PI-PLC) beta1 plays a crucial role in the molecular steps that regulate cell proliferation and differentiation in several experimental models, such as myoblasts and hematopoietic cells, via interaction with other important molecular players. Indeed, PI-PLCbeta1 and its related molecules are definitely involved in hematopoiesis, and particularly in drug-induced myeloid or eryth Read More

Myelodysplastic syndromes (MDS) are a heterogeneous group of hematologic diseases, mainly affecting the elderly, characterized by unilinear or multilinear peripheral cytopenia, bone marrow ineffective haemopoiesis, and a varying risk of progression to acute myeloid leukemia (AML). On the basis of the prognostic score systems currently used, MDS patients are generally classified as having higher risk (HR) or lower risk (LR) Read More

The roles of the epidermal growth factor receptor (EGFR) signaling pathway in various cancers including breast, bladder, brain, colorectal, esophageal, gastric, head and neck, hepatocellular, lung, neuroblastoma, ovarian, pancreatic, prostate, renal and other cancers have been keenly investigated since the 1980’s. While the receptors and many downstream signaling molecules have been identified and characterized, t Read More

Psychological stress is an emotion experienced when people are under mental pressure or encounter unexpected problems. Extreme or repetitive stress increases the risk of developing human disease, including cardiovascular disease (CVD), immune diseases, mental disorders, and cancer. Several studies have shown an association between psychological stress and cancer growth and metastasis in animal models and case s Read More

Objectives:-To examine the effect of nicotine (Ni) on bone socket healing treated with Ellagic acid (EA) after tooth extraction in rat. Materials and Methods: Thirty-Two Sprague Dawley (SD) male rats were divided into four groups. The group 1 was administrated with distilled water intragastrically and injected sterile saline subcutaneously. The group 2 was administrated with EA orally and injected with sterile saline s Read More

Despite advances in understanding the pathophysiology of Alzheimer’s disease (AD), its therapy remains largely symptomatic and supportive. Acetylcholinesterase inhibitors - the first-line drugs used today do not prevent and treat AD. So far, over 90 Phase 3 trials of AD have been unsuccessful with 99.0% failure rate. There is, therefore, an urgent need to find effective new therapies for AD. Owing to the multifactor Read More

Multiple pathogenic mechanisms contribute to the development of colorectal cancer. This tumor is characterized by high chemoresistance and low immunogenicity due to the effective mechanisms of immunosuppression. Dendritic cells (DCs) play a key role in recognition of tumor antigens and induction of T-cell-primed anticancer response. However, in cancer microenvironment, the function of tumor-infiltrating DCs becomes i Read More

Gluten intolerance is an umbrella term for gluten-related disorders manifested in health decline as a result of the gluten ingestion. The spectrum of gluten-related disorders includes three major groups: autoimmune (mainly, Celiac Disease, CD, also known as Celiac Sprue, dermatitis herpetiformis, or gluten-sensitive ataxia), allergic (wheat allergy, WA), and non-autoimmune non-allergic (non-celiac gluten sensitivity, N Read More
