Massive Loss of Transcription Factors Promotes the Initial Diversification of Placental Mammals. Int J Mol Sci 2022; 23:ijms23179720. [PMID: 36077118 PMCID: PMC9456351 DOI: 10.3390/ijms23179720] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 07/25/2022] [Revised: 08/22/2022] [Accepted: 08/23/2022] [Indexed: 11/17/2022] Open
Abstract
As one of the most successful group of organisms, mammals occupy a variety of niches on Earth as a result of macroevolution. Transcription factors (TFs), the fundamental regulators of gene expression, may also have evolved. To examine the relationship between TFs and mammalian macroevolution, we analyzed 140,821 de novo-identified TFs and their birth and death histories from 96 mammalian species. Gene tree vs. species tree reconciliation revealed that placental mammals experienced an upsurge in TF losses around 100 million years ago (Mya) and also near the Cretaceous–Paleogene boundary (K–Pg boundary, 66 Mya). Early Euarchontoglires, Laurasiatheria and marsupials appeared between 100 and 95 Mya and underwent initial diversification. The K-Pg boundary was associated with the massive extinction of dinosaurs, which lead to adaptive radiation of mammals. Surprisingly, TF loss decelerated, rather than accelerated, molecular evolutionary rates of their target genes. As the rate of molecular evolution is affected by the mutation rate, the proportion of neutral mutations and the population size, the decrease in molecular evolution may reflect increased functional constraints to survive target genes.

Front Psychiatry 2022; 13:976439.

Abstract
BACKGROUND Mounting studies have investigated impairments in social cognitive domains (including theory of mind [ToM] and facial emotion recognition [FER] in adult patients with temporal lobe epilepsy (TLE). However, to date, inconsistent findings remain. METHODS A search of PubMed, Web of Science, and Embase databases was conducted until December 2021. Hedges g effect sizes were computed with a random-effects model. Meta-regressions were used to assess the potential confounding factors of between-study variability in effect sizes. RESULTS The meta-analysis included 41 studies, with a combined sample of 1,749 adult patients with TLE and 1,324 healthy controls (HCs). Relative to HCs, adult patients with TLE showed large impairments in ToM (g = -0.92) and cognitive ToM (g = -0.92), followed by medium impairments in affective ToM (g = -0.79) and FER (g = -0.77). Besides, no (statistically) significant differences were observed between the magnitude of social cognition impairment in adult with TLE who underwent and those who did not undergo epilepsy surgery. Meta-regressions exhibited that greater severity of executive functioning was associated with more severe ToM defects, and older age was associated with more severe FER defects. CONCLUSIONS Results of this meta-analysis suggest that adult patients with TLE show differential impairments in the core aspects of social cognitive domains (including ToM and FER), which may help in planning individualized treatment with appropriate cognitive and behavioral interventions.

Jiang Y, Zhu M, Yu F, Wang K. Impaired empathy in patients with idiopathic generalized epilepsy: An event-related potentials study. Epilepsy Behav 2020; 111:107274. [PMID: 32693373 DOI: 10.1016/j.yebeh.2020.107274] [Citation(s) in RCA: 2] [Impact Index Per Article: 0.5] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 11/19/2019] [Revised: 06/17/2020] [Accepted: 06/17/2020] [Indexed: 10/23/2022]
Abstract
PURPOSE Epilepsy is a common neurological disorder that may be complicated by neurobehavioral comorbidities. In a previous study, we identified impairment of empathy in patients with idiopathic generalized epilepsy (IGE). However, the temporal processing of empathy in patients with IGE is not well understood. METHODS We investigated empathy for pain and self-reported empathy in 21 patients with IGE and 22 healthy control subjects. All study participants were required to complete a pain empathy task involving images of individuals in pain and neutral conditions during recording of event-related potentials. RESULTS Compared with the controls, the patients with IGE showed impaired cognitive empathy but intact emotional empathy on the Chinese version of the Interpersonal Reactivity Index; they also had normal N1, N2, and late positive potential (LPP) but lower P3 amplitudes evoked by depictions of pain in others when compared with neutral images during the pain judgment task; the difference in the effects of pain empathy on the pain task between the IGE group and the control group was statistically significant. CONCLUSION These results indicate that later processing of pain empathy is impaired but early processing is intact in patients with IGE. The present study extends the findings of our previous behavioral study by providing solid evidence of impaired empathy in patients with IGE at the neural processing level.

Goodman AM, Allendorfer JB, Heyse H, Szaflarski BA, Eliassen JC, Nelson EB, Storrs JM, Szaflarski JP. Neural response to stress and perceived stress differ in patients with left temporal lobe epilepsy. Hum Brain Mapp 2019; 40:3415-3430. [PMID: 31033120 DOI: 10.1002/hbm.24606] [Citation(s) in RCA: 7] [Impact Index Per Article: 1.4] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 10/19/2018] [Revised: 03/21/2019] [Accepted: 04/14/2019] [Indexed: 01/28/2023] Open
Abstract
Patients with epilepsy are often able to predict seizure occurrence subsequent to an acute stress experience. However, neuroimaging investigations into the neural basis of this relationship or the potential influence of perceived life stress are limited. The current study assessed the relationship between perceived stress and the neurobehavioral response to stress in patients with left temporal lobe epilepsy (LTLE) and healthy controls (HCs) using heart rate, salivary cortisol level, and functional magnetic resonance imaging and compared these effects between HCs and LTLE. Matched on perceived stress levels, groups of 36 patients with LTLE and 36 HCs completed the Montreal Imaging Stress Task, with control and stress math task conditions. Among LTLEs, 27 reported that prior (acute) stress affected their seizures (LTLES+), while nine did not (LTLES-). The results revealed that increased perceived stress was associated with seizure frequency in LTLE. Further, cortisol secretion was greater in LTLE, but did not vary with perceived stress as observed in HCs. A linear mixed-effects analysis revealed that as perceived stress increased, activation in the hippocampal complex (parahippocampal gyrus and hippocampus) decreased during stressful math in the LTLES+, increased in HCs, but did not vary in the LTLES-. Task-based functional connectivity analyses revealed LTLE differences in hippocampal functional connectivity with sensory cortex specific to stressor modalities. We argue that the current study demonstrates an inhibitory hippocampal mechanism underlying differences in resilience to stress between HCs and LTLE, as well as LTLE patients who report stress as a precipitant of seizures.
