The PIWI-like protein 1 (PIWIL1) plays a crucial role in stem cell proliferation, embryogenesis, growth, and development, as well as differentiation and maturation in multiple organisms. The relationships between PIWIL1 expression and clinicopathological features of colorectal cancer (CRC) patients were analyzed by us. Survival analysis was performed using the Kaplan-Meier method and Cox's proportional hazards model. The high expression rate of PIWIL1 in the cancer tissue was obviously higher than that in the corresponding adjacent tissue. The expression of PIWIL1 was closely related to the tumor differentiation degree, infiltration depth, lymphovascular invasion, lymph node metastasis, and TNM stage. The Kaplan-Meier survival model suggested that the survival time of CRC patients in the high PIWIL1 expression group was notably lower than that in the low PIWIL1 expression group. High PIWIL1 expression suggests a poor prognosis for CRC patients, and PIWIL1 can serve as an important molecular marker for predicting the prognosis of CRC patients.

Germline factors are thought to function exclusively in the germline, providing the unique characteristics of germ cells. However, recent studies suggest that some of these factors may also be expressed and function outside the germline. One such example includes Vasa, a DEAD-box RNA helicase that appears to control localized translation on the spindle, facilitating efficient protein synthesis during embryogenesis of the sea urchin.

Background: Bladder cancer (BC) remains one of the most prevalent and recurrent malignancies worldwide. Identification of early biomarkers and prognostic indicators is vital for improving diagnostic accuracy and therapeutic outcomes. PIWI-interacting RNA pathway proteins (PIWILs), known regulators of gene silencing and genome stability, have emerged as potential biomarkers in various cancers.

Since its emergence in the 2000s, the study of sperm RNA has revealed their influence in sperm functions and early embryo development, positioning them as promising markers for the diagnosis of male infertility. This systematic review aimed to evaluate the potential of differentially expressed sperm mRNA associated with infertility to improve diagnostic accuracy, and to identify predictive biomarkers for successful assisted reproductive technology (ART) outcomes. A comprehensive search of the MEDLINE-PubMed database was conducted from inception to 28 April 2023, and a total of 67 eligible articles were selected.

Ribosome biogenesis is vital for sustaining stem cell properties, yet its regulatory mechanisms are obscure. Herein, we show unique properties of zebrafish mutants in which spermatogonial stem cells (SSCs) do not differentiate or upregulate rRNAs. Meioc colocalized with Piwil1 in perinuclear germ granules, but Meioc depletion resulted in Piwil1 accumulation in nucleoli.

Recent findings underscore the critical role of PIWIL/piRNA pathways in cancer, extending their known functions beyond reproductive biology. Retinoblastoma (RB), a rare pediatric retinal tumor, is primarily driven by RB1 gene loss but also involves significant epigenetic alterations. Our previous studies revealed that PIWIL4 is significantly upregulated in RB, and its knockdown disrupts the expression of stemness-associated factors, including OTX2, SOX2, and NANOG.
