ASC1 is a cell cycle regulator associated with severe and mild forms of myopathy.

Recently, the ASC-1 complex has been identified as a mechanistic link between ALS and spinal muscular atrophy (SMA), and three mutations of the ASC-1 gene TRIP4 have been associated with SMA or congenital myopathy. Our goal was to define ASC-1 neuromuscular function and the phenotypical spectrum associated with TRIP4 mutations.


Cathepsin L induced PC-12 cell apoptosis via activation of B-Myb and regulation of cell cycle proteins.

Cathepsin L (CTSL), a cysteine protease, is responsible for the degradation of a variety of proteins. It is known to participate in neuronal apoptosis associated with abnormal cell cycle. However, the mechanisms underlying CTSL-induced cell apoptosis remain largely unclear. We reported here that rotenone caused an activation of CTSL expression in PC-12 cells, while knockdown of CTSL by small interfering RNAs or its inhibitor reduced the rotenone-induced cell cycle arrest and apoptosis. Moreover, elevation o...

miR‑221‑3p promotes the cell growth of non‑small cell lung cancer by targeting p27.

Emerging evidence suggests the critical function of microRNAs in regulating the growth of cancer cells. In the present study, it was demonstrated that miR‑221‑3p was overexpressed in non‑small cell lung cancer (NSCLC) tissues and cell lines compared with that noted in the normal controls. Downregulation of miR‑221‑3p suppressed the proliferation, colony formation and invasion of NSCLC cells. To further understand the molecular mechanisms underlying the potential oncogenic function of miR‑221‑3...


Correlation between tcdB gene PCR cycle threshold and severe Clostridium difficile disease.

A retrospective study, including all samples tested for Clostridium difficile from 2015 to 2018, was conducted. 222 and 199 patients were respectively classified as having a mild/moderate or severe disease. A C ≤ 26 was significantly associated with severe disease. Furthermore, low C values were significantly associated to older patients and leukocytosis.

The RNA-binding protein SRSF1 is a key cell cycle regulator via stabilizing NEAT1 in glioma.

The relevance of RNA processing has been increasingly recognized in a variety of diseases. We previously identified serine/arginine-rich splicing factor 1 (SRSF1) as an oncodriver in glioma via splicing control. However, its splicing-independent roles and mechanisms are poorly defined in glioma. In this study, by integrating the data mining of SRSF1-co-expressed genes, SRSF1-affected genes and experimental studies, we demonstrated that SRSF1 was the most highly expressed SRSF in the 9 tumor types tested, an...

Regulation of CHK1 by the Ubiquitin-Proteasome System.

The checkpoint kinase 1 (CHK1) is a master regulator of genome integrity in vertebrate cells. Despite its important cell cycle functions, its regulation is still incompletely understood. Cassidy et al. provide novel insights on the regulation of the CHK1 abundance by the HECT E3 ligase HUWE1 during unperturbed cell cycle as well as in response to replicative stress. These results may help us to apprehend the underlying mechanism of tumorigenesis.

BRAP: a novel regulator of the cardiomyocyte cell cycle controlling both proliferation and survival?

Cortisol and IgA are Involved in the Progression of Alzheimer's Disease. A Pilot Study.

It is known that stress and immune systems are related with Alzheimer's disease (AD). However, the relationship of both systems in the progression of disease is not clearly demonstrated. Hair cortisol and salivary immunoglobulin A (IgA) were quantified in 49 patients with mild, moderate, and severe AD. A significant change was seen in both molecules as AD progressed from mild to moderate and severe. Low levels of cortisol were observed in mild AD patients compared with moderate and severe. However, IgA show...

Cell cycle dynamics in the reprogramming of cellular identity.

Reprogramming cellular identity is fundamentally at odds with replication of the genome: cell fate reprogramming requires complex multi-dimensional epigenomic changes, whereas genome replication demands fidelity. In this review, we discuss how the pace of genome's replication and cell cycle influences the way daughter cells take on their identity. We highlight several biochemical processes that are pertinent to cell fate control, whose propagation into the daughter cells should be governed by more complex m...

