Enhancement of Recombinant Human Endostatin on the Radiosensitivity of Human Pulmonary Adenocarcinoma A549 Cells and Its Mechanism

Table 4

A549 cell apoptosis under different conditions.

Groups	Apoptosis rate (%)
	Normoxia	Hypoxia
Control	15.9±0.57	16.7±0.67
Radiotherapy	42.7±0.37^*	30.1±0.95^∆
Endostar	19.9±0.48	26.7±0.62
Endostar + radiotherapy	41.5±0.38^*	36.3±0.71^∆

Note: ^*indicates 𝐹=1.22, 𝑃=0.479 in comparison between radiotherapy group and endostar + radiotherapy group under normoxia. ^∆indicates 𝐹=3.34, 𝑃=0.036 in comparison between radiotherapy group and endostar + radiotherapy group under hypoxia.
