It is well admitted that the link between chronic inflammation and cancer involves cytokines and mediators of inflammatory pathways, which act during the different steps of tumorigenesis. The cyclooxygenases (COXs) are a family of enzymes, which catalyze the rate-limiting step of prostaglandin biosynthesis. This family contains three members: ubiquitously expressed COX- 1, which is involved in homeostasis; the inducible COX-2 isoform, which is upregulated during both inflammation and cancer; and COX-3, expressed in brain and spinal cord, whose functions remain to be elucidated. COX-2 was described to modulate cell proliferation and apoptosis mainly in solid tumors, that is, colorectal, breast, and prostate cancers, and, more recently, in hematological malignancies. These findings prompt us to analyze here the effects of a combination of COX-2 inhibitors together with different clinically used therapeutic strategies in order to further improve the efficiency of future anticancer treatments. -

Abbreviations used: PCD, programmed cell death; ROS, reactive oxygen species; GAPDH, glyceraldehyde-3-phosphate dehydrogenase; ER, endoplasmic reticulum; MS, mass spectrometry. 1email [email protected] Abstract A variety of proteases have been implicated in yeast PCD including the metacaspase, Mca1 and the separase Esp1, the HtrA-like serine protease Nma111, the cathepsin-like serine carboxypeptideases and a range of vacuolar proteases. Proteasomal activity is also shown to have an important role in determining cell fate, with both pro- and anti-apoptotic roles. Caspase-3, -6- and -8 like activities are detected upon stimulation of yeast PCD, but not all of this activity is associated with Mca1, implicating other proteases with caspase-like activity in the yeast cell death response. -

The Role of Caspase-2 in Regulating Cell Fate
cells Review The Role of Caspase-2 in Regulating Cell Fate Vasanthy Vigneswara and Zubair Ahmed * Neuroscience and Ophthalmology, Institute of Inflammation and Ageing, University of Birmingham, Birmingham B15 2TT, UK; [email protected] * Correspondence: [email protected] Received: 15 April 2020; Accepted: 12 May 2020; Published: 19 May 2020 Abstract: Caspase-2 is the most evolutionarily conserved member of the mammalian caspase family and has been implicated in both apoptotic and non-apoptotic signaling pathways, including tumor suppression, cell cycle regulation, and DNA repair. A myriad of signaling molecules is associated with the tight regulation of caspase-2 to mediate multiple cellular processes far beyond apoptotic cell death. This review provides a comprehensive overview of the literature pertaining to possible sophisticated molecular mechanisms underlying the multifaceted process of caspase-2 activation and to highlight its interplay between factors that promote or suppress apoptosis in a complicated regulatory network that determines the fate of a cell from its birth and throughout its life. Keywords: caspase-2; procaspase; apoptosis; splice variants; activation; intrinsic; extrinsic; neurons 1. Introduction Apoptosis, or programmed cell death (PCD), plays a pivotal role during embryonic development through to adulthood in multi-cellular organisms to eliminate excessive and potentially compromised cells under physiological conditions to maintain cellular homeostasis [1]. However, dysregulation of the apoptotic signaling pathway is implicated in a variety of pathological conditions. For example, excessive apoptosis can lead to neurodegenerative diseases such as Alzheimer’s and Parkinson’s disease, whilst insufficient apoptosis results in cancer and autoimmune disorders [2,3]. Apoptosis is mediated by two well-known classical signaling pathways, namely the extrinsic or death receptor-dependent pathway and the intrinsic or mitochondria-dependent pathway. -
