- |||||||||| Review, Journal, IO Biomarker: Autophagy as a Potential Therapy for Malignant Glioma. (Pubmed Central) - Jul 28, 2020
Modulating the autophagic pathway as a death mechanism for cancer cells has prompted the use of both inhibitors and autophagy inducers. The autophagic process, either as a cancer suppressing or inducing mechanism in high-grade gliomas is discussed in this review, along with therapeutic approaches to inhibit or induce autophagy in pre-clinical and clinical studies, aiming to increase the efficiency of conventional treatments to remove glioma neoplastic cells.

Preclinical, Review, Journal: Autophagy modulation in animal models of corneal diseases: a systematic review. (Pubmed Central) - Jul 28, 2020 Protective effects of autophagy activators were demonstrated, including rapamycin for DED and keratitis, lithium for FECD, LYN-1604 for DED, cysteamine and miR-34c antagomir for damaged corneal epithelium. Three autophagy suppressors were also found to have therapeutic effects, such as aminoimidazole-4-carboxamide-riboside (AICAR) for corneal allogeneic transplantation, celecoxib and chloroquine for DED.

However, there were no significant changes in the expression levels of TNF-α and IL-10 in the db/db group. Therefore, Baf A1 may accelerate diabetic chronic refractory wound healing by promoting cell proliferation, collagen production, and regulating the inflammatory balance.

Biomarker, Preclinical, Journal: Chondroprotection of PPARα activation by WY14643 via autophagy involving Akt and ERK in LPS-treated mouse chondrocytes and osteoarthritis model. (Pubmed Central) - Jul 25, 2020 In this study, we investigated the effect of PPARα activation by its agonist, WY14643, on the protein expression level of Aggrecan and ADAMTS5, and the protein expression level of autophagy biomarkers, including LC3B and P62, using Western blotting analysis in isolated mouse chondrocytes pre-treated with lipopolysaccharides (LPS, mimicking OA chondrocytes) with or without the autophagy inhibitor chloroquine diphosphate salt...The results indicated that PPARα activation by WY14643 promoted proteoglycan synthesis by autophagy enhancement in OA chondrocytes in vivo and in vitro concomitant with the elevation of Akt and ERK phosphorylation. Therefore, autophagy could contribute to the chondroprotection of PPARα activation by WY14643, with the implication that PPARα activation by WY14643 may be a potential approach for OA therapy.

Journal: Endurance Exercise Attenuates Doxorubicin-induced Cardiotoxicity. (Pubmed Central) - Jul 21, 2020 Our data provide novel findings that EXE-induced auto/mitophagy promotion and NOX2 downregulation are linked to cardioprotection against DOX-induced cardiotoxicity. Importantly, our study shows that EXE postconditioning intervention is effective and efficacious to prevent DOX-induced cardiac injuries.

In addition, BNIP3-mediated mitophagy played a protective role against VSMC calcification in the presence of lactate. This study suggests that lactate accelerates osteoblastic phenotype transition of VSMC and calcium deposition partly through the BNIP3-mediated mitophagy deficiency induced oxidative stress and apoptosis.

Blocking endolysosomal pathways using autophagy inhibitors prevented the degradation of AANTs through lysosomes. Our results add new insights into the pathways and mechanisms of intracellular trafficking of AANTs, and suggest that intracellular trafficking and lysosomal degradation are highly interdependent and important for efficient drug delivery, and should be evaluated together for drug carrier development.

[VIRTUAL] Homozygous mutations of ARFGAP1 gene in severe sarcoidosis (Pre-congress content) - Jul 15, 2020 - Abstract #ERS2020ERS_3737; RAC1 is one of the main targets of azathioprine (AZA), an immunosuppressive drug used in corticosteroid (CS) refractory sarcoidosis...We would hypothesize that ARFGAP1 mutated isoforms have lost their inhibitory function with a consequence of hyperactivation of RAC1 thus leading to autophagy inhibition. Autophagy disruption seems to be an interesting element of pathophysiology in sarcoidosis, previously evoked in WES studies and through the efficacy of autophagy modulating drug during sarcoidosis.

[VIRTUAL] Cigarette-decreased NAD/SIRT1 aggravates pulmonary fibrosis by promoting senescence of alveolar type 2 cells through autophagy inhibition and mitochondrial oxidative stress induction (Pre-congress content) - Jul 15, 2020 - Abstract #ERS2020ERS_223; After senescent markers were increased, they were treated with bleomycin (BLM) and smoke for 4 weeks...Then, effects of autophagy inducer rapamycin, SIRT1 activator SRT1720, NAD+ precursor NMN, PARP1 inhibitor olaparib and mitochondrial ROS (mtROS) scavenger, mitoquinone (MQ) were examined...Conclusion Cigarette-decreased NAD+/SIRT1 resulting from PARP1 activation induce AT2 senescence by inhibiting autophagy, which further activate PARP1 via mtROS-induced DNA damage by impairing mitophagy. Therefore, there is a positive loop in cigarette-induced senescence, which may play a key role in lung fibrosis.

Intact autophagy is necessary for endothelial cells to invade the extracellular matrix as well as for the expression of active endothelial MMP14.

Sirolimus is an agent for the treatment of LAM, indicated for FEV1 of less than 70% of predicted, patients on traditional therapies are recommended to be transitioned to newer FDA approved drugs for LAM.

[VIRTUAL] The Influence of Autophagy Inhibition on Sepsis-Induced Skeletal Muscle Wasting, Metabolic Derangements and Mortality (ATS 2020 Virtual) - Jul 6, 2020 - Abstract #ATSI2020ATS-I_3747; We conclude that autophagy plays a protective role by preserving muscle mitochondrial quality and function and that autophagy inhibition in skeletal muscles worsens sepsis-induced loss of body weight and muscle atrophy possibly due to exaggerated responses to catabolic stimuli triggered by sepsis. Our results also indicate that autophagy in septic skeletal muscles play a protective role against sepsis-induced metabolic derangements and mortality.
