Summary: | Heat shock proteins (HSPs) work in response to a variety of external and internal stresses to maintain homeostasis and are upregulated upon cellular damage. This study aimed to determine the effect of maximal aerobic effort test (
max test) on the expression of genes related to heat shock proteins’ (HSPs) cycle (
HSP90AA1
,
HSP90AB1
,
PTGES3
). Eleven black-belt taekwondo male athletes participated in this study and performed a
max test on a treadmill connected to the Cortex gas analyzer till the point of physical exhaustion. Gene expression was analyzed by real-time PCR, while the physiological parameters were measured spectrophotometrically or by immune assays using serum form the blood Before the test (Bf), Immediately After (IA), and Two Hours After (2HA) the
max test. The levels of fold change expression were affected by the VO
2
max test.
HSP90AA1
,
HSP90AB1
and
PTGES3
mRNA levels were significantly higher IA the test (
P
≤ 0.05). HSPs surpassed the cut-off value (1.5-fold) IA showed (M = 2.29 times for
HSP90AA1
), (M = 1.68 times for
HSP90AB1
), while
PTGES3
did not reach the cut-off value (M = 1.12 times). The expression levels of the three genes were significantly decreased 2HA and returned to the baseline values. Moreover, physiological parameters including growth hormone, creatinine kinase, white blood cells, platelets count, and blood lactate showed a peak in their levels IA the test and then dropped 2HA (
P
≤ 0.05). Our findings demonstrate that genetic expressions of
HSP90AA1
and
HSP90AB1
genes were significantly elevated IA the test and decreased 2HA. The same applied on most of the physiological parameters; strongly suggesting the possible utility of using those parameters as a reference to confirm evidence of exercise-induced cell stress. |
