A genome-scale model of Clostridium autoethanogenum reveals optimal bioprocess conditions for high-value chemical production from carbon monoxide

Clostridium autoethanogenum is an industrial microbe used for the commercial-scale production of ethanol from carbon monoxide. While significant progress has been made in the attempted diversification of this bioprocess, further improvements are desirable, particularly in the formation of the high-value platform chemicals, such as 2,3-butanediol. A new, experimentally parameterised genome scale model of C. autoethanogenum predicts dramatically increased 2,3-butanediol production under non-carbon-limited conditions when thermodynamic constraints on hydrogen production are considered

TGFbeta induces apoptosis and EMT in primary mouse hepatocytes independently of p53, p21Cip1 or Rb status

Melville Trust for the Care and Cure of Cancer to SP and SS.Background: TGF beta has pleiotropic effects that range from regulation of proliferation and apoptosis to morphological changes and epithelial-mesenchymal transition (EMT). Some evidence suggests that these effects may be interconnected. We have recently reported that P53, P21(Cip1) and pRB, three critical regulators of the G1/S transition are variably involved in TGF beta-induced cell cycle arrest in hepatocytes. As these proteins are also involved in the regulation of apoptosis in many circumstances, we investigated their contribution to other relevant TGF beta-induced effects, namely apoptosis and EMT, and examined how the various processes were interrelated. Methods: Primary mouse hepatocytes deficient in p53, p21 and/or Rb, singly or in combination were treated with TGF beta for 24 to 96 hours. Apoptosis was quantified according to morphology and by immunostaining for cleavedcapsase 3. Epithelial and mesenchymal marker expression was studied using immunocytochemistry and real time PCR. Results: We found that TGF beta similarly induced morphological changes regardless of genotype and independently of proliferation index or sensitivity to inhibition of proliferation by TGF beta. Morphological changes were accompanied by decrease in E-cadherin and increased Snail expression but the mesenchymal markers (N-cadherin, SMA alpha and Vimentin) studied remained unchanged. TGF beta induced high levels of apoptosis in p53-/-, Rb-/-, p21(cip1)-/- and control hepatocytes although with slight differences in kinetics. This was unrelated to proliferation or changes in morphology and loss of cell-cell adhesion. However, hepatocytes deficient in both p53 and p21(cip1)were less sensitive to TGF beta-induced apoptosis. Conclusion: Although p53, p21(Cip1) and pRb are well known regulators of both proliferation and apoptosis in response to a multitude of stresses, we conclude that they are critical for TGF beta-driven inhibition of hepatocytes proliferation, but only slightly modulate TGF beta-induced apoptosis. This effect may depend on other parameters such as proliferation and the presence of other regulatory proteins as suggested by the consequences of p53, p21(Cip1) double deficiency. Similarly, p53, p21(Cip1) and pRB deficiency had no effect on the morphological changes and loss of cell adhesion which is thought to be critical for metastasis. This indicates that possible association of these genes with metastasis potential would be unlikely to involve TGF beta-induced EMT.Publisher PDFPeer reviewe

Deficiency of G1 regulators P53, P21Cip1 and/or pRb decreases hepatocyte sensitivity to TGFβ cell cycle arrest

<p>Abstract</p> <p>Background</p> <p>TGFβ is critical to control hepatocyte proliferation by inducing G1-growth arrest through multiple pathways leading to inhibition of E2F transcription activity. The retinoblastoma protein pRb is a key controller of E2F activity and G1/S transition which can be inhibited in viral hepatitis. It is not known whether the impairment of pRb would alter the growth inhibitory potential of TGFβ in disease. We asked how <it>Rb</it>-deficiency would affect responses to TGFβ-induced cell cycle arrest.</p> <p>Results</p> <p>Primary hepatocytes isolated from <it>Rb-floxed </it>mice were infected with an adenovirus expressing CRE-recombinase to delete the <it>Rb </it>gene. In control cells treatment with TGFβ prevented cells to enter S phase via decreased cMYC activity, activation of P16^INK4Aand P21^Cipand reduction of E2F activity. In <it>Rb</it>-null hepatocytes, cMYC activity decreased slightly but P16^INK4Awas not activated and the great majority of cells continued cycling. <it>Rb </it>is therefore central to TGFβ-induced cell cycle arrest in hepatocytes. However some <it>Rb</it>-null hepatocytes remained sensitive to TGFβ-induced cell cycle arrest. As these hepatocytes expressed very high levels of P21^Cip1and P53 we investigated whether these proteins regulate pRb-independent signaling to cell cycle arrest by evaluating the consequences of disruption of <it>p53 </it>and <it>p21</it>^{<it>Cip1</it>}. Hepatocytes deficient in <it>p53 or p21</it>^{<it>Cip1 </it>}showed diminished growth inhibition by TGFβ. Double deficiency had a similar impact showing that in cells containing functional pRb; P21^Cipand P53 work through the same pathway to regulate G1/S in response to TGFβ. In <it>Rb</it>-deficient cells however, <it>p53 </it>but not <it>p21</it>^{<it>Cip </it>}deficiency had an additive effect highlighting a pRb-independent-P53-dependent effector pathway of inhibition of E2F activity.</p> <p>Conclusion</p> <p>The present results show that otherwise genetically normal hepatocytes with disabled <it>p53</it>, <it>p21</it>^{<it>Cip1 </it>}or <it>Rb </it>genes respond less well to the antiproliferative effects of TGFβ. As the function of these critical cellular proteins can be impaired by common causes of chronic liver disease and HCC, including viral hepatitis B and C proteins, we suggest that disruption of pRb function, and to a lesser extend P21^Cip1and P53 in hepatocytes may represent an additional new mechanism of escape from TGFβ-growth-inhibition in the inflammatory milieu of chronic liver disease and contribute to cancer development.</p

