Paternal exercise induces antioxidant defenses by α-Klotho/Keap1 pathways in the skeletal muscle of offspring exposed to a high fat-diet without changing telomere length.

Although previous studies demonstrated that the ancestral lifestyle can enhance the metabolic health of offspring exposed to an obesogenic diet, the specific connections between these positive effects in redox state and telomere length are unknown. We investigated the impact of paternal resistance training (RT) on stress-responsive signaling and the pathways involved in telomere homeostasis in skeletal muscle. This investigation encompassed both the fathers and first-generation litter exposed to a long-term standard diet (24 weeks) and high fat diet (HFD).

Expanding the Toolbox for Functional Genomics in : The Use of Split-Marker and Biolistic Transformation for Inactivation of Tryptophan Synthase () Gene.

Chromoblastomycosis (CBM) is a disease caused by several dematiaceous fungi from different genera, and is the most common which has been clinically isolated. Genetic transformation methods have recently been described; however, molecular tools for the functional study of genes have been scarcely reported for those fungi. In this work, we demonstrated that gene deletion and generation of the null mutant by homologous recombination are achievable for by the use of two approaches: use of double-joint PCR for cassette construction, followed by delivery of the split-marker by biolistic transformation.

Induced resistance to ifosfamide in osteosarcoma cells suggests a more aggressive tumor profile.

Aims: Osteosarcoma (OS) is the most common primary malignant bone sarcoma among children and adolescents. Treatment is based on neo-adjuvant and adjuvant chemotherapy, using the standard drugs cisplatin, methotrexate, doxorubicin, and ifosfamide (IFO). Due to the high capacity of tumor resistance, the current work aimed to analyze genes related to cycle control and cell differentiation in OS cells sensitive to and with induced resistance to IFO.

In-Vitro Growth Kinetics of Mesenchymal Stem Cells in Cytotoxicity Tests Using Low-Diluted Viscum Album.

Introduction:  The use of mesenchymal stem cells (MSC) in cytotoxicity tests is an alternative model for predicting initial doses. Homeopathic medicines may stimulate the immune system to combat a pathology effectively and have been used for over two centuries. (VA) extracts are widely used in the treatment of cancer, due to their immunomodulatory, cytotoxic and pro-apoptotic properties.

Clock Genes, Inflammation and the Immune System-Implications for Diabetes, Obesity and Neurodegenerative Diseases.

Inflammation is a common feature of several diseases, including obesity, diabetes and neurodegenerative disorders. Circadian clock genes are expressed and oscillate in many cell types such as macrophages, neurons and pancreatic β cells. During inflammation, these endogenous clocks control the temporal gating of cytokine production, the antioxidant response, chemokine attraction and insulin secretion, among other processes.

Training Performed Above Lactate Threshold Decreases p53 and Shelterin Expression in Mice.

Telomere shortening is associated to sarcopenia leading to functional impairment during aging. There are mechanisms associated with telomere attrition, as well to its protection and repair. Physical training is a factor that attenuates telomere shortening, but little is known about the effects of different exercise intensities on telomere biology.

Resistance training regulates gene expression of molecules associated with intramyocellular lipids, glucose signaling and fiber size in old rats.

Sarcopenia is a complex multifactorial process, some of which involves fat infiltration. Intramyocellular lipid (IMCL) accumulation is postulated to play a role on sarcopenia during aging, which is believed to be due alterations in glucose homeostasis in the skeletal muscle. Sarcopenia, along with intramuscular lipids, is associated with physical inactivity.

Role of exercise intensity on GLUT4 content, aerobic fitness and fasting plasma glucose in type 2 diabetic mice.

Type 2 diabetes mellitus (T2D) results in several metabolic and cardiovascular dysfunctions, clinically characterized by hyperglycaemia due to lower glucose uptake and oxidation. Physical exercise is an effective intervention for glycaemic control. However, the effects of exercising at different intensities have not yet been addressed.

Use of microRNAs in directing therapy and evaluating treatment response in colorectal cancer.

Colorectal cancer is the third most common cancer worldwide. Survival and prognosis depend on tumor stage upon diagnosis, and in more than 50% of cases, the tumor has already invaded adjacent tissues or metastasis has occurred. Aiming to improve diagnosis, clinical prognosis and treatment of patients with colorectal cancer, several studies have investigated microRNAs as molecular markers of the disease due to their potential regulatory functions on tumor suppressor genes and oncogenes.

SMYD2 is highly expressed in pediatric acute lymphoblastic leukemia and constitutes a bad prognostic factor.

Acute lymphoblastic leukemia (ALL) is the most common childhood malignancy. Although several clinical characteristics can be associated with worse prognosis, more robust biological markers still remains uncovered. SMYD2, a member of SMYD protein family, regulates the activity of several proteins through methylation.

Altered expression of MLL methyltransferase family genes in breast cancer.

The histone lysine methyltransferases contain a SET domain, which catalyzes the addition of methyl groups to specific lysine residues. The MLL family of genes encodes histone-modifying enzymes with histone 3-lysine 4 methyltransferase activity that can regulate gene transcription. The MLL family exists in multi-protein complexes and has been implicated in a variety of processes including normal development and cell growth.
