NCT03893617

Brief Summary

The goal of this study is to examine the impact of psychological stress on DNA integrity by conducting an experiment under controlled conditions with healthy volunteers to directly test the extent to which acute stress increases DNA damage, while simultaneously testing the blocking effects of pre-treatment with propranolol, and exploring key hypothesized mediators and moderators of the severity of the DNA damage.

Outcome Measures

Primary Outcomes (1)

  • DNA Stress Response

    Change in percent tail intensity will be measured using the Comet assay of DNA damage in blood samples

    Blood samples will be collected after a 60 minute baseline period and after the approximately 15 minute acute stress task period

Secondary Outcomes (10)

  • DNA Stress Response (8-OHdG)

    Blood samples will be collected after a 60 minute baseline period and after the approximately 15 minute task period

  • DNA Stress Response (γ-H2AX)

    Blood samples will be collected after a 60 minute baseline period and after the approximately 15 minute task period

  • Neuroendocrine Stress Response (Norepinephrine (NE))

    Blood samples will be collected after a 60 minute baseline period and during/after the approximately 15 minute task period

  • Neuroendocrine Stress Response (Epinephrine (EPI))

    Blood samples will be collected after a 60 minute baseline period and during/after the approximately 15 minute task period

  • Hematological Stress Response

    Blood samples will be collected after a 60 minute baseline period and after the approximately 15 minute task period

  • +5 more secondary outcomes

Study Arms (2)

Propranolol group

ACTIVE COMPARATOR

This group will receive a single oral dose (80mg) of propranolol in a blinded capsule during their acute stress study visit.

Drug: PropranololBehavioral: Acute stress taskBehavioral: No stress task

Placebo group

PLACEBO COMPARATOR

This group will receive a single blinded capsule containing no active medication during their acute stress study visit.

Drug: Placebo oral capsuleBehavioral: Acute stress taskBehavioral: No stress task

Interventions

A single oral dose (80mg) of propranolol will be administered in a blinded capsule at the start of the baseline monitoring period of the acute stress study visit.

Propranolol group

A single blinded capsule containing no active medication will be administered at the start of the baseline monitoring period of the acute stress study visit.

Placebo group

Participants will complete speech and arithmetic tasks, performed in front of an audience (e.g., researcher staff members) and recorded by a video camera to assess non-verbal behaviors and evaluate performance. The task will be initiated following completion of baseline sample collection during the acute stress study visit and will take approximately 15 minutes.

Placebo groupPropranolol group
No stress taskBEHAVIORAL

Participants will sit quietly for 5 minutes, read a short passage aloud for 5 minutes, and read a list of numbers aloud for 5 minutes. The task will be initiated following completion of baseline sample collection during the no stress study visit and will take approximately 15 minutes.
