High impact information on MT-ND2

  • We present new mitochondrial DNA sequences, approximately 2,100 base pairs from the genes encoding ND1, ND2, COI, and the intervening tRNA genes for 34 species representing all 10 salamander families, to examine these relationships [9].
  • The lysosomal band also contained a majority of the NADH2-cytochrome c reductase, a marker enzyme for endoplasmic reticulum, found in the gradient [10].
  • The geographic distribution of ND2 haplotypes is consistent with roles for multiple founder events and introgressive hybridization in the evolution of cave-related phenotypes [11].
  • We have assessed the expression of the mitochondrial ND2 and ND5 (subunits of the nicotinamide adenine dinucleotide dehydrogenase complex) genes and the nuclear UCP2 (uncoupling protein 2) gene in 22 oxyphilic thyroid tumors and matched controls [12].
  • OBJECTIVE: To evaluate the significance of a longevity-associated mitochondrial genotype (Mt5178A) derived from a C --> A transversion at nucleotide position 5178 of mitochondrial DNA, which causes a Leu-to-Met substitution within the NADH dehydrogenase subunit 2 gene, in type 2 diabetic subjects [13].
 

Chemical compound and disease context of MT-ND2

 

Biological context of MT-ND2

 

Anatomical context of MT-ND2

  • As complex I genes are the most vulnerable part of mtDNA we analyzed the mitochondrial MTND1 and MTND2 genes of 10 substantia nigra and 85 platelet samples from PD patients [21].
  • The somata of ND2 cells were medium-sized (mean, 8.2 microns) and located in the INL and in the GCL; their dendrites were usually beaded and often spread in either the middle or outer strata of the IPL [22].
  • NADPH-diaphorase reactivity was observed in three different classes of amacrine cells (ND1, ND2, ND3 cells) and in the cone photoreceptors [22].
  • Since this finding suggested that ND2 gene expression was related to myeloid differentiation, we here investigated the effects of rotenone, a specific NADH dehydrogenase inhibitor, on HL-60 cell growth, differentiation and death [23].
  • To determine whether deletions in the minor region also contribute to the ageing process, we analyzed a 3,610-basepair deletion (nucleotide position 1,837-5,447, from the 16S rRNA gene to the ND2 gene) in the skeletal muscle from individuals of various ages [24].
 

Associations of MT-ND2 with chemical compounds

  • In one individual, we detected a T-to-C transition at position 1243 in the 12SrRNA, a change from threonine to alanine at position 67 of the ND1 protein, and from valine to isoleucine at position 197 of the ND2 protein [25].
  • Investigation of the mt-mRNA decay after thiamphenicol treatment indicated that three transcripts (ND2, ND3 and Cyt. b) are significantly stabilized after inhibition of mitochondrial translation [26].
  • The inferred start codon of NADH2 is ATT (isoleucine) [27].
  • This region and part of the adjacent cytochrome c oxydase subunit I (COI) gene were sequenced for two crocodilian, two turtle, and one snake species and for Sphenodon punctatus; part of the adjacent nicotinamide adenine dinucleotide dehydrogenase subunit 2 (ND2) gene was also sequenced for the crocodilian and turtle species [20].
  • We provide an independent assessment of the evolutionary history of pantherine lineage using two complete mitochondrial (mt) genes (ND2 and ND4) and the nuclear beta-fibrinogen intron 7 gene, whose utility in carnivoran phylogeny was first explored [28].
