The Palm Collection of UNESP/FCAV - Jaboticabal, Sao Paulo State, Brazil

The palm collection of UNESP/FCAV, Jaboticabal, Sao Paulo State, Brazil, was created in 1966 with the aim to keep different palm species for research purposes and conservation of native species, especially those threatened. Native and exotic species comprise the collection, which is held at the institution, where several studies with different species and in different areas are undertaken. Nevertheless, palm seeds and seedlings are also distributed to other research centers. The botanical review of the collection began in 2003 and there are, currently, 143 species or hybrids, in a total of 331 specimens. Considering the most ancient species, the immediate identification of many of them was possible; however, for others, such as the Attalea, Orbignya, Syagrus and Scheelea genera, future morphological studies is required, like the karyotype one or using molecular markers. Many species have been introduced and many seeds have been currently investigated regarding their germination process for future inclusion in the collection. Some of the palms do not bloom; others, however, bloom, but do not bear fruits; and others bear fruits, but their seeds do not germinate. They are either young plants, fruits which are constantly attacked by insects, like the Syagrus species and hybrids, or dioecious plants.

Avaliação do padrão de metilação dos genes ESR1, ESR2 e PGR nas linhagens celulares derivadas do câncer de mama

Breast cancer has received an increasing attention because it is one of the most common cancer type and a leading cause of morbity and mortality among women worldwide. This disease has been considered as a heterogeneous condition, demonstrating a large spectrum of clinical and histopathological variability. In the last two decades, several studies have been conducted to identify new molecular markers of cancer cells, including the alterations of DNA methylation, which is the major epigenetic mechanism associated with the control of gene expression. The hypermethylation of promoter-associated CpG islands contributes to the loss of function of several cancer-related genes, including those encoding to the estrogen receptor (ESR) and progesterone receptor (PGR). This study aimed to determine the methylation patterns of CpG islands of the genes encoding the estrogen receptor α (ESR1 gene, promoters A and B), estrogen receptor β (ESR2 gene) and progesterone receptor (PGR gene, promoter A and B) in 15 cell lines derived from breast cancer. The DNA methylation analysis was based on the “Methylation Specific-Polymerase Chain Reaction” (MSP), which provides a qualitative assessment of the methylation status of a specific CpG island. The results revealed heterogeneous data: the promoter region of ESR1A showed complete methylation in one cell line (BT549) and only two cell lines showed partial methylation (MDA-MB-231 and MDA-MB-453), while the others lineages presented unmethylated alleles. The promoter region of isoform ESR1B was unmethylated in the cell lines BT549, SKBR3 and T47D; partial methylation were observed in the cell lines MDA-MB- 231, MCF-7 and ZR-75-30, while the others cell lines presented complete methylation. All lineages showed complete or partial methylation of the ESR2 gene. The methylation pattern of the promoter A of the PGR ...(Complete abstract click electronic access below)
