A MULHER ALÉM DO BEM E DO MAL: Malévola e a representação cinematográfica do feminino integrado

Estudo sobre as construções simbólicas e identitárias da mulher presentes na narrativa e na estrutura das personagens femininas do filme Malévola (2014) – produção dos estúdios Disney (EUA). A narrativa é inspirada no conto de fadas “A Bela Adormecida do Bosque” e distingue-se pela perspectiva feminina, modificando as possibilidades de interpretação, além de possibilitar a quebra do paradigma dicotômico relacionado ao Bem e ao Mal. A pesquisa tem por objetivo estudar a evolução das construções imaginárias da mulher no cinema e traçar paralelos entre as características arquetípicas das personagens de Malévola em relação à identidade da mulher na contemporaneidade. Para tal, será tomado como referencial teórico os estudos do imaginário social, com as obras de Gilbert Durand, Edgar Morin e, em especial, Michel Maffesoli; conceitos da psicanálise a partir dos trabalhos de C.G. Jung, Erich Neumann, Marie-Louise Von Franz e Clarissa Pinkola Estés; as teorias de Stuart Hall, Laura Mulvey e Gilles Lipovetsky relacionadas aos estudos culturais com ênfase em gênero; e também o ecofeminismo através dos trabalhos de autoras como Vandana Shiva e Maria Mies. Nosso referencial teórico-metodológico é a Hermenêutica de Profundidade (HP) visando à interpretação da estrutura simbólica de nosso objeto. Resultam desta pesquisa a verificação de um processo de saturação de padrões identitários e simbólicos provindos da modernidade e a evolução de novas dinâmicas nas narrativas presentes nas mídias e na comunicação

Myc represses transcription of the growth arrest gene gas1

Cell proliferation is regulated by the induction of growth promoting genes and the suppression of growth inhibitory genes. Malignant growth can result from the altered balance of expression of these genes in favor of cell proliferation. Induction of the transcription factor, c-Myc, promotes cell proliferation and transformation by activating growth promoting genes, including the ODC and cdc25A genes. We show that c-Myc transcriptionally represses the expression of a growth arrest gene, gas1. A conserved Myc structure, Myc box 2, is required for repression of gas1, and for Myc induction of proliferation and transformation, but not for activation of ODC. Activation of a Myc-estrogen receptor fusion protein by 4-hydroxytamoxifen was sufficient to repress gas1 gene transcription. These findings suggest that transcriptional repression of growth arrest genes, including gas1, is one step in promotion of cell growth by Myc.

Rapid induction of senescence in human cervical carcinoma cells

Expression of the bovine papillomavirus E2 regulatory protein in human cervical carcinoma cell lines repressed expression of the resident human papillomavirus E6 and E7 oncogenes and within a few days caused essentially all of the cells to synchronously display numerous phenotypic markers characteristic of cells undergoing replicative senescence. This process was accompanied by marked but in some cases transient alterations in the expression of cell cycle regulatory proteins and by decreased telomerase activity. We propose that the human papillomavirus E6 and E7 proteins actively prevent senescence from occurring in cervical carcinoma cells, and that once viral oncogene expression is extinguished, the senescence program is rapidly executed. Activation of endogenous senescence pathways in cancer cells may represent an alternative approach to treat human cancers.

Selection for spiral waves in the social amoebae Dictyostelium

Starving Dictyostelium amoebae emit pulses of the chemoattractant cAMP that are relayed from cell to cell as circular and spiral waves. We have recently modeled spiral wave formation in Dictyostelium. Our model suggests that a secreted protein inhibitor of an extracellular cAMP phosphodiesterase selects for spirals. Herein we test the essential features of this prediction by comparing wave propagation in wild type and inhibitor mutants. We find that mutants rarely form spirals. The territory size of mutant strains is approximately 50 times smaller than wild type, and the mature fruiting bodies are smaller but otherwise normal. These results identify a mechanism for selecting one wave symmetry over another in an excitable system and suggest that the phosphodiesterase inhibitor may be under selection because it helps regulate territory size.
