Unlocking Novel Therapeutic Potential of Angiotensin II Receptor Blockers.

Pharmaceutical companies keep producing novel drugs and drug treatments for improving the life of every sick individual, most often following a pattern; a specific drug for a specific condition. Evidence suggests that different medications can have a positive effect on different pathological conditions. The full potential of existing therapies can be revealed through drug repurposing-also referred to as drug repositioning, reprofiling, or re-tasking-which involves identifying new therapeutic uses for approved or investigational drugs beyond their original indications. One significant target in

Role of exosomes in pancreatic cancer.

Pancreatic cancer is one of the most lethal malignancies. Exosomes, which are released by multiple cell types, such as cancer cells, contain functional biomolecules (including proteins, nucleic acids and lipids) that can be horizontally delivered to recipient cells. Exosomes act as the most prominent mediator of intercellular communication and can regulate, instruct and re-educate their surrounding microenvironment and target specific organs. The present review performed an extensive search of multiple databases from 2005 to April 23 2017, for eligible literature relating to exosomes and their

Recent Developments and Evolving Therapeutic Strategies in KMT2A-Rearranged Acute Leukemia.

BackgroundRearrangements of the histone-lysine-N-methyltransferase (KMT2A), previously referred to as mixed-lineage leukemia (MLL), are among the most common chromosomal abnormalities in patients with acute myeloid leukemia (AML) and acute lymphoblastic leukemia (ALL), involving numerous different fusion partners. KMT2A-rearranged (KMT2A-r) leukemia is characterized by a rapid onset, aggressive progression, and significantly worse prognosis compared to non-KMT2A-r leukemias. Even with contemporary chemotherapeutic treatments and hematopoietic stem cell transplantations (HSCT), patients with KM

Mitochondrial Dysfunction in Chemotherapy-Induced Peripheral Neuropathy (CIPN).

The mitochondrial dysfunction has a critical role in several disorders including chemotherapy-induced peripheral neuropathies (CIPN). This is due to a related dysregulation of pathways involving calcium signalling, reactive oxygen species and apoptosis. Vincristine is able to affect calcium movement through the Dorsal Root Ganglia (DRG) neuronal mitochondrial membrane, altering its homeostasis and leading to abnormal neuronal excitability. Paclitaxel induces the opening of the mitochondrial permeability transition pore in axons followed by mitochondrial membrane potential loss, increased react

Выборочное ингибирование TLR2 стимулирует созревание олигодендроглиевых клеток потомства до олигодендроцитов.

Важно описать новые технологии для преодоления барьера и поощрения ремиелионации, поскольку многие аксоны остаются демиелиномированными в CNS пациентов с множественным склерозом (MS). Недавние исследования показывают, что LR2 является негативным регулятором созревания олигодендроглиевых клеток потомства (OPC) до олигодендроцитов (OLs) и что TLR2 присутствует в хронических повреждениях MS человека. Однако до недавнего времени не существовало конкретного ингибитора TLR2. Поэтому мы создали пептид, соответствующий TLR2-interacting Домена MyD88 (TIDM), которая конкретно препятствует TLR2, но не др

The Glycocalyx and Its Role in Vascular Physiology and Vascular Related Diseases.

PurposeIn 2007 the two senior authors wrote a review on the structure and function of the endothelial glycocalyx layer (Weinbaum in Annu Rev Biomed Eng 9:121-167, 2007). Since then there has been an explosion of interest in this hydrated gel-like structure that coats the luminal surface of endothelial cells that line our vasculature due to its important functions in (A) basic vascular physiology and (B) vascular related diseases. This review will highlight the major advances that have occurred since our 2007 paper.MethodsA literature search mainly focusing on the role of the glycocalyx in the

IRF4 Enhances Radiosensitivity of Cervical Cancer by Inhibiting the PI3K/Akt/mTOR Pathway to Regulate Autophagy.

Interferon regulatory factor 4 (IRF4), a critical member of the IRF transcription factor family, harbors an elusive biological role in cervical cancer. Through immunohistochemical staining and immunoblotting, CCK-8 viability assays, EdU incorporation tests, clonogenic survival experiments, flow cytometric detection, transmission electron microscopy, immunofluorescence staining and heterotopic transplantation model, we discover that IRF4 expression was markedly decreased in cervical cancer tissues and cell lines compared to normal controls. Overexpression of IRF4 suppressed proliferation, migra

Catgut embedding in acupoints combined with repetitive transcranial magnetic stimulation for the treatment of postmenopausal osteoporosis: study protocol for a randomized clinical trial.

BACKGROUND: To date, the clinical modulation for bone metabolism based on the neuro-bone mass regulation theory is still not popular. The stimulation of nerve systems to explore novel treatments for Postmenopausal osteoporosis (PMOP) is urgent and significant. Preliminary research results suggested that changes brain function and structure may play a crucial role in bone metabolism with PMOP. Thus, we set up a clinical trial to investigate the effect of the combination of repetitive transcranial magnetic stimulation (rTMS) and catgut embedding in acupoints (CEA) for PMOP and to elucidate the c

Genetic Polymorphisms Associated with Vincristine Pharmacokinetics and Vincristine-Induced Peripheral Neuropathy in Pediatric Oncology Patients.

