One of the key characteristics of aging is a progressive loss of physiological integrity, which weakens bodily functions and increases the risk of death. A robust biomarker is important for the assessment of biological age, the rate of aging, and a person's health status. DNA methylation clocks, novel biomarkers of aging, are composed of a group of cytosine-phosphate-guanine dinucleotides, the DNA

Animal models of regenerative medicine for biological treatment approaches of degenerative disc diseases Exp. Biol. Med. (IF 3.139) Pub Date : 2020-11-11 Demissew Shenegelegn Mern; Tanja Walsen; Anja Beierfuß; Claudius Thomé
Degenerative disc disease (DDD) is a painful, chronic and progressive disease, which is characterized by inflammation, structural and biological deterioration of the intervertebral disc (IVD) tissues. DDD is specified as cell-, age-, and genetic-dependent degenerative process that can be accelerated by environmental factors. It is one of the major causes of chronic back pain and disability affecting

Influence of Pseudomonas autoinducer N-3-oxododecanoyl homoserine lactone on human corneal epithelial cells Exp. Biol. Med. (IF 3.139) Pub Date : 2020-11-11 Renjian Hu; Kelan Yuan; Jie Zhou; Yue Zhang; Jiao Zheng; Yingying Zhao; Xiaodan Huang; Xiuming Jin
The quorum-sensing (QS) signaling-dependent extracellular virulence factors of Pseudomonas aeruginosa can cause infections such as P. aeruginosa keratitis. P. aeruginosa communicates by secreting and sensing small chemical molecules called autoinducers in QS system. The key QS signal molecule, N-3-oxododecanoyl-homoserine lactone (3OC12HSL), can affect the behavior of host cells and initiate immune

Mitophagy promotes the stemness of bone marrow-derived mesenchymal stem cells Exp. Biol. Med. (IF 3.139) Pub Date : 2020-11-10 Xiaorong Feng; Wen Yin; Jialing Wang; Li Feng; Y James Kang
Previous studies demonstrated that mitochondrial fission arguments the stemness of bone marrow-derived mesenchymal stem cells (BMSCs). Because mitophagy is critical in removing damaged or surplus mitochondrial fragments and maintaining mitochondrial integrity, the present study was undertaken to test the hypothesis that mitophagy is involved in mitochondrial fission-enhanced stemness of BMSCs. Primary

Hypoxia–CXCL6 axis affects arteriolar niche remodeling in acute myeloid leukemia Exp. Biol. Med. (IF 3.139) Pub Date : 2020-11-09 Lijun Li; Jiancheng Man; Li Zhao
Acute myeloid leukemia (AML) is a malignant clonal disease derived from hematopoietic stem/progenitor cell. Leukemia blasts cause extensive hypoxia of bone marrow (BM), which lead to disorder and remodeling of BM niche, thereby becoming “leukemic niche” to support the development and drug-resistance of AML as well as the maintenance of normal hematopoietic stem cells. In this study, the biological

Recent developments in autophagy-targeted therapies in cancer Exp. Biol. Med. (IF 3.139) Pub Date : 2020-11-09 Manasi P Jogalekar; Anurag Veerabathini; Prakash Gangadaran
Autophagy plays a crucial role in cellular development and differentiation as well as in the maintenance of homeostasis in healthy cells. Autophagy is well documented in neurodegenerative disorders, aging, and infectious diseases. However, recognizing its significance in cancer has always been challenging due to its tumor-promoting and suppressive attributes. Various modulators targeting key components

Etiological classification and treatment strategies for secondary bile duct dilatation Exp. Biol. Med. (IF 3.139) Pub Date : 2020-11-09 Yunfu Lv; Ning Liu; Hongfei Wu; Zhuori Li
Secondary intra- and extrahepatic bile duct dilatation is a very common condition that can be caused by several diseases. However, it has been rarely discussed in the specialized literature. Moreover, no distinct etiology can be determined in some cases, which hampers the diagnosis and treatment. Here, we discuss the etiological classification and treatment strategies of secondary intra- and extrahepatic

Detection of severe acute respiratory syndrome coronavirus 2 and influenza viruses based on CRISPR-Cas12a Exp. Biol. Med. (IF 3.139) Pub Date : 2020-11-05 Oraphan Mayuramart; Pattaraporn Nimsamer; Somruthai Rattanaburi; Naphat Chantaravisoot; Kritsada Khongnomnan; Jira Chansaenroj; Jiratchaya Puenpa; Nungruthai Suntronwong; Preeyaporn Vichaiwattana; Yong Poovorawan; Sunchai Payungporn
Due to the common symptoms of COVID-19, patients are similar to influenza-like illness. Therefore, the detection method would be crucial to discriminate between SARS-CoV-2 and influenza virus-infected patients. In this study, CRISPR-Cas12a-based detection was applied for detection of severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2), influenza A virus, and influenza B virus which would be

Prenatal indole-3-carbinol administration activates aryl hydrocarbon receptor-responsive genes and attenuates lung injury in a bronchopulmonary dysplasia model Exp. Biol. Med. (IF 3.139) Pub Date : 2020-11-04 Gabriela Guzmán-Navarro; Mario Bermúdez de León; Irene Martín-Estal; Raquel Cuevas-Díaz Durán; Laura Villarreal-Alvarado; Anakaren Vaquera-Vázquez; Tania Cuevas-Cerda; Karina Garza-García; Luis Eduardo Cuervo-Pérez; Álvaro Barbosa-Quintana; José Eduardo Pérez-Saucedo; Víctor J Lara-Díaz; Fabiola Castorena-Torres
Hyperoxia−hypoxia exposure is a proposed cause of alveolar developmental arrest in bronchopulmonary dysplasia in preterm infants, where mitochondrial reactive oxygen species and oxidative stress vulnerability are increased. The aryl hydrocarbon receptor (AhR) is one of the main activators of the antioxidant enzyme system that protects tissues and systems from damage. The present study aimed to determine

Transcriptomic profiles in Parkinson’s disease Exp. Biol. Med. (IF 3.139) Pub Date : 2020-11-04 Lille Kurvits; Freddy Lättekivi; Ene Reimann; Liis Kadastik-Eerme; Kristjan M Kasterpalu; Sulev Kõks; Pille Taba; Anu Planken
Transcriptomics in Parkinson’s disease offers insights into the pathogenesis of Parkinson’s disease but obtaining brain tissue has limitations. In order to bypass this issue, we profile and compare differentially expressed genes and enriched pathways (KEGG) in two peripheral tissues (blood and skin) of 12 Parkinson’s disease patients and 12 healthy controls using RNA-sequencing technique and validation
