The protective effect of zinc on morphine-induced testicular toxicity via p53 and Akt pathways: An in vitro and in vivo approach.

J Trace Elem Med Biol 2021 May 8;67:126776. Epub 2021 May 8.

Department of Physiology, Faculty of Medicine, Urmia University of Medical Sciences, Urmia, Iran. Electronic address:

Background: Chronic use of morphine is associated with reproductive complications, such as hypogonadism and infertility. While the side effects of morphine have been extensively studied in the testis, much less is known regarding the effects of morphine on Sertoli cells and the effects of zinc on morphine-induced testicular injury as well as their underlying mechanisms. Therefore, the purpose of this study was to investigate the effect of morphine (alone and co-administered with zinc) on cell viability and apoptosis of the testicular (Sertoli) cells as well as the tumor suppressor p53 and phosphorylated-protein kinase B (p-Akt) protein levels in both in vitro and in vivo models.

Apoptosis is not conserved in plants as revealed by critical examination of a model for plant apoptosis-like cell death.

BMC Biol 2021 May 12;19(1):100. Epub 2021 May 12.

Department of Molecular Sciences, Uppsala BioCenter, Swedish University of Agricultural Sciences and Linnean Center for Plant Biology, P.O. Box 7015, SE-750 07, Uppsala, Sweden.

Background: Animals and plants diverged over one billion years ago and evolved unique mechanisms for many cellular processes, including cell death. One of the most well-studied cell death programmes in animals, apoptosis, involves gradual cell dismantling and engulfment of cellular fragments, apoptotic bodies, through phagocytosis. However, rigid cell walls prevent plant cell fragmentation and thus apoptosis is not applicable for executing cell death in plants. Read More

Detection of Endogenous RASSF1A Interacting Proteins.

Methods Mol Biol 2021 ;2262:303-310

James Graham Brown Cancer Center, University of Louisville, Louisville, KY, USA.

RASSF1A is a Ras effector that promotes the anti-proliferative properties of Ras. It acts as a scaffold protein that regulates several pro-apoptotic signaling pathways, thereby linking Ras to their regulation. However, accumulating evidence suggests that RASSF1A functions as a regulator of other additional biological processes, such as DNA repair and transcription, thereby implicating Ras in the modulation of these biological processes.

College of Life Sciences, Key Laboratory of Animal Reproduction and Germplasm Enhancement in Universities of Shandong, Qingdao Agricultural University, Qingdao, 266109, China. Electronic address:

Natural and synthetic environmental estrogens (EEs), interfering with the physiological functions of the body's estrogens, are widespread and are rising much concern for their possible deleterious effects on human and animal health, in particular on reproduction. In fact, increasing evidence indicate that EEs can be responsible for a variety of disfunctions of the reproductive system especially in females such as premature ovarian insufficiency (POI). Because of their great structural diversity, the modes of action of EEs are controversial. Read More

Synergistic effects of BKM120 and panobinostat on pre-B acute lymphoblastic cells: an emerging perspective for the simultaneous inhibition of PI3K and HDACs.

J Recept Signal Transduct Res 2020 Dec 1:1-9. Epub 2020 Dec 1.

Department of Hematology and Blood Banking, School of Allied Medical Sciences, Shahid Beheshti University of Medical Sciences, Tehran, Iran.

The reputation of conventional treatment in acute lymphoblastic leukemia (ALL) has recently been questioned due to the considerable increment in the number of relapsed patients. The remarkable role of histone deacetylase (HDAC) enzymes in induction of chemo-resistance has provided an opportunity for HDAC inhibitors to be used as a treatment strategy in ALL; however, the compensatory activation of oncogenic pathways may negatively affect their promising effects. In the present study, we found an attenuating effect for PI3K axis on the anti-leukemic effects of panobinostat in pre-B ALL-derived Nalm-6 cells, as the harnessing of this pathway using BKM120 or CAL-101 resulted in a significant reduction in the number of viable cells as well as the metabolic activity.

Drug-induced liver injury: Oltipraz and C2-ceramide intervene HNF-1α/GSTA1 expression via JNK signaling pathway.

J Appl Toxicol 2021 May 6. Epub 2021 May 6.

Department of Basic Veterinary Science, College of Veterinary Medicine, Northeast Agricultural University, Harbin, China.

Drug-induced liver injury (DILI) is a serious and frequently occurring issue in drug development. The c-Jun N-terminal kinase (JNK) signaling pathway plays an important role in many diseases; hepatocyte nuclear factor-1α (HNF-1α) and glutathione S-transferase A1 (GSTA1) are important in regulating liver-specific genes expressions and affecting drug metabolism. Oltipraz is used to treat liver cirrhosis by improving liver function, and C2-ceramide is a pro-apoptotic lipid that regulates multiple signaling pathways. Read More

Epac-1/Rap-1 signaling pathway orchestrates the reno-therapeutic effect of ticagrelor against renal ischemia/reperfusion model.

Biomed Pharmacother 2021 May 3;139:111488. Epub 2021 May 3.

Department of Pharmacology and Toxicology, Faculty of Pharmacy, Ahram Canadian University, 6th of October City, Giza, Egypt.

Despite the renal expression of PY, the purinergic receptor for adenosine diphosphate, few data are available to discuss the renotherapeutic potential of ticagrelor, one of its reversible blockers. Indeed, the tonic inhibitory effect of this receptor has been linked to the activation of exchange protein activated by cyclic adenosine monophosphate-1 (Epac-1) protein through the cyclic adenosine monophosphate cascade. Epac-1 is considered a crossroad protein, where its activation has been documented to manage renal injury models. Read More

Overexpression of microRNA‑486 affects the proliferation and chemosensitivity of mesothelioma cell lines by targeting .

Int J Mol Med 2021 Jun 6;47(6). Epub 2021 May 6.

Department of Medicine and Surgery, University of Parma, I-43126 Parma, Italy.

Dysregulated levels of microRNAs (miRNAs or miRs), involved in oncogenic pathways, have been proposed to contribute to the aggressiveness of malignant pleural mesothelioma (MPM). Previous studies have highlighted the downregulation of miRNA miR‑486‑5p in patients with mesothelioma and the introduction of miRNA mimics to restore their reduced or absent functionality in cancer cells is considered an important therapeutic strategy. The aim of the present study was to evaluate the mechanisms through which miRNAs may influence the functions, proliferation and sensitivity to cisplatin of MPM cells. Read More
