Key Event Components

The KE, as defined by a set structured ontology terms consisting of a biological process, object, and action with each term originating from one of 14 biological ontologies (Ives, et al., 2017; https://aopwiki.org/info_pages/2/info_linked_pages/7#List). Biological process describes dynamics of the underlying biological system (e.g., receptor signalling).Biological process describes dynamics of the underlying biological system (e.g., receptor signaling).  The biological object is the subject of the perturbation (e.g., a specific biological receptor that is activated or inhibited). Action represents the direction of perturbation of this system (generally increased or decreased; e.g., ‘decreased’ in the case of a receptor that is inhibited to indicate a decrease in the signaling by that receptor).  Note that when editing Event Components, clicking an existing Event Component from the Suggestions menu will autopopulate these fields, along with their source ID and description.  To clear any fields before submitting the event component, use the 'Clear process,' 'Clear object,' or 'Clear action' buttons.  If a desired term does not exist, a new term request may be made via Term Requests.  Event components may not be edited; to edit an event component, remove the existing event component and create a new one using the terms that you wish to add.  Further information on Event Components and Biological Context may be viewed on the attached pdf.

Key Event Description

A description of the biological state being observed or measured, the biological compartment in which it is measured, and its general role in the biology should be provided. More help

Mucus hypersecretion is a physiological response to inhalation exposures to pollutants or infectious agents. As such, it is typically of short duration and does not pose a major problem to normal lung function. Under chronic stress/exposure conditions, airway remodeling and mucus hypersecretion will cease being a physiological stress response aimed at eliminating the potential hazard and regaining the balance of a healthy airway epithelium, and chronic mucus hypersecretion will ensue. This is the case in many respiratory diseases that feature a chronic inflammatory micoenvironment such as chronic obstructive pulmonary disease and asthma (Evans et al., 2009; Allinson et al., 2016). Recent estimates of chronic mucus hypersecretion in the global population range from 3.5 to 27% (Kim et al. 2011; Martinez et al. 2014; Montes De Oca et al. 2012).

How It Is Measured or Detected

A description of the type(s) of measurements that can be employed to evaluate the KE and the relative level of scientific confidence in those measurements.These can range from citation of specific validated test guidelines, citation of specific methods published in the peer reviewed literature, or outlines of a general protocol or approach (e.g., a protein may be measured by ELISA). Do not provide detailed protocols. More help

To our knowledge, there is no report regarding the assessment of chronic mucus hypersecretion in vitro. This is most likely related to the fact that many in vitro studies are of short duration, employing acute exposures to mucus-inducing stimuli. However, mucus hypersecretion is a feature of animal models of asthma (Shim et al., 2001; Singer et al., 2004; Song et al., 2016) and occurs in mice and rats following inhalation of e.g. acrolein and cigarette smoke (Deshmukh et al., 2008; Yang et al., 2012; Chen et al., 2013; Vlahos and Bozinovski, 2015; Liu et al., 2017). There appears to be no consensus as to the "chronicity" of mucus hypersecretion, and no standardized measure exists.

Clinically, coughing and sputum production for >3 months in at least two consecutive years is defined as (chronic) mucus hypersecretion (Vestbo, 2002). More recently, questionnaires such as the St George’s Respiratory Questionnaire (Hardin and Rennard, 2015), the COPD Assessment Test (CAT) (Stott-Miller et al., 2020) and the American Thoracic Society Questionnaire (Cassidy et al., 2015) have been employed to evaluate cough and sputum production, and hence mucus hypersecretion. At times, sputum volumes are recorded as measure of mucus production. Current clinical practice, however, does not include a quantitative measure of mucus hypersecretion.

Domain of Applicability

A description of the scientific basis for the indicated domains of applicability and the WoE calls (if provided).  More help

Mucus hypersecretion was described in mice and rats following ovalbumin challenge (Shim et al., 2001; Singer et al., 2004; Song et al., 2016) or exposure to acrolein and cigarette smoke (Deshmukh et al., 2008; Yang et al., 2012; Chen et al., 2013; Vlahos and Bozinovski, 2015; Liu et al., 2017). Chronic mucus hypersecretion is also frequently found in long-term smokers, COPD patients with chronic bronchitis and asthma patients (Danahay and Jackson, 2005).
