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: PEDF is localized in human testicular biopsy tissue, particularly the extracellular matrix and the cells of the tubular wall [48]. PEDF has been reported to be responsible for the development and maintenance of the avascular nature of seminiferous tubules, which are important for orderly spermatogenesis [48]. Our **data** show that PAL increased CYP-induced downregulation of testicular PEDF, which indicates that PAL contributes to the avascular nature of seminiferous tubules and spermatogenesis.<|eot_id|><|start_header_id|>assistant<|end_header_id|>
