    Dentifying potential drugs targeting key genes associated with glioblastoma through an in-silico approach
    (UMT Lahore, 2024-04-26) Hafiza Maria Usmani Rana
    Glioblastoma multiforme, a rare and aggressive brain disorder, has become a focal point of investigation due to its relentless growth, leading to devastating outcomes. Classified as a Grade IV neoplasm by the World Health Organization (WHO), GBM is characterized by its elusive detection, high susceptibility to coexisting health conditions, and limited treatment options. Recent attention to personalized medicine has prompted research efforts aimed at devising tailored treatment approaches based on the identification of biomarkers associated with GBM. Exploration of GBM biomarkers has garnered interest owing to their potential role in prognosis determination, which has propelled the advancement of targeted therapeutic interventions and the individualization of treatment protocols. A major and quickly-moving step forward in the treatment of glioblastoma is the disclosure of the target-based virtual drug screening technique that uses organic/natural compounds derived from plants. NPACT, a publicly available database, is being used in this project to identify potential drugs for the treatment of glioblastoma neural cancer. In this work, the assessment of a molecule's blood-brain barrier penetration is the main emphasis. Based on their favourable ADMET (distribution, metabolism, absorption, excretion, and toxicity) profiles, 10 of the 120 derivative compounds that were carefully examined were chosen. By using databases such as DisGenet and GeneCards, the study used a network-based bioinformatics technique to find candidate compounds that might be used as therapeutic agents against glioblastoma. To construct a PPI network, the pertinent genes identified in both source datasets underwent conversion into String Bioinformatics and were subsequently imported into Cytoscape. Additionally, we pinpointed the top 10 rated genes associated with GBM using the MCODE and CytoHubba Plugins. Subsequent to conducting GO annotation and KEGG pathway enrichment analysis on these hub genes, several crucial functionalities and signalling pathways closely associated with glioblastoma infections were unveiled. To identify the most suitable docked medications or pharmaceuticals based on binding energies, RMSD values, and maximal intermolecular interactions, the top-ranking genes underwent docking using Molecular Operating Environment (MOE) against ten screening drugs. Lastly, to validate the results of molecular docking we performed molecular dynamic simulation. By building artificial environments in MD simulations, we studied biological processes, chemical reactions, molecular systems, and material behaviours in controlled, realistic, and computationally tractable settings. This leads to important discoveries and advances in a wide range of scientific fields. Molecular Dynamic simulation revealed that EGFR showed best interaction with Vismione B. The interaction between Isochaihulactone and SRC is more favourable and PIK3CA showed energetically more favourable interaction with Resveratrol phytochemicals.

    This study aimed to isolate the chromium-resistant bacteria from industrial wastewater. With an increase in industries and the discharge of effluent directly without any treatment increasing pollution and contaminants day by day. Chromium contamination not only affecting our environment but also human health. Environmental pollution has a considerable negative impact on health outcomes, as proven by the fact that it is responsible for an estimated 90% of fatalities in low-income nations. In low-income countries, air and water pollution are the most prevalent. This is in contrast to the fast rising economies, where the damaging effects of chemicals and pesticides comprise the principal types of environmental contamination. So, in this study Six isolates that were chromium resistant were isolated and screened through different biochemical tests. RC3, RC5, and RC7 isolated strains showed the ability to reduce the chromium in a shorter period. MIC (minimal inhibitory concentration) further highlighted the isolates tolerance level because selected isolates showed different growth at different chromium concentrations (3mM, 5mM, 6mM, 7mM, 20mM, 22mM, and 24mM). In chromium reduction assay, selected isolates grew with 0.25mM working concentration of Cr (VI). As a result, from the six isolated bacterial isolates RC3, RC5 and RC7 showed greater reduction ability. All these results showed that these selected isolates can be used for the bioremediation of chromium.

    Zika virus is a mosquito-borne flavivirus. It is passed through the placenta to the baby and causes neurological diseases such as microcephaly, Guillain-Barre syndrome (GBS) and congenital Zika syndrome (CZS). It belongs to the Flaviviridae family and was first discovered in 1947 in a Ugandan macaque monkey. However, there is no approved vaccine for Zika virus. The recent study is design to find out a potential drug against ZIKV, we selected FDA approved drugs that can be used against different proteins of ZIKV which are essential in replication of virus and immune evasion. Current approaches may possibly consist of the use of conventional medications which are not suitable to be used for zika virus. New advance techniques are required to develop such therapeutic drug which could show more safety, efficacy and immunogenicity against ZIKV. For this purpose, 2413 FDA approved drugs were docked using auto dock vina against non-structural proteins NS1, NS2, NS5 and the envelope Protein (E). The FDA approved drug which shows the highest negative binding energy was further used for molecular dynamic simulation analysis for 100ns. During MD simulation, RMSF (Rot Mean Square Deviation), RMSD (Rot Mean Square Deviation), Rg (Radius of Gyration), HB (Hydrogen Bonding) were analyzed which showed that the protein-ligand complex is stable throughout the simulation run.

    This thesis focuses on the biotechnological potential of industrial effluent-derived alkaliphilic bacteria that have been identified and described. Microorganisms that favor high pH settings are known as alkaliphiles. In Lahore, Pakistan, they were found in untreated textile effluents. Numerous morphological, biochemical, and molecular methods, such as Gram staining, catalase and oxidase tests, and 16S rRNA gene amplification, were used to identify and characterize various bacterial strains. Finding strains that generate important industrial enzymes, including alkaline proteases and amylases, which are essential for bioremediation and the detergent business, is the study's main goal. Amylases degrade starch, but alkaline proteases efficiently remove protein-based stains from detergents. Additionally, these enzymes are essential to bioremediation since they degrade pollutants in alkaline environments. The present investigation highlights the broader implications of these discoveries and highlights the potential of alkaliphiles to tackle environmental problems, improve industrial operations, and propel scientific advancements. Through utilizing these extremophiles' special qualities, the research aims to develop long-term wastewater treatment solutions and stimulate industrial innovation. Together, these studies shed fresh light on the diversity and resilience of microbes while demonstrating the transforming power of alkaliphilic bacteria in industrial and environmental setting.
