The research group Bioproducts’ Production and Purification Lab (BioPPuL), located in the Department of Bioprocesses and Biotechnology of the FCFAr of UNESP, offers a postdoctoral fellowship to develop the recombinant microorganism for the production of L-asparaginase (ASNase) and studies of its production process by submerged cultivation.
About the project
Getting older is the biggest risk factor for most fatal diseases, including cancer, heart disease and Alzheimer’s. The advances in nanomedicine comprise the development of nanoparticles either for drug delivering or as platforms for biomolecules purification. Simultaneously, continuous progresses have been made for the development of recombinant therapeutic enzymes, namely L-asparaginase (LA), which presents antineoplastic properties for thetreatment of leukaemia’s, in particular for Acute Lymphoblastic Leukemia (ALL). Currently, the LA available in medical applications is produced from bacteria. However, this type of LA may activate the immunological system causing human hypersensitivity reactions. Therefore, the search for novel microorganisms able to produce LA with no side effects has been the main focus of many researches.
Considering the great demand for the development of new technologies for the purification of therapeutic enzymes, still limited by their high cost, this project aims to produce recombinant LA by bacteria fermentation and to developa cost-effective and sustainable platform for the biopharmaceutical purification (downstream processing) from the fermentation broth using nanomaterials. The main goal is to obtain recoveries of LA above 90% and purity levels over 95%, with a cost reduction around 20%. A critical evaluation of the best strategies and conditions for the integrationprocesses and scale-up will be explored.
The involved research teams (CICECO, FEUP and UNESP) have shown to be successful in providing pioneering scientific results on the production of enzymes and on the development of separation and purification techniques for biopharmaceuticals. The UNESP team from Brazil will optimise noveltechniques of heterologous enzyme production by bacterial fermentation, which is generally regarded as safe (GRAS) and easy to manipulate, in order to achieve higher enzyme yields. The Portuguese teams (CICECO and FEUP) will be responsible for the preparation of functionalisation of silica and carbon nanomaterials, which will be used as an efficient and fast strategy for LA purification from the fermentation medium. NanoPurAsp aims to meet the approval of biopharmaceuticals by regulatory authorities which require effective and high quality biopharmaceuticals, i.e., no side-effects, high purity and biological activity. These can only be attained through in-depth knowledge of the products and of their manufacturing processes. The advanced research here produced will certainly allow the success of therapeutic enzymes production and its easy scalability up to industrial levels at a lower cost. The integrated process developed will have a great impact in economy with a long-term impact in human healthcare. This project aspires the optimization of resources and materials which will contribute to a greener and sustainable growth, which in turn will be a source of economic valorisation for the future industrial manufacturing.

Post-doctoral Fellowship in Parasitology
The opportunity is for the project belonging to the Institutional Research Development Plan (PDIP), whose objective will be the development of scientific and technological solutions that will provide rapid and timely responses to strengthen laboratory actions in health surveillance. Project title: “Pre-clinical study of new candidate drugs against leishmaniasis”, coordinated by Dr. Andre Gustavo Tempone.
The present proposal aims to identify an approved drug by means of the drug repositioning or synthetic active compound based in a natural prototype, which presents promising anti-Leishmania infantum activity. The investigator will initially perform in vitro phenotypic assays using the intracellular amastigote model of Leishmania infantum to determine the activity of the compounds to be tested. Studies will be carried out in different cell lines to evaluate the mammalian cytotoxicity. Cellular studies, based on flow cytometry techniques, spectrofluorimetry and transmission electron microscopy will be used to investigate the possible mechanisms of action of the most promising compounds. Finally, in vitro pharmacokinetic studies (ADME) such as solubility, membrane permeability and metabolization will be performed as initial parameters for the design of animal model efficacy studies.
Pre-requisites for the position: Doctoral degree in area related to the project based on Drug Discovery in visceral leishmaniasis or Chagas disease; project experience involving techniques of phenotypic assays (intracellular amastigotes and cytotoxicity), experience in studies of cellular action mechanism; experience in pharmacokinetic profile studies and in vivo efficacy studies.
Candidates need to send an e-mail to the researcher Dr. Andre G. Tempone ([email protected] ), containing curriculum vitae, letters of presentation justifying the interest in the vacancy and letters of recommendation with contacts (name, institution, telephone and e-mail) of two researchers who can give information about the candidate.
The project will be funded by São Paulo Research Foundation – FAPESP (www.fapesp.br/en ). The vacancy is open to Brazilians and foreigners. The selected will receive FAPESP Post-Doctoral Fellowship (www.fapesp.br/en/postdoc ) in the amount of BRL7,373.10 per month and Technical Reserve. The Technical Reserve of PD Grant is equivalent to 15% of the annual value of the scholarship and is intended to meet unforeseen expenses directly related to the research activity.