Vincristine (VCR) is an important component of curative chemotherapy for many childhood cancers. Its main side effect is VCR-induced peripheral neuropathy (VIPN), a dose limiting toxicity. Some children are more susceptible to VIPN, which is at least partially dependent on genetic factors and pharmacokinetics (PK). In this study, we identify and replicate genetic variants associated with VCR PK and VIPN. Patient samples from a randomized clinical trial studying the effect of administration duration of VCR on VIPN in 90 patients were used. PK sampling was conducted on between one and five occas

A Triazaspirane Derivative Inhibits Migration and Invasion in PC3 Prostate Cancer Cells.

Cancer is a serious health problem due to the complexity of establishing an effective treatment. The purpose of this work was to evaluate the activity of a triazaspirane as a migration and invasion inhibitor in PC3 prostatic tumor cells through a possible negative regulation of the FAK/Src signal transduction pathway and decreased secretion of metalloproteinases 2 and 9. Molecular docking analysis was performed using Moe 2008.10 software. Migration (wound-healing assay) and invasion (Boyden chamber assay) assays were performed. In addition, the Western blot technique was used to quantify prote

The role of autophagy in cancer: from molecular mechanism to therapeutic window.

Autophagy is a cellular degradation process that plays a crucial role in maintaining metabolic homeostasis under conditions of stress or nutrient deprivation. This process involves sequestering, breaking down, and recycling intracellular components such as proteins, organelles, and cytoplasmic materials. Autophagy also serves as a mechanism for eliminating pathogens and engulfing apoptotic cells. In the absence of stress, baseline autophagy activity is essential for degrading damaged cellular components and recycling nutrients to maintain cellular vitality. The relationship between autophagy a

Alzheimer's Disease: Cellular and Pharmacological Aspects.

Alzheimer's disease was described more than 100 years ago and despite the fact that several molecules are being tested for its treatment, which are in phase III trials, the disease continues to progress. The main problem is that these molecules function properly in healthy neurons, while neuronal pathology includes plasma membrane disruption, malfunction of various organelles, and hyperphosphorylation of Tau and amyloid plaques. The main objective of this article is the discussion of a neuronal restoration therapy, where molecules designed for the treatment of Alzheimer's disease would probabl

Deregulation of the EGFR/PI3K/PTEN/Akt/mTORC1 pathway in breast cancer: possibilities for therapeutic intervention.

The EGFR/PI3K/PTEN/Akt/mTORC1/GSK-3 pathway plays prominent roles in malignant transformation, prevention of apoptosis, drug resistance and metastasis. The expression of this pathway is frequently altered in breast cancer due to mutations at or aberrant expression of: HER2, ERalpha, BRCA1, BRCA2, EGFR1, PIK3CA, PTEN, TP53, RB as well as other oncogenes and tumor suppressor genes. In some breast cancer cases, mutations at certain components of this pathway (e.g., PIK3CA) are associated with a better prognosis than breast cancers lacking these mutations. The expression of this pathway and upstre

Current landscape and future directions of targeted-alpha-therapy for glioblastoma treatment.

Glioblastoma (GB) is the most aggressive malignancy of the central nervous system. Despite two decades of intensive research since the establishment of the standard of care, emerging strategies have yet to produce consistent satisfactory outcomes. Because of its specific localisation and intricate characteristics, GB is a uniquely regulated solid tumour with a strong resistance to therapy. Advances in targeted radionuclide therapy (TRT), particularly with the introduction of a-emitting radionuclides, have unveiled potential avenues for the management of GB. Recent preclinical and clinical stud

The Transcription Axes ERK-Elk1, JNK-cJun, and JAK-STAT Promote Autophagy Activation and Proteasome Inhibitor Resistance in Prostate Cancer Cells.

The rapid emergence of resistance limits the application of proteasome inhibitors against solid tumors, despite their effectiveness in the treatment of hematological malignancies. Resistant phenotypes are complex and multifaceted, and, thus, the mechanisms involved have not been adequately described. In this study, a Bortezomib-resistant prostate cancer cell line is created by using the PC-3 cell as a prostate carcinoma model of high metastatic potential. The main biochemical differences and adaptations exhibited by the resistant cells revolve around apoptosis evasion, autophagy induction (fun

Obstructive Intramural Coronary Amyloidosis: Uncommon or Under-Recognized Cause of Microvascular Angina?

BACKGROUND: Obstructive intramural coronary amyloidosis (OICA) can be the unique manifestation of cardiac amyloidosis (CA). The clinical onset may mimic ischemic heart disease as microvascular angina or myocardial infarction. CASE SUMMARY: We report an 83-year-old man with long-standing angina, recurrent ischemic symptoms, and persistently elevated troponin levels despite normal coronary angiographies, negative bone scintigraphy, and nondiagnostic cardiac magnetic resonance. Given the clinical suspicion for CA, endomyocardial biopsy was performed and showed extensive transthyretin amyloid dep

Advancement of NF-κB Signaling Pathway: A Novel Target in Pancreatic Cancer.

Pancreatic ductal adenocarcinoma (PDAC) is one of the deadliest cancers and is the third highest among cancer related deaths. Despite modest success with therapy such as gemcitabine, pancreatic cancer incidence remains virtually unchanged in the past 25 years. Among the several driver mutations for PDAC, Kras mutation contributes a central role for its development, progression and therapeutic resistance. In addition, inflammation is implicated in the development of most human cancer, including pancreatic cancer. Nuclear factor kappa-light-chain-enhancer of activated B cells (NF-κB) is recogniz
