The protective effects of capsaicin on oxidative damage-induced by 2,3,7,8-tetrachlorodibenzo-p-dioxin in rats.

Drug Chem Toxicol 2021 Jul 26:1-8. Epub 2021 Jul 26.

Department of Pharmacology, Faculty of Medicine, University of Pamukkale, Denizli, Turkey.

The present study aimed to investigate the protective role of capsaicin in a rat model of 2,3,7,8-tetracholorodibenzo-p-dioxin (TCDD)-induced toxicity. Exposure to TCDD which is an environmental toxicant causes severe toxic effects in the animal and human tissues. Therefore, the potential protective effect of capsaicin in TCDD-induced organ damage was investigated in rats by measuring thiobarbituric acid reactive substances (TBARS) level, superoxide dismutase (SOD) activity, and glutathione (GSH) level in the heart, liver, and kidney tissues for oxidant/antioxidant balance.

KSHV-encoded vCyclin can modulate HIF1α levels to promote DNA replication in hypoxia.

Elife 2021 Jul 19;10. Epub 2021 Jul 19.

Department of Otorhinolaryngology-Head and Neck Surgery, Perelman School of Medicine, University of Pennsylvania, Philadelphia, United States.

The cellular adaptive response to hypoxia, mediated by high HIF1α levels includes metabolic reprogramming, restricted DNA replication and cell division. In contrast to healthy cells, the genome of cancer cells, and Kaposi's sarcoma associated herpesvirus (KSHV) infected cells maintains replication in hypoxia. We show that KSHV infection, despite promoting expression of HIF1α in normoxia, can also restrict transcriptional activity, and promoted its degradation in hypoxia. Read More

Doxorubicin and doxorubicin-loaded nanoliposome induce senescence by enhancing oxidative stress, hepatotoxicity, and in vivo genotoxicity in male Wistar rats.

Naunyn Schmiedebergs Arch Pharmacol 2021 Aug 5;394(8):1803-1813. Epub 2021 Jul 5.

Research Center for Pharmaceutical Nanotechnology, Biomedicine Institute, Tabriz University of Medical Sciences, Tabriz, Iran.

The senescence phenomenon is historically considered as a tumor-suppressing mechanism that can permanently arrest the proliferation of damaged cells, and prevent tumor eradication by activating cell cycle regulatory pathways. Doxorubicin (DX) as an antineoplastic agent has been used for the treatment of solid and hematological malignancies for a long time, but its clinical use is limited due to irreversible toxicity on off-target tissues. Thereby, the encapsulation of plain drugs in a vehicle may decrease the side effects while increasing their permeability and availability in target cells. Read More

Static Magnetic Stimulation Induces Changes in the Oxidative Status and Cell Viability Parameters in a Primary Culture Model of Astrocytes.

Cell Biochem Biophys 2021 Jun 27. Epub 2021 Jun 27.

Coordinator of NeuroCell Laboratory, Laboratory of Histology, Department of Morphology, Post-Graduate Program in Biochemistry and Bioprospection, Universidade Federal de Pelotas Avenida Duque de Caxias, 250, 96030-000, Pelotas, Rio Grande do Sul, Brasil.

Astrocytes play an important role in the central nervous system function and may contribute to brain plasticity response during static magnetic fields (SMF) brain therapy. However, most studies evaluate SMF stimulation in brain plasticity while few studies evaluate the consequences of SMF at the cellular level. Thus, we here evaluate the effects of SMF at 305 mT (medium-intensity) in a primary culture of healthy/normal cortical astrocytes obtained from neonatal (1 to 2-day-old) Wistar rats. Read More

Cancer-induced muscle atrophy is determined by intrinsic muscle oxidative capacity.

FASEB J 2021 07;35(7):e21714

School of Physical Education and Sport, University of Sao Paulo, Sao Paulo, Brazil.

We tested the hypothesis that cancer cachexia progression would induce oxidative post-translational modifications (Ox-PTMs) associated with skeletal muscle wasting, with different responses in muscles with the prevalence of glycolytic and oxidative fibers. We used cysteine-specific isotopic coded affinity tags (OxICAT) and gel-free mass spectrometry analysis to investigate the cysteine Ox-PTMs profile in the proteome of both plantaris (glycolytic) and soleus (oxidative) muscles in tumor-bearing and control rats. Histological analysis revealed muscle atrophy in type II fibers in plantaris muscle, with no changes in plantaris type I fibers and no differences in both soleus type I and II fibers in tumor-bearing rats when compared to healthy controls.
