title: New Thermodynamics Table: standard metabolic energies

description: The first sheet in this excel file is a Table that collects the standard Gibbs energies of formation (from the elements) of a large number of chemical species that are relevant for metabolism. It obtained these from a substantial number of sources, including Thauer et al and Alberty, as indicated at the bottom of the first sheet of the Table. Following Alberty, (2006) the Table also computes the further transformed Gibbs energies of formation, under the standard conditions also used by Alberty, i.e. T=298.15 K, pHc=7, pMgc=3, I=0.25 M. This involves Legendre transformations for pH and pMg, and also the computation of the apparenn Gibbs energies of formation of 'reactants' (totals of chemical species, such as ATP4-, HATP3-, H2ATP2-, MgATP2-). It further calculates the standard metabolic energies of the metabolites, as defined in an upcoming paper by Westerhoff et al. (2023) entitled 'Thermodynamics in short for analyzing the living state'. This then involves a further Legendre transformation with the chemical potential of water. The resulting standard metabolic energies can then be used to calculate the metabolic energies of metabolites, by also using their total concentration, in millimolar. No computations of activity coefficients aare needed. The metabolic energies come with a new standard which is T=310.15 K (37 C), pH=7, pMg=3, I=0.15 M and osmolarity=0.35 M and is taken to be more valid for most intracellular biology. The standard metabolic energies are dependent on these conditions and the Table enables one to calcuate the standard values for other conditions, such as T=298.15 K (25 C). Other sheets in the excelfile calculate energies of a number reactions as examples.

title: ENDGAME - Laboratory Experiment 2022-11-29 Exp. 005 - Part 3 - High Speed Camera data

description: Preliminary test with high speed camera and Schlieren shadow photography. Images of the injection of air in a 2D setup obtained using 2 parallel glass sheets (3 mm thickness) separated by rubber seals and filled with a viscous fluid. The viscous fluid is obtained mixing distilled water with a hair gel (2/3 distilled water, 1/3 hair gel). The gap between the two parallel sheets is 3 mm. Air was injected into the 2D setup through a capillary tube (~2 mm diam) with constant flow rate (~13x10<sup>-3 </sup>l/s). Frame rate of the high speed camera is 250 fps. The spherical mirror has been covered in order to acquire only optical images and compare them with the corresponding Schlieren shadow photography images (ENDGAME_LabExp_HighSpeedCamera_20221129_003_XXX and ENDGAME_LabExp_HighSpeedCamera_20221129_004_XXX).

title: Dataset related to article "Important functional role of the protein Osteopontin in the progression of malignant pleural mesothelioma"

description: This record contains raw data related to article “Important functional role of the protein Osteopontin in the progression of malignant pleural mesothelioma" Background: Malignant Pleural Mesothelioma (MPM) is an aggressive cancer of the mesothelial lining associated with exposure to airborne non-degradable asbestos fibers. Its poor response to currently available treatments prompted us to explore the biological mechanisms involved in its progression. MPM is characterized by chronic non-resolving inflammation. in this study we investigated which inflammatory mediators are mostly expressed in biological tumour samples from MPM patients.<br> Methods: Expression and quantification of Osteopontin (OPN) was detected in tumour and plasma samples of MPM patients by mRNA, immunohistochemistry and ELISA. The functional role of OPN was investigated in mouse MPM cell lines in vivo using an orthotopic syngeneic mouse model.<br> Results: In patients with MPM, the protein OPN was significantly more expressed in tumours than in normal pleural tissues and predominantly produced by mesothelioma cells; plasma levels were elevated in patients and associated with poor prognosis. However, modulation of OPN levels was not significantly different in a series of 18 MPM patients receiving immunotherapy with durvalumab alone or with pembrolizumab in combination with chemotherapy, some of whom achieved a partial clinical response. Two established murine mesothelioma cell lines: AB1 and AB22 of sarcomatoid and epithelioid histology, respectively, spontaneously produced high levels of OPN. Silencing of the OPN gene (Spp1) dramatically inhibited tumour growth in vivo in an orthotopic model, indicating that OPN has an important promoting role in the proliferation of MPM cells. Treatment of mice with anti-CD44 mAb, blocking a major OPN receptor, significantly reduced tumour growth in vivo.<br> Conclusions: These results demonstrate that OPN is an endogenous growth factor for mesothelial cells and inhibition of its signaling may be helpful to restrain tumour progression in vivo. These findings have translational potential to improve the therapeutic response of human MPM
