Endothelial TFEB signaling-mediated autophagic disturbance initiates microglial activation and cognitive dysfunction.

Cognitive impairment caused by systemic chemotherapy is a critical question that perplexes the effective implementation of clinical treatment, but related molecular events are poorly understood. Herein, we show that bortezomib exposure leads to microglia activation and cognitive impairment, this occurs along with decreased nuclear translocation of TFEB (transcription factor EB), which is linked to macroautophagy/autophagy disorder, STAT3 (signal transducer and activator of transcription 3) phosphorylation and IL23A (interleukin 23 subunit alpha) expression. Pharmacological enhancement of TFEB

Increased Circulating Soluble Junctional Adhesion Molecules in Systemic Sclerosis: Association with Peripheral Microvascular Impairment.

Systemic sclerosis (SSc, scleroderma) is a severe disease characterized by peripheral microcirculation abnormalities manifesting with Raynaud's phenomenon, nailfold videocapillaroscopic (NVC) changes, and even ischemic digital ulcers (DUs) that are often refractory to treatments. In the wake of previously described associations between the circulating levels of soluble junctional adhesion molecules (sJAMs) and SSc clinical features, here, we measured sJAM-A and sJAM-C levels by enzyme-linked immunosorbent assay in serum samples from a large case series of 110 SSc patients and 85 healthy contro

Anti-tumor effect of inhibition of IL-6 signaling in mucoepidermoid carcinoma.

Mucoepidermoid carcinoma (MEC) is the most frequent malignant salivary gland cancer. Response to chemoradiotherapy is modest, and therefore radical surgery remains the standard-of-care. Emerging evidence suggests that Interleukin (IL)-6 signaling correlates with the survival of cancer stem cells and resistance to therapy. Here, we investigated whether inhibition of IL-6 receptor (IL-6R) signaling with tocilizumab (humanized anti-human IL-6R antibody) sensitizes MEC to chemotherapy using human mucoepidermoid carcinoma cell lines (UM-HMC) and correspondent xenograft models. In vitro, we observed

The role of interleukin 17 in tumour proliferation, angiogenesis, and metastasis.

With 7.6 million deaths globally, cancer according to the World Health Organisation is still one of the leading causes of death worldwide. Interleukin 17 (IL-17) is a cytokine produced by Th17 cells, a T helper cell subset developed from an activated CD4+ T-cell. Whilst the importance of IL-17 in human autoimmune disease, inflammation, and pathogen defence reactions has already been established, its potential role in cancer progression still needs to be updated. Interestingly studies have demonstrated that IL-17 plays an intricate role in the pathophysiology of cancer, from tumorigenesis, prol

Thalidomide Suppresses Angiogenesis Through the Signal Transducer and Activator of Transcription 3/SP4 Signaling Pathway in the Peritoneal Membrane.

Peritoneal angiogenesis is the key pathophysiological factor that limits peritoneal ultrafiltration during peritoneal dialysis (PD) in uremic patients. Thalidomide has been confirmed to inhibit angiogenesis by inhibiting the secretion of vascular endothelial growth factor (VEGF), but the exact mechanism by which thalidomide inhibits vascular proliferation during PD is still unclear. Here, the objective of the present study was to investigate whether the reduction in VEGF production by human peritoneal mesothelial cells (HPMCs) was controlled by thalidomide. Stimulation of HPMCs with IL-6 in co

Metformin-induced vitamin B12 deficiency: An underdiagnosed cause of diabetic neuropathy.

Metformin-induced vitamin B12 deficiency is a prevalent condition among patients with type 2 diabetes mellitus. In recent years, a growing body of evidence has demonstrated the association between vitamin B12 deficiency and the onset, progression, and worsening of diabetic neuropathy (DNP) as well as its improvement with supplementation in cases of deficiency. Major clinical guidelines for diabetes and DNP remain vague in their recommendations for B12 measurement and supplementation, and some guidelines do not address it at all. Given that vitamin B12 therapy is an economical, safe, and widely

COVID-19 signalome: Pathways for SARS-CoV-2 infection and impact on COVID-19 associated comorbidity.

The COVID-19 pandemic has been the focus of research the past two years. The major breakthrough was made by discovering pathways related to SARS-CoV-2 infection through cellular interaction by angiotensin-converting enzyme (ACE2) and cytokine storm. The presence of ACE2 in lungs, intestines, cardiovascular tissues, brain, kidneys, liver, and eyes shows that SARS-CoV-2 may have targeted these organs to further activate intracellular signalling pathways that lead to cytokine release syndrome. It has also been reported that SARS-CoV-2 can hijack coatomer protein-I (COPI) for S protein retrograde

An integrative review of nonobvious puzzles of cellular and molecular cardiooncology.

Oncologic patients are subjected to four major treatment types: surgery, radiotherapy, chemotherapy, and immunotherapy. All nonsurgical forms of cancer management are known to potentially violate the structural and functional integrity of the cardiovascular system. The prevalence and severity of cardiotoxicity and vascular abnormalities led to the emergence of a clinical subdiscipline, called cardiooncology. This relatively new, but rapidly expanding area of knowledge, primarily focuses on clinical observations linking the adverse effects of cancer therapy with deteriorated quality of life of

Геномическая аттестация в Biobank Cohort предлагает роль C8B и MFG-E8 в патогенезе Тригеминальной Невралгии.

Тригеминальная нейронгия (TN) — серьезная болевая болезнь, вызванная неопределенной патофизиологией и неясным генетическим фоном. Хотя недавние исследования свидетельствуют о том, что генетические факторы играют более важную роль в патогенезе ТН, на сегодняшний день было предложено несколько потенциальных генов. Цель настоящего исследования состояла в том, чтобы выявить независимые генетические варианты генов белкового кодирования, связанных с ТН. Мы сосредоточились на генах, ранее связанных с TN, на основе результатов four Протеомные исследования, проведенные нашей исследовательской группой.

CXCL13 Повреждает позвоночник крови, поощряя RNF6/Sqstm1-Ubictiination.

Повреждение позвоночника крови (BSCB) приводит к нарушению иммунной микроокружающей среды в центральной нервной системе во время развития множественного склероза (MS) и экспериментального аллергического энцефаломиэлита (EAE). Тем не менее основные механизмы, связанные с повреждением барьера, по-прежнему недостаточно изучены. Здесь, анализируя белковые профили в периферической сыворотке крови, хемокин (C-X-C motif) Ligand 13 (CXCL13) был определен как возрастающий по мере развития MS и EAE. Отсутствие CXCL13 привело к снижению симптомов EAE, о чем свидетельствует сокращение числа клинических оц

Anticancer Role of PPARgamma Agonists in Hematological Malignancies Found in the Vasculature, Marrow, and Eyes.

The use of targeted cancer therapies in combination with conventional chemotherapeutic agents and/or radiation treatment has increased overall survival of cancer patients. However, longer survival is accompanied by increased incidence of comorbidities due, in part, to drug side effects and toxicities. It is well accepted that inflammation and tumorigenesis are linked. Because peroxisome proliferator-activated receptor (PPAR)-gamma agonists are potent mediators of anti-inflammatory responses, it was a logical extension to examine the role of PPARgamma agonists in the treatment and prevention of