Modeling of Cisplatin-Induced Signaling Dynamics in Triple-Negative Breast Cancer Cells Reveals Mediators of Sensitivity.

Triple-negative breast cancers (TNBCs) display great diversity in cisplatin sensitivity that cannot be explained solely by cancer-associated DNA repair defects. Differential activation of the DNA damage response (DDR) to cisplatin has been proposed to underlie the observed differential sensitivity, but it has not been investigated systematically. Systems-level analysis-using quantitative time-resolved signaling data and phenotypic responses, in combination with mathematical modeling-identifies that the acti...

Organising the cell cycle in the absence of transcriptional control: Dynamic phosphorylation co-ordinates the Trypanosoma brucei cell cycle post-transcriptionally.

The cell division cycle of the unicellular eukaryote Trypanosome brucei is tightly regulated despite the paucity of transcriptional control that results from the arrangement of genes in polycistronic units and lack of dynamically regulated transcription factors. To identify the contribution of dynamic phosphorylation to T. brucei cell cycle control we have combined cell cycle synchronisation by centrifugal elutriation with quantitative phosphoproteomic analysis. Cell cycle regulated changes in phosphorylati...

Smad7 Regulates Dental Epithelial Proliferation during Tooth Development.

Tooth morphogenesis involves dynamic changes in shape and size as it proceeds through the bud, cap, and bell stages. This process requires exact regulation of cell proliferation and differentiation. Smad7, a general antagonist against transforming growth factor-β (TGF-β) signaling, is necessary for maintaining homeostasis and proper functionality in many organs. While TGF-β signaling is widely involved in tooth morphogenesis, the precise role of Smad7 in tooth development remains unknown. In this study, ...

A Prospective, Longitudinal Observation of the Incidence, Treatment, and Survival of Late Acute and Chronic Graft-versus-host disease by National Institutes of Health Criteria in a Japanese cohort.

In order to prospectively validate the incidence, manifestations, and outcomes of graft-versus-host disease (GVHD) by NIH criteria, we recruited 406 hematopoietic stem cell transplantation recipients at 16 transplant centers in Japan from May 2012 to June 2014. The 2-year cumulative incidence of late acute and chronic GVHD was 3.2% (N = 13) and 35.4% (N = 145), with a median onset of 3.6 and 4.7 months after transplant, respectively. The global severity at onset was mild in 30.3%, moderate in 43.5%,...

Liquid biopsy of cerebrospinal fluid identifies neuronal pentraxin receptor (NPTXR) as a biomarker of progression of Alzheimer's disease.

Background Alzheimer's disease (AD) is the most prevalent form of dementia. Currently, the most studied biomarkers of AD are cerebrospinal fluid (CSF) amyloid β 1-42, total tau and phosphorylated tau. However, misdiagnosis can exceed 20%. Recently, we found that CSF amyloid β precursor-like protein-1 (APLP1) and neuronal pentraxin receptor (NPTXR) are promising biomarkers of AD. The aim of the present study is to validate CSF APLP1 and NPTXR as biomarkers of AD severity. Methods APLP1 and NPTXR concentrat...

Dynamic transcriptome profiling in DNA damage-induced cellular senescence and transient cell-cycle arrest.

Cellular senescence is an irreversible cell cycle arrest process associated with aging and senescence-related diseases. DNA damage is an extensive feature of cellular senescence and aging. Different levels of DNA damage could lead to cellular senescence or transient cell-cycle arrest, but the genetic regulatory mechanisms determining cell fate are still not clear. In this work, high-resolution time course analysis of gene expression in DNA damage-induced cellular senescence and transient cell-cycle arrest w...

E2F1 activates MFN2 expression by binding to the promoter and decreases mitochondrial fission and mitophagy in HeLa cells.

Mitofusin-2 (MFN2) is primarily involved in mitochondrial fusion and participates in diverse biological processes. Several reports show that MFN2 is a target of different miRNAs; however, the transcriptional regulation of MFN2 has not been extensively studied. To gain insight into the transcriptional regulation of MFN2, we expressed E2F1 exogenously and observed that it increased the endogenous expression of MFN2 by binding to its putative promoter region. Although the levels of E2F1 were shown to vary duri...

