Apigenin as Tumor Suppressor in Cancers: Biotherapeutic Activity, Nanodelivery, and Mechanisms With Emphasis on Pancreatic Cancer
Pancreatic cancer is the most lethal malignancy of the gastrointestinal tract. Due to its propensity for early local and distant spread, affected patients possess extremely poor prognosis. Currently applied treatments are not effective enough to eradicate all cancer cells, and minimize their migration. Besides, these treatments are associated with adverse effects on normal cells and organs. These therapies are not able to increase the overall survival rate of patients; hence, finding novel adjuvants or alternatives is so essential. Up to now, medicinal herbs were utilized for therapeutic goals. Herbal-based medicine, as traditional biotherapeutics, were employed for cancer treatment. Of them, apigenin, as a bioactive flavonoid that possesses numerous biological properties (e.g., anti-inflammatory and anti-oxidant effects), has shown substantial anticancer activity. It seems that apigenin is capable of suppressing the proliferation of cancer cells via the induction of cell cycle arrest and apoptosis. Besides, apigenin inhibits metastasis via down-regulation of matrix metalloproteinases and the Akt signaling pathway. In pancreatic cancer cells, apigenin sensitizes cells in chemotherapy, and affects molecular pathways such as the hypoxia inducible factor (HIF), vascular endothelial growth factor (VEGF), and glucose transporter-1 (GLUT-1). Herein, the biotherapeutic activity of apigenin and its mechanisms toward cancer cells are presented in the current review to shed some light on anti-tumor activity of apigenin in different cancers, with an emphasis on pancreatic cancer. © Copyright © 2020 Ashrafizadeh, Bakhoda, Bahmanpour, Ilkhani, Zarrabi, Makvandi, Khan, Mazaheri, Darvish and Mirzaei

Biosensors Based on Nanomaterials: Transducers and Modified Surfaces for Diagnostics
The use of nanoparticles has opened a new era in the development of nanobiosensors capable of achieving analytical responses that compete with the most powerful instrumental techniques. Nanobiosensors are devices that allow analytical determinations through a specific action event between an analyte ofinterest and a bio-recognition molecule. These recognition molecules as enzymes,antibodies, nucleic acids, and aptamers are studied in detail in this chapter. The role of nanomaterials in biosensors is described in a separate section since they play a central role, allowing the understanding of their physicochemical properties such as quantum confinement, surface plasmon resonance, magnetic properties, and the effect of area increase. In addition, a brief review is provided about some basic concepts for the integration of the sensor components and their function in sensing systems found in the literature. Subsequently, a classification is proposed to summarize its fundamental characteristics, mechanism of operation, analytical characteristics, advantages, and disadvantages. Then, the main nanobiosensor types found in the literature are detailed, and specific explanations are given, e.g., those based on the determination of electrical, piezoelectric, colorimetric, fluorescent, and chemiluminescent properties. Likewise, the functioning of recently developed nanobiosensors is discussed, such as those based on local (SERS). Also, the applications of nanobiosensors in different fields of biomedicine and their fundamental importance to advance in the diagnosis of multiple pathologies as cancer are detailed. Finally, we discuss the state of the art and the future perspectives of scientific development.Fil: Romero, Marcelo Ricardo. Universidad Nacional de Córdoba.
