Circulating miR-424 positive EVs from patients with aggressive primary and metastatic tumors induced stem-like features when supplemented to prostate epithelial cells. This study establishes that EVs-mediated transfer of miR-424 across heterogeneous cell populations is an important mechanism of tumor self-sustenance, disease recurrence and progression. These findings might indicate novel approaches for the management and therapy of prostate cancer.WD40 domain-containing proteins constitute one of the most abundant protein families in all higher plants and play vital roles in the regulation of plant growth and developmental processes. To date, WD40 protein members have been identified in several plant species, but no report is available on the WD40 protein family in mango (Mangifera indica L.). In this study, a total of 315 WD40 protein members were identified in mango and further divided into 11 subgroups according to the phylogenetic tree. Here, we reported mango TRANSPARENT TESTA GLABRA 1 (MiTTG1) protein as a novel factor that functions in the regulation of Arabidopsis root growth and development. Bimolecular fluorescence complementation (BiFC) assay in tobacco leaves revealed that MiTTG1 protein physically interacts with MiMYB0, MiTT8 and MibHLH1, implying the formation of a new ternary regulatory complex (MYB-bHLH-WD40) in mango. Furthermore, the MiTTG1 transgenic lines were more adapted to abiotic stresses (mannitol, salt and drought stress) in terms of promoted root hairs and root lengths. Together, our findings indicated that MiTTG1 functions as a novel factor to modulate protein-protein interactions and enhance the plants abilities to adjust different abiotic stress responses.The ABCD1 protein, one of the four ATP-binding cassette (ABC) proteins in subfamily D, is located on the peroxisomal membrane and is involved in the transport of very long chain fatty acid (VLCFA)-CoA into peroxisomes. Its mutation causes X-linked adrenoleukodystophy (X-ALD) an inborn error of peroxisomal β-oxidation of VLCFA. Whether ABCD1 transports VLCFA-CoA as a CoA ester or free fatty acid is controversial. Recently, Comatose (CTS), a plant homologue of human ABCD1, has been shown to possess acyl-CoA thioesterase (ACOT) activity, and it is suggested that this activity is required for transport of acyl-CoA into peroxisomes. However, the precise transport mechanism is unknown. Here, we expressed human His-tagged ABCD1 in methylotrophic yeast, and characterized its ACOT activity and transport mechanism. The expressed ABCD1 possessed both ATPase and ACOT activities. The ACOT activity of ABCD1 was inhibited by p-chloromercuribenzoic acid (pCMB), a cysteine-reactive compound. Furthermore, we performed a transport assay with ABCD1-containing liposomes using 7-nitro-2-1,3-benzoxadiazol-4-yl (NBD)-labeled acyl-CoA as the substrate. The results showed that the fatty acid produced from VLCFA-CoA by ABCD1 is transported into liposomes and that ACOT activity is essential during this transport process. We propose a detailed mechanism of VLCFA-CoA transport by ABCD1.Wolfram syndrome (WS) is a monogenic progressive neurodegenerative disease and is characterized by various neurological symptoms, such as optic nerve atrophy, loss of vision, cognitive decline, memory impairment, and learning difficulties. GLP1 receptor agonist liraglutide and BDNF mimetic 7,8-dihydroxyflavone (7,8-DHF) have had protective effect to visual pathway and to learning and memory in different rat models of neurodegenerative disorders. learn more Although synergistic co-treatment effect has not been reported before and therefore the aim of the current study was to investigate liraglutide, 7,8-DHF and most importantly for the first time their co-treatment effect on degenerative processes in WS rat model. We took 9 months old WS rats and their wild-type (WT) control animals and treated them daily with liraglutide, 7,8-DHF or with the combination of liraglutide and 7,8-DHF up to the age of 12.5 months (n = 47, 5-8 per group). We found that liraglutide, 7,8-DHF and their co-treatment all prevented lateral ventricle enlargement, improved learning in Morris Water maze, reduced neuronal inflammation, delayed the progression of optic nerve atrophy, had remyelinating effect on optic nerve and thereby improved visual acuity in WS rats compared to WT controls. Thus, the use of the liraglutide, 7,8-DHF and their co-treatment could potentially be used as a therapeutic intervention to induce neuroprotection or even neuronal regeneration.Heterozygous pathogenic variants in SLC12A2 are reported in patients with nonsyndromic hearing loss. Recently, homozygous loss-of-function variants have been reported in two patients with syndromic intellectual disability, with or without hearing loss. However, the clinical and molecular spectrum of SLC12A2 disease has yet to be characterized and confirmed. Using whole-exome sequencing, we detected a homozygous splicing variant in four patients from two independent families with severe developmental delay, microcephaly, respiratory abnormalities, and subtle dysmorphic features, with or without congenital hearing loss. We also reviewed the reported cases with pathogenic variants associated with autosomal dominant and recessive forms of the SLC12A2 disease. About 50% of the cases have syndromic and nonsyndromic congenital hearing loss. All patients harboring the recessive forms of the disease presented with severe global developmental delay. Interestingly, all reported variants are located in the c-terminal domain, suggesting a critical role of this domain for the proper function of the encoded co-transporter protein. In conclusion, our study provides an additional confirmation of the autosomal recessive SLC12A2 disease.This study aimed to determine whether geniohyoid and/or masseter muscle mass can predict the severity of dysphagia after salvage surgery for head and neck cancer. We conducted a retrospective cohort study of 45 male patients with head and neck cancer (median age, 68 years) who underwent salvage surgery. The preoperative geniohyoid and masseter muscle masses were evaluated using computed tomography and the severity of dysphagia was evaluated by Penetration Aspiration Scale (PAS), Functional Oral Intake Scale (FOIS) and Oropharyngeal swallow efficiency (OPSE). The median PAS, FOIS and OPSE scores after surgery were 7 (interquartile range [IQR] 1-8), 6 (IQR 2-7) and 95.8 (IQR 67.1-116.2), respectively. The mean geniohyoid muscle masses were 3.13 ± 0.78 cm2 and the mean masseter muscle masses were 4.37 ± 0.99 cm2, respectively. The multivariate analysis showed that the geniohyoid muscle mass was significantly associated with the PAS, FOIS and OPSE scores. Conversely, the masseter muscle mass was not significantly associated with the PAS score but was significantly associated with the FOIS and OPSE scores.
