    The #semantic climate community: making open-source software for knowledge liberation
    (NATL INST SCIENCE COMMUNICATION-NISCAIR, 2024) Yadav, Gitanjali; Hegde, Shweata; Kumari, Renu; Kumari, Neeraj; Murray-Rust, Peter; Worthington, Simon
    #semantic Climate is an international open research community led by young Indian scientists who use Open Notebook Science to transform information into structured filtered and actionable knowledge. The key project mission is to liberate scientific climate data, making it equitable and freely accessible to everyone. The #semantic Climate community achieves this through two central activities, namely collaborative open notebook science, and citizen engagement. The first activity is research oriented and involves creation of a proof-of-concept software toolkit that uses AI over NLP to transform locked literature (such as PDF documents) into semantic, hypermedia form. This is a non-trivial task, that has haunted developers for over three decades, and the #semantic Toolkit makes complex climate reports not just easily accessible, but also processable by machines, embedded in the Global Knowledge Graph and thereby connected to multilingual resources. The second activity is where the #semantic Climate community engages citizens in climate action and awareness through interactive hackathons, open and transparent working practices, and using Git versioning. From a citizen science perspective, this includes designing community outreach activities (games), giving attribution to all participants, and engaging the wider public in the culture and practices of science (verifiable knowledge, review, data science, modern infrastructure use, etc). This article is an overview of the #semantic Climate community building efforts, and how the project employs strategies, techniques, and ideas from the fields of Open Notebook Science. The open-source software culture and projects follow UNESCO Open Science values, and knowledge justice for the Global South, towards addressing knowledge neo-colonisation.

    AI & ethics: charting a responsible future
    (NATL INST SCIENCE COMMUNICATION-NISCAIR, 2024) Yadav, Gitanjali; Munshi, Angad; Kumari, Renu; Singh, Dhananjay; Kumari, Neeraj; Munshi, Usha Mujoo
    Artificial intelligence (AI) is rapidly transforming the world, but its development and deployment raise critical ethical questions. This paper explores the key themes that emerged from a national conclave on AI and Ethics in India, bringing together industry and academic leaders. We examine the potential of AI for various sectors, with a thematic case study for the Genome Biology sector, alongside concerns about bias, privacy, and accountability. AI development and use, while underscoring the need for an ethical framework to guide its evolution, emphasizes the need for collaboration between academia and industry to develop ethical frameworks and translate principles into practical applications. In summary, ethical AI may serve as a moral framework of AI technologies to ensure that our technological capability aligns with fundamental societal values and human dignity on the road to progress. This framework by definition would not be a static set of commandments but a dynamic constantly evolving idea about the use of technologies like AI.

    Musashi-2 causes cardiac hypertrophy and heart failure by inducing mitochondrial dysfunction through destabilizing Cluh and Smyd1 mRNA
    (Springer Nature Publishing AG, 2023) Singh, Sandhya; Gaur, Aakash; Sharma, Rakesh Kumar; Kumari, Renu; Prakash, Shakti; Kumari, Sunaina; Chaudhary, Ayushi Devendrasingh; Prasun, Pankaj; Pant, Priyanka; Hunkler, Hannah; Thum, Thomas; Jagavelu, Kumaravelu; Bharati, Pragya; Hanif, Kashif; Chitkara, Pragya; Kumar, Shailesh; Mitra, Kalyan; Gupta, Shashi Kumar
    Regulation of RNA stability and translation by RNA-binding proteins (RBPs) is a crucial process altering gene expression. Musashi family of RBPs comprising Msi1 and Msi2 is known to control RNA stability and translation. However, despite the presence of MSI2 in the heart, its function remains largely unknown. Here, we aim to explore the cardiac functions of MSI2. We confirmed the presence of MSI2 in the adult mouse, rat heart, and neonatal rat cardiomyocytes. Furthermore, Msi2 was significantly enriched in the heart cardiomyocyte fraction. Next, using RNA-seq data and isoform-specific PCR primers, we identified Msi2 isoforms 1, 4, and 5, and two novel putative isoforms labeled as Msi2 6 and 7 to be expressed in the heart. Overexpression of Msi2 isoforms led to cardiac hypertrophy in cultured cardiomyocytes. Additionally, Msi2 exhibited a significant increase in a pressure-overload model of cardiac hypertrophy. We selected isoforms 4 and 7 to validate the hypertrophic effects due to their unique alternative splicing patterns. AAV9-mediated overexpression of Msi2 isoforms 4 and 7 in murine hearts led to cardiac hypertrophy, dilation, heart failure, and eventually early death, confirming a pathological function for Msi2. Using global proteomics, gene ontology, transmission electron microscopy, seahorse, and transmembrane potential measurement assays, increased MSI2 was found to cause mitochondrial dysfunction in the heart. Mechanistically, we identified Cluh and Smyd1 as direct downstream targets of Msi2. Overexpression of Cluh and Smyd1 inhibited Msi2-induced cardiac malfunction and mitochondrial dysfunction. Collectively, we show that Msi2 induces hypertrophy, mitochondrial dysfunction, and heart failure.

    Metabolomics and molecular physiology perspective for drought and salinity stress tolerance
    (Taylor & Francis Group, 2022) Jadhav, Sagar Sudam; Kumari, Renu; Mahtha, Sanjeet Kumar; Purama, Ravi Kiran; Lamba, Vinita; Yadav, Gitanjali
    Among abiotic stresses, drought and salinity are mainly affecting crop production. Reactive oxygen species are produced during most of abiotic stresses and can damage cellular components. Therefore, plants produce specific antioxidants (e.g. carotenoids, xanthophylls), metabolites (e.g. flavonoids, phenols), osmoregulatory solutes (e.g. proline, sucrose) and thylakoid stabilizing isoprenes. Plant metabolic networks are complex, and excessive demand for these stress-responsive metabolites during abiotic stress is met only by reconfiguring the metabolic network. This chapter mainly discusses drought and salt stress-specific plant metabolomic and molecular responses and gives insights into signaling network involved thereof. Metabolomics combined with conventional breeding approaches (using introgression lines) has proven to be able to map abiotic stress-responsive loci and key candidates. The role of kinases and argonautes and the prospecting of stress-responsive metabolic quantitative trait loci and alleles are also discussed. The importance of amino acid and hormone metabolism and its connection with epigenetics is reviewed.
