Association of gene variants with juvenile amyotrophic lateral sclerosis

Frontiers of Medicine doi: 10.1007/s11684-023-1005-y

Abstract: Amyotrophic lateral sclerosis (ALS) is a fatal neurodegenerative disease characterized by progressive degeneration of motor neurons, and it demonstrates high clinical heterogeneity and complex genetic architecture. A variation within TRMT2B (c.1356G>T; p.K452N) was identified to be associated with ALS in a family comprising two patients with juvenile ALS (JALS). Two missense variations and one splicing variation were identified in 10 patients with ALS in a cohort with 910 patients with ALS, and three more variants were identified in a public ALS database including 3317 patients with ALS. A decreased number of mitochondria, swollen mitochondria, lower expression of ND1, decreased mitochondrial complex I activities, lower mitochondrial aerobic respiration, and a high level of ROS were observed functionally in patient-originated lymphoblastoid cell lines and TRMT2B interfering HEK293 cells. Further, TRMT2B variations overexpression cells also displayed decreased ND1. In conclusion, a novel JALS-associated gene called TRMT2B was identified, thus broadening the clinical and genetic spectrum of ALS.

Abstract:

Antibiotic-resistant bacteria and antibiotic resistance genes are in water bodies.

UV/chlorination method is better to remove ARGs than UV or chlorination alone.

Research on UV/hydrogen peroxide to eliminate ARGs is forthcoming.

UV-based photocatalytic processes are effective to degrade ARGs.

Mechanism of vascular endothelial growth factor on the prevention of restenosis after angioplasty

Qigong LIU, Honglian ZHOU, Yan ZENG, Shan YE, Jiani LIU, Zaiying LU

Frontiers of Medicine 2009, Volume 3, Issue 2,   Pages 177-180 doi: 10.1007/s11684-009-0021-x

Abstract: To evaluate the mechanism of vascular endothelial growth factor (VEGF) on the prevention of restenosis after angioplasty, the recombinant adenovirus vector containing hVEGF cDNA was constructed and transfected into vascular smooth muscle cells (VSMC) . The conditioned medium containing VEGF was collected 72 h after the infection. Then, the VSMC and human umbilical vein endothelial cells (HUVEC) were divided into control group, H O -treated group and H O +VEGF-treated group to observe the proliferation and apoptosis by water soluble tetrazolium (WST-1) method, nick end labeling (TUNEL) and flow cytometry (FCM). Compared with the control and H O +VEGF-treated groups, the absorbance ( ) value of HUVEC was decreased, and apoptosis of HUVEC was significantly increased in H O -treated group. The changes of value and apoptosis of VSMC were contrary to those of HUVEC. H O could stimulate the proliferation of VSMC and induce the apoptosis of HUVEC, inhibit the proliferation of HUVEC and the apoptosis of VSMC and induce restenosis. VEGF could inhibit the effect of H O on HUVEC and VSMC and prevent restenosis. These results offered further theoretical evidence for VEGF on the prevention of restenosis after angioplasty.
