Background: Telomere shortening and RNA pseudo-uridylation are common features of tumors. NOP10 is a member of the H/ACA snoRNP family, essential for maintaining telomerase activity and RNA pseudouridylation. NOP10 has been indicated to be substantially expressed in tumors such as breast and lung cancers and is associated with poor prognosis. Currently, no investigation exists on NOP10 in pancreatic cancer (PC). This is the first investigation to elucidate the impact on tumorigenesis and prognostic value of NOP10 in pancreatic adenocarcinoma (PAAD).
Method: NOP10 expression and its survival prognostic significance were analyzed via clinical PAAD data from the TCGA database and NOP10 expression in other tumors from the GEPIA database. Furthermore, the NOP10 expression and survival prognosis in clinical samples were validated by qRT-PCR. In-vitro experiments were carried out to elucidate the impact of NOP10 on the biological function of PC cells.
Results: It was revealed that NOP10 expression was increased in PC tissues than in the normal pancreatic tissues. High NOP10 expression was markedly linked with poorer prognosis. NOP10 may be involved in focal adhesion, channel activity, cAMP signaling pathway, the interaction of neuroactive ligand-receptor, and cell adhesion molecules cams. NOP10 was associated with the tumour immune microenvironment and drug sensitivity. Down-regulation of NOP10 expression suppressed PC cells' ability to proliferate, migrate, and invade.
Conclusions: This investigation elucidated the prognostic and predictive importance of NOP10 in PAAD and revealed that NOP10 is associated with poor prognostic features, survival prognosis and TIME. Knockdown of NOP10 inhibits the progression of PAAD.

Aims: To build an innovative telomere-associated scoring model to predict prognosis and treatment responsiveness in acute myeloid leukemia (AML).
Background: AML is a highly heterogeneous malignant hematologic disorder with a poor prognosis. While telomere maintenance is frequently observed in tumors, investigations into telomere-related genes (TRGs) in AML remain limited.

Extracellular vesicles (EVs) contain a plethora of biomolecules, including nucleic acids, with diverse diagnostic and therapeutic application potential. Although reverse transcription-quantitative PCR (RT-qPCR) is the most widely applied laboratory technique to evaluate gene expression, its applicability in EV research is challenged by the lack of universal and stably present reference genes (RGs). In this study, we identify, validate and establish SNRPG, OST4, TOMM7 and NOP10 as RGs for the normalization of EV-associated genes by RT-qPCR.

Background: To compare the expression levels of long non-coding RNA (lncRNA) and messenger RNA (mRNA) in pre-receptive endometrium between patients with Polycystic Ovary Syndrome (PCOS)and normal ovulation undergoing in vitro fertilization-embryo transfer (IVF-ET).
Methods: Endometrial tissues were collected with endometrial vacuum curette in pre-receptive phase (3 days after oocytes retrieval) from PCOS and control groups. LncRNAs and mRNAs of endometrium were identified via RNA sequencing and alignments.