The role of Beclin 1 in IR-induced crosstalk between autophagy and G2/M cell cycle arrest.

Beclin 1 is a well-established core mammalian autophagy protein. Autophagy has been demonstrated to play roles in cellular responses to DNA damage, such as cell cycle regulation and apoptosis. In the present study, we investigated the exact mechanism by which Beclin 1 acts as a bridge between autophagy and cell cycle, when cells are exposed to ionizing radiation (IR).

Cortical and commissural defects upon HCF-1 loss in Nkx2.1-derived embryonic neurons and glia.

Formation of the cerebral cortex and commissures involves a complex developmental process defined by multiple molecular mechanisms governing proliferation of neuronal and glial precursors, neuronal and glial migration, and patterning events. Failure in any of these processes can lead to malformations. Here, we study the role of HCF-1 in these processes. HCF-1 is a conserved metazoan transcriptional co-regulator long implicated in cell proliferation and more recently in human metabolic disorders and mental r...

Inference of the High-Level Interaction Topology between the Metabolic and Cell-Cycle Oscillators from Single-Cell Dynamics.

Recent evidence suggests that the eukaryotic metabolism is an autonomous oscillator. Together with oscillating elements of the cyclin/CDK machinery, this oscillator might form a coupled oscillator system, from which cell-cycle control emerges. The topology of interactions between the metabolic oscillator and the elements of the cyclin/CDK machinery, however, remains unknown. Using single-cell metabolic and cell-cycle dynamics in yeast, and solving an inverse problem with a system of Kuramoto oscillators, w...

Association of the Polymorphism of rs1799822 on Carnitine Palmitoyltransferase II Gene with Severe Enterovirus 71 Encephalitis in Chinese Children.

Mutations of the CPT2 gene cause CPT2 deficiency and affect the β-oxidation of fatty acids. This study examined the consequence of a polymorphism of rs1799822 in the CPT2 gene with respect to EV71 encephalitis in Chinese children. The study included 406 cases of both mild and severe EV71 infection diagnosed by RT-PCR, together with controls (n = 348). We used an improved multiplex ligation detection reaction technique to detect the polymorphism of rs1799822 in the CPT2 gene. The frequency of the (AG+GG)...

Mutations in the low-density lipoprotein receptor (LDLR), which cause familial hypercholesterolemia (FH), present a variable clinical FH phenotype. To date, over 1600 FH-causing mutations have been found worldwide. The aim of this study was to investigate the structure-function relationships of LDLR mutations by using homology modeling. Structural analysis of 36 missense mutations of known receptor activity (33 severe, 1 mild, and 2 non-pathogenic phenotypes) using sequence comparison and homology modeling ...

Long noncoding RNA ARHGAP27P1 inhibits gastric cancer cell proliferation and cell cycle progression through epigenetically regulating p15 and p16.

Long noncoding RNAs (lncRNAs) have emerged as important regulators in the development and progression of gastric cancer (GC). ARHGAP27P1 is a pseudogene-derived lncRNA, and it has been found to be associated with GC in our preliminary study, but this association has not been studied further. Herein, we confirmed that ARHGAP27P1 was significantly downregulated in GC tissues, plasma and cells. Low expression of ARHGAP27P1 was closely associated with advanced TNM stage, increased invasion depth and lymphatic m...

CC-122 as monotherapy and in combination with other agents is being evaluated for multiple indications including hematologic malignancies and advanced solid tumors. Given that renal clearance is one of the major routes of elimination for CC-122 and its clearance/exp...

DREAM and RB cooperate to induce gene repression and cell-cycle arrest in response to p53 activation.

Most human cancers acquire mutations causing defects in the p53 signaling pathway. The tumor suppressor p53 becomes activated in response to genotoxic stress and is essential for arresting the cell cycle to facilitate DNA repair or to initiate apoptosis. p53-induced cell cycle-arrest is mediated by expression of the CDK inhibitor p21WAF1/Cip1, which prevents phosphorylation and inactivation of the pocket proteins RB, p130, and p107. In a hypophosphorylated state, pocket proteins bind to E2F factors forming ...