Whole genome sequence and manual annotation of Clostridium autoethanogenum, an industrially relevant bacterium

Clostridium autoethanogenum is an acetogenic bacterium capable of producing high value commodity chemicals and biofuels from the C1 gases present in synthesis gas. This common industrial waste gas can act as the sole energy and carbon source for the bacterium that converts the low value gaseous components into cellular building blocks and industrially relevant products via the action of the reductive acetyl-CoA (Wood-Ljungdahl) pathway. Current research efforts are focused on the enhancement and extension of product formation in this organism via synthetic biology approaches. However, crucial to metabolic modelling and directed pathway engineering is a reliable and comprehensively annotated genome sequence

New Insight into the Antifibrotic Effects of Praziquantel on Mice in Infection with Schistosoma japonicum

Schistosomiasis is a parasitic disease infecting more than 200 million people in the world. Although chemotherapy targeting on killing schistosomes is one of the main strategies in the disease control, there are few effective ways of dealing with liver fibrosis caused by the parasite infection in the chronic and advanced stages of schistosomiasis. For this reason, new strategies and prospective drugs, which exert antifibrotic effects, are urgently required.-induced liver fibrosis was inhibited by PZQ treatment for 30 days. Furthermore, we analyzed the effects of praziquantel on mouse primary hepatic stellate cells (HSCs). It is indicated that mRNA expressions of Col1α1, Col3α1, α-SMA, TGF-β, MMP9 and TIMP1 of HSCs were all inhibited after praziquantel anti-parasite treatments.The significant amelioration of hepatic fibrosis by praziquantel treatment validates it as a promising drug of anti-fibrosis and offers potential of a new chemotherapy for hepatic fibrosis resulting from schistosomiasis

Clinical Sequencing Exploratory Research Consortium: Accelerating Evidence-Based Practice of Genomic Medicine

Despite rapid technical progress and demonstrable effectiveness for some types of diagnosis and therapy, much remains to be learned about clinical genome and exome sequencing (CGES) and its role within the practice of medicine. The Clinical Sequencing Exploratory Research (CSER) consortium includes 18 extramural research projects, one National Human Genome Research Institute (NHGRI) intramural project, and a coordinating center funded by the NHGRI and National Cancer Institute. The consortium is exploring analytic and clinical validity and utility, as well as the ethical, legal, and social implications of sequencing via multidisciplinary approaches; it has thus far recruited 5,577 participants across a spectrum of symptomatic and healthy children and adults by utilizing both germline and cancer sequencing. The CSER consortium is analyzing data and creating publically available procedures and tools related to participant preferences and consent, variant classification, disclosure and management of primary and secondary findings, health outcomes, and integration with electronic health records. Future research directions will refine measures of clinical utility of CGES in both germline and somatic testing, evaluate the use of CGES for screening in healthy individuals, explore the penetrance of pathogenic variants through extensive phenotyping, reduce discordances in public databases of genes and variants, examine social and ethnic disparities in the provision of genomics services, explore regulatory issues, and estimate the value and downstream costs of sequencing. The CSER consortium has established a shared community of research sites by using diverse approaches to pursue the evidence-based development of best practices in genomic medicine

Coping With Colorectal Cancer: A Qualitative Exploration With Patients and Their Family Members

Background. Extensive family coping research has been conducted among breast cancer, prostate cancer and melanoma with lesser emphasis on the coping experiences of colorectal cancer (CRC) patients and their family members. Objective. To examine ways in which patients and their family members cope with the diagnosis of CRC. Methods. A total of 73 participants (21 patients, 52 family members) from 23 families described their experiences during and after a CRC diagnosis, including their coping experiences with the diagnosis. Data from semi-structured interviews were audio recorded and transcribed. The data were analyzed utilizing content analysis with inductive coding methods. Results. Eight major themes were identified: positive reframing, holding on to a sense of normalcy, religion and spirituality, joining a group, creating awareness of CRC, lifestyle change, seeking information and alternative treatments. Maintaining an emotional sense of normalcy through positive thinking, engaging in activities to take one’s mind off the diagnosis and believing that there is a higher authority which has control over the diagnosis and life were vital for the patients and their family members. Patients and family members used similar coping strategies. Conclusion. Findings from this study have implications for understanding how families blend emotion-based and problem-focused coping strategies in the face of a CRC diagnosis. Further developing evidence-based interventions that target coping and well-being in cancer patients and extending them to family members is necessary and holds great promise for providers who care for patients with familial cancers

Culture negative mitral valve endocarditis caused by Neisseria gonorrhoeae confirmed by 16S rDNA sequence analysis of resected valvular tissue

Infective endocarditis is a dynamic disease with changing epidemiology and diagnostic strategies. Culture negative endocarditis poses a particular problem for clinicians regarding appropriate antimicrobial therapy and adequate duration of therapy. Utilization of nucleic acid amplification techniques and subsequent sequencing has provided clinicians an alternative to traditional phenotypic microbial identification which has been extremely useful in identification of fastidious organisms. We report a case of a young male with culture negative native mitral valve endocarditis and subsequent 16S rDNA sequencing of Neisseria gonorrhoeae from excised valvular tissue and embolic material. Identification of this organism with novel nucleic acid amplification and 16S rDNA sequence analysis techniques permitted targeted antibiotic therapy and successful treatment of this potentially fatal disease
