PBX1: a key character of the Hallmarks of Cancer Rafaela Nasser Veiga; Jaqueline Carvalho de Oliveira; Daniela Fiori Gradia Journal of Molecular Medicine, v. 1, p. 1 2021 DOI Palavra-chave: PBX1; cancer hallmarks; pioneer factor; Biomarkers Áreas do conhecimento: Ciências Biológicas; Genética Humana e Médica; Ciências Biológicas; Genética; Biologia Molecular resumo ... Pre-B-cell leukemia homeobox transcription factor 1 (PBX1) was first identified as part of a fusion protein resulting from the chromosomal translocation t(1;19) in pre-B cell acute lymphoblastic leukemias. Since then, PBX1 has been associated with important developmental programs, and its expression dysregulation has been related to multifactorial disorders, including cancer. As PBX1 overexpression in many cancers is correlated to poor prognosis, we sought to understand how this transcription factor contributes to carcinogenesis, and to organize PBX1’s roles in the hallmarks of cancer. There is enough evidence to associate PBX1 with at least five hallmarks: sustaining proliferative signaling, activating invasion and metastasis, inducing angiogenesis, resisting cell death, and deregulating cellular energetics. The lack of studies investigating a possible role for PBX1 on the remaining hallmarks made it impossible to defend or refute its contribution on them. However, the functions of some of the PBX1’s transcription targets indicate a potential engagement of PBX1 in the avoidance of immune destruction and in the tumor-promoting inflammation hallmarks. Interestingly, PBX1 might be a player in tumor suppression by activating the transcription of some DNA damage response genes. This is the first review organizing PBX1 roles into the hallmarks of cancer. Thus, we encourage future studies to uncover the PBX1’s underlying mechanisms to promote carcinogenesis, for it is a promising diagnostic and prognostic biomarker, as well as a potential target in cancer treatment.

Performing under pressure: esterification activity of dry fermented solids in subcritical and supercritical CO2 Dominicky Cristina Serrano; Marcos Lúcio Corazza; MITCHELL, DAVID ALEXANDER; KRIEGER, NADIA BIOTECHNOLOGY LETTERS, v. 43, p. 503-509, 2021 DOI Palavra-chave: Fermentação em estado sólido; sólidos fermentados; CO2 Supercrítico; esterificação Áreas do conhecimento: Ciências Biológicas; Bioquímica dos Microorganismos; Biotecnologia resumo ... Lipases are often used in immobilized form, but commercial immobilized lipases are costly. An alternative is to produce lipases in solid-state fermentation, dry the solids and then use the “dry fermented solids” (DFS) directly. We produced DFS by growing Burkholderia contaminans on a mixture of sugarcane bagasse and sunflower seed meal and used the DFS to esterify oleic acid with ethanol in subcritical and supercritical CO2 at 40 °C. Compared to a control without CO2 at atmospheric pressure, subcritical CO2 at 30 bar improved esterification activity 1.2-fold. Higher pressures, including supercritical pressures up to 150 bar, reduced activity to less than 80% of the control. At 30 bar, the esterification activity was improved a further 1.8-fold with the addition of 9% water (i.e. 9 g water per 100 g oleic acid) to the reaction medium. A subcritical CO2 atmosphere, with the addition of a small amount of water, improved the esterification activity of DFS containing lipases of Burkholderia contaminans.
