Copper-Induced Stimulation of Ectophosphatase Activity of Candida albicans

  • Anita Leocadio Freitas-Mesquita,
  • Fabiano Ferreira Esteves and
  • José Roberto Meyer-Fernandes

Candida albicans is an opportunistic fungal pathogen that can cause superficial and life-threatening infections, particularly in immunocompromised individuals. Its ability to adhere to host cells is critical for colonization and infection. In this co...

Biochemical Properties and Possible Roles of Ectophosphatase Activities in Fungi

  • Anita Leocadio Freitas-Mesquita and
  • José Roberto Meyer-Fernandes

6 February 2014

Ectophosphatases are surface membrane-bound proteins whose active sites face the extracellular medium. These enzymes have been reported in several microorganisms including a large number of medically relevant fungal species. An effective technique fo...

Biochemical Properties of the Acid Ectophosphatase Activity of Phytomonas serpens Involved in Cell Proliferation

  • Luiz Fernando Carvalho-Kelly,
  • Anita Leocadio Freitas-Mesquita,
  • Thaís Souza Silveira Majerowicz and
  • José Roberto Meyer-Fernandes

Phytomonas is the only kinetoplastid that can parasitize plants, causing economically relevant issues. Phytomonas serpens share similarities with pathogenic trypanosomatids, including surface enzymes that are involved in adhesion to the salivary glan...

Hypoxia Modulates Transmembrane Prostatic Acid Phosphatase (TM-PAP) in MCF-7 Breast Cancer Cells

  • Marco Antonio Lacerda-Abreu,
  • Luiz Fernando Carvalho-Kelly and
  • José Roberto Meyer-Fernandes

23 February 2025

In MCF-7 breast cancer cells, transmembrane prostatic acid phosphatase (TM-PAP) plays a critical role in tumor progression, particularly under hypoxic conditions. In this study, the impact of hypoxia on ectophosphatase activity in MCF-7 cells was exa...
