“…Several recent biogeographic studies of various subtropical disjunct lineages (e.g. Paederia [Nie et al, ], Isodon [Yu et al, ], Diplazium [Wei et al, ], and Uvaria [Zhou et al, ]) have inferred scenarios of long distance dispersal between East Asia and Mediterranean‐Africa. The various mechanisms proposed to explain these long distance dispersal scenarios (e.g., cross‐oceanic dispersal and animal dispersal) may bear reinvestigation in light of our study, which provides strong evidence that a warm, humid forest zone along the margin of the Himalaya and the core region of the Tibet provided a dispersal corridor(s) for biotic exchange within Eurasia during the Oligocene into the early Neogene.…”

Aim Many subtropical organisms exhibit an East Asian‐Tethyan disjunction, a distribution split between East Asia and the Mediterranean. The underlying mechanisms and timing have remained unclear to date. The evolutionary history of Quercus section Ilex Loudon, a representative East Asian‐Tethyan disjunct lineage with a rich and widespread fossil record, was investigated to understand the key drivers of this disjunction. Location Eurasia. Methods The phylogeny of Quercus section Ilex was reconstructed using RAD‐seq. Divergence times were estimated based on three fossil calibrations. Ancestral range and niche were reconstructed on the calibrated tree to infer the timing of transitions in geographic distributions and niche. Convergence in ecological space was estimated by fitting alternative multiple‐regime Ornstein‐Uhlenbeck models. Leaf shape affinities among extant and fossil taxa of section Ilex were assessed using geometric morphometric approaches. Results Six clades were well resolved in section Ilex. Ancestral range reconstruction and divergence time dating suggest a wide distribution along the East Tethys seaway, with initial divergence at the mid‐Eocene, and all six clades originating before the Miocene. The section dispersed from East Asia to the Mediterranean at the Eocene‐Oligocene boundary. A shift toward higher elevations was detected in the Himalayan clade during the middle or late Miocene. European fossil lineages during the early Miocene differ in leaf morphology from later lineages, which we infer to be a consequence of adaptive differentiation or species turnover. Main conclusions Quercus section Ilex was widespread along the East Tethys seaway from the middle Eocene onward. The European holly oaks originated from an East Asian ancestral lineage that dispersed to Europe via the Tibet‐Himalaya corridor in the Oligocene. Lowlands along the margins of the Himalayas and through an Oligocene Tibetan valley served as the dispersal route(s) for these species. Changing climates drove Miocene extinction and local adaptation of European lineages.

“…There are three possibilities of concerted evolution for two different copies in an individual ( Alvarez & Wendel, 2003;Koch et al, 2003): fixation of one copy and loss of the other one, mixture of the two copies forming a new genotype, or maintenance of two copies with heterozygous sites. Therefore, incongruence between markers from different genomes, integrating with the observed heterozygous sites, offers an opportunity to detect speciation through hybridization (e.g., Sang & Zhong, 2000;Kim & Donoghue, 2008;Russell et al, 2010;Yu et al, 2014;Xiang et al, 2015), although we cannot completely rule out the possibility of ILS in this study. In the second situation, a hybrid species may form a distinct clade in phylogenetic trees where it is difficult to identify its parental donors.…”

Speciation, the evolutionary process forming new species, is a key mode generating biodiversity on the Earth. In this study, we produced a species‐level phylogeny of Roscoea using one nuclear ribosomal and two chloroplast DNA fragments based on Bayesian inference and maximum likelihood. We then explored the possible speciation processes using the species‐level phylogeny and the heterozygous sites in the nuclear DNA. The incongruence between nuclear and chloroplast phylogenies, and several heterozygous sites in the nuclear DNA, suggested that R. auriculata might have a hybrid origin with R. purpurea and R. alpina being two possible parental progenitors; however, one alternative possibility through incomplete lineage sorting cannot be ruled out. In addition, R. kunmingensis likely originated from R. tibetica Batalin through the process of “budding speciation”. These results provided a valuable framework to draw testable hypotheses for future in‐depth comparative studies to further our understanding of the underpinning speciation and adaptation mechanisms that contribute to ultrahigh biodiversity in the Himalayas and the Hengduan Mountains.

“…Indeed, acute alcohol exposure (binge drinking), is the major pattern of drinking. Acute alcohol exposure, especially when achieving high blood alcohol concentration of 0.08% or more [40], may also cause alcoholic hepatitis, liver cirrhosis, and increased death rates which can be sudden [41, 42]. This suggests that binge alcohol exposure experiments are of great interest and can also be used as an indicator or predictor of the pathogenesis of AFLD.…”

Role of CYP2E1 in Mitochondrial Dysfunction and Hepatic Injury by Alcohol and Non-Alcoholic Substances

Alcoholic fatty liver diseases (AFLD) and non-alcoholic fatty liver diseases (NAFLD) are two pathological conditions that are spreading worldwide. Both conditions are remarkably similar with regards to the pathophysiological mechanism and progression despite different causes. Oxidative stress-induced mitochondrial dysfunction through post-translational protein modifications and/or mitochondrial DNA damage has been a major risk factor in both AFLD and NAFLD development and progression. Cytochrome P450-2E1 (CYP2E1), a known important inducer of oxidative radicals in the cells, has been reported to remarkably increase in both AFLD and NAFLD. Interestingly, CYP2E1 isoforms expressed in both endoplasmic reticulum (ER) and mitochondria, likely lead to the deleterious consequences in response to alcohol or in conditions of NAFLD after exposure to high fat diet (HFD) and in obesity and diabetes. Whether CYP2E1 in both ER and mitochondria work simultaneously or sequentially in various conditions and whether mitochondrial CYP2E1 may exert more pronounced effects on mitochondrial dysfunction in AFLD and NAFLD are unclear. The aims of this review are to briefly describe the role of CYP2E1 and resultant oxidative stress in promoting mitochondrial dysfunction and the development or progression of AFLD and NAFLD, to shed a light on the function of the mitochondrial CYP2E1 as compared with the ER-associated CYP2E1. We finally discuss translational research opportunities related to this field.
