Background/Objective: A growing number of biomedical doctoral graduates are entering the biotechnology and industry workforce, though most lack training in business practice. Entrepreneurs can benefit from venture creation and commercialization training that is largely absent from standard biomedical educational curricula. The NYU Biomedical Entrepreneurship Educational Program (BEEP) seeks to fill this training gap to prepare and motivate biomedical entrepreneurs to develop an entrepreneurial skill set, thus accelerating the pace of innovation in technology and business ventures. Methods: The NYU BEEP Model was developed and implemented with funding from NIDDK and NCATS. The program consists of a core introductory course, topic-based interdisciplinary workshops, venture challenges, on-line modules, and mentorship from experts. Here, we evaluate the efficacy of the core, introductory course, Foundations of Biomedical Startups, through the use of pre/post-course surveys and free-response answers. Results: After 2 years, 153 participants (26% doctoral students, 23% post-doctoral PhDs, 20% faculty, 16% research staff, 15% other) have completed the course. Evaluation data show self-assessed knowledge gain in all domains. The percentage of students rating themselves as either competent or on the way to being an expert in all areas was significantly higher post-course (P < 0.05). In each content area, the percentages of participants rating themselves as very interested increased post-course. 95% of those surveyed reported the course met its objectives, and 95% reported a higher likelihood of pursuing commercialization of discoveries post-course. Conclusion: NYU BEEP can serve as a model to develop similar curricula/programs to enhance entrepreneurial activity of early-stage researchers.

Cultivating a New Generation of Biomedical Entrepreneurs

Gold-von Simson, Gabrielle; Gilon-Yanai, Michal; Gillespie, Colleen; Chitale, Sadhana; Achuonjei, Joy; Cobos, Daniel
In recent years, scientific and technological advances have brought great innovation within the life sciences industry, introducing the need for entrepreneurship training for medical and engineering graduates. With this in mind, Michal Gilon-Yanai, Dr Robert Schneider and their collaborators developed an academic program designed to provide students and faculty members with the skills they need to become successful entrepreneurs. The team of collaborators includes Dr Gabrielle Gold-von Simson, an expert in implementing academic programs, and Dr Colleen Gillespie, who specialises in education, evaluation and dissemination science. Their pioneering program trains students on how to bring new biomedical technologies to the market.

A cell-penetrating peptide derived from mammalian cell uptake protein of Mycobacterium tuberculosis

Lu, Sangwei; Tager, Leah A; Chitale, Sadhana; Riley, Lee W
A Mycobacterium tuberculosis membrane protein called Mycobacterium cell entry protein (Mce1A) was previously shown to mediate the uptake of nonpathogenic Escherichia coli and latex beads by nonphagocytic mammalian cells. Here we characterize further the in vitro invasive activity of Mce1A using colloidal gold nanoparticles and fluorescent latex microspheres. Mce1A-coated colloidal gold particles induced plasma membrane invagination and entered membrane-bound compartments inside HeLa cells. Few of the protein-coated particles were also found in the cytosol compartment. Cytochalasin D and nocodazole inhibited the uptake by HeLa cells, indicating that rearrangement of both microtubules and microfilaments was necessary for the uptake. The functional domain of Mce1A for invasion was narrowed to a highly basic 22-amino acid sequence termed Inv3. A synthetic Inv3 peptide stimulated uptake of colloidal gold particles as well as latex microspheres by HeLa cells. A chimeric protein composed of Inv3 sequence at the N terminus of beta-galactosidase appeared to stain the nuclear membrane, suggesting that it entered the HeLa cell cytoplasm. These observations suggest that the cell uptake activity of Mce1A is confined to a small peptide domain located in the core region of the protein. Inv3 could be used to ferry any protein in fusion with it into mammalian cells and may serve as a potent nonviral delivery system.

Down-modulation of lung immune responses by interleukin-10 and transforming growth factor beta (TGF-beta) and analysis of TGF-beta receptors I and II in active tuberculosis

Bonecini-Almeida, M Glória; Ho, John L; Boéchat, Neio; Huard, Richard C; Chitale, Sadhana; Doo, Howard; Geng, Jiayuan; Rego, Lorena; Lazzarini, Luiz Claudio Oliveira; Kritski, Afrânio L; Johnson, Warren D; McCaffrey, Timothy A; Silva, José R Lapa e
Immune factors influencing progression to active tuberculosis (TB) remain poorly defined. In this study, we investigated the expression of immunoregulatory cytokines and receptors by using lung bronchoalveolar lavage cells obtained from patients with pulmonary TB, patients with other lung diseases (OLD patients), and healthy volunteers (VOL) by using reverse transcriptase PCR, a transforming growth factor beta (TGF-beta) bioactivity assay, and an enzyme immunoassay. TB patients were significantly more likely than OLD patients to coexpress TGF-beta receptor I (RI) and RII mRNA, as well as interleukin-10 (IL-10) mRNA (thereby indicating the state of active gene transcription in the alveolar cells at harvest). In contrast, gamma interferon (IFN-gamma) and IL-2 mRNA was seen in both TB and OLD patients. Likewise, significantly elevated pulmonary steady-state protein levels of IL-10, IFN-gamma, and bioactive TGF-beta were found in TB patients versus those in OLD patients and VOL. These data suggest that the combined production of the immunosuppressants IL-10 and TGF-beta, as well as coexpression of TGF-beta RI and RII (required for cellular response to TGF-beta), may act to down-modulate host anti-Mycobacterium tuberculosis immunity and thereby allow uncontrolled bacterial replication and overt disease. Delineating the underlying mechanisms of M. tuberculosis-triggered expression of these immune elements may provide a molecular-level understanding of TB immunopathogenesis.
