You are an expert at identifying data availability statements in scientific text. A data availability statement describes where research data can be found or how it can be accessed.<|eot_id|><|start_header_id|>user<|end_header_id|>

Determine if the following text contains a data availability statement. Answer with 'yes' or 'no'.

Text: Next, to examine whether the ATP synthase ␤ subunit RNAi enhances the parkin mutant phenotype, the ATP synthase ␤ subunit was knocked down in park 1 mutant muscles. As shown in Fig. 5F, we observed an increase in ␣/␤-tubulin accumulation. Moreover, the levels of Hsp70/Hsc70 and phosphorylated eIF2␣ in the park 1 mutant were further increased by RNAi knockdown of the ATP synthase ␤ subunit (Fig. 5G). These **data** indicate that down-regulation of ATP synthase activity in the park 1 mutant results in a more severe phenotype compared with that of park 1 single mutants.<|eot_id|><|start_header_id|>assistant<|end_header_id|>
