This study aimed to explore the role of small nucleolar RNA host gene 14 (SNHG14) in the pathogenesis of diffuse large-B-cell lymphoma (DLBCL). DLBCL cell lines (OCI-Ly7 and OCI-Ly3) and specimens from patients were collected to evaluate the roles of SNHG14 in DLBCL pathogenesis. The results showed that SNHG14 expression increased and miR-152-3p expression decreased in DLBCL tissues and cell lines, indicating a negative correlation between miR-152-3p and SNHG14 expression. Moreover, SNHG14 was found to promote DLBCL growth, migration, and EMT-like processes , and directly inhibits miR-152-3p gene expression sequestration of the miR-152-3p transcripts in DLBCL. Additionally, SNHG14/miR-152-3p inhibits apoptosis and promotes cell proliferation on cytotoxic T lymphocytes (CTLs) in DLBCL the PD-1/PD-L1 checkpoint. Furthermore, both the immune escape and progression of DLBCL are advanced by SNHG14 expression its interactions with miR-152-3p. Collective, this suggests that SNHG14 is a potential diagnostic, prognostic, and therapeutic target for DLBCL.

Roles of SNORD115 and SNORD116 ncRNA clusters during neuronal differentiation.

Nat Commun

In the snoRNA host gene SNHG14, 29 consecutive introns each generate SNORD116, and 48 tandem introns encode SNORD115. Loss of SNORD116 expression, but not of SNORD115, is linked to the neurodevelopmental disease Prader-Willi syndrome. SNORD116 and SNORD115 resemble box C/D small nucleolar RNAs (snoRNAs) but lack known targets.

Background: Infertility is a reproductive health problem that attracts worldwide attention. Polycystic ovary syndrome (PCOS) is a major cause of female infertility and patients with obesity and PCOS are particularly common in clinical practice. Long non-coding RNA (lncRNAs) are a functional core in cells that regulate gene expression, transcription, and chromatin modification processes, and participate in epigenetics, cell cycle, and cell differentiation.

Background: Genetic alterations have important roles in cancer development and progression. (spindle and kinetochore associated complex subunit 2) is a mitotic component that plays a critical role in maintaining the silence of the metaphase plate and spindle checkpoint. However, the exact role of in hepatocellular carcinoma (HCC) remains unclear.

Purpose: This study explored the clinical value of long non-coding RNA small nucleolar RNA host gene 14 (SNHG14) in diabetic kidney disease (DKD) and the mechanism of renal tubular injury.

Methods: Patients with DKD, type 2 diabetes mellitus (T2DM) and healthy individuals (HVs) were included, as well as the human proximal tubular epithelial cell line (HK-2) induced by high glucose was also included. The mRNA levels of SNHG14 in the serum and cells were detected using RT-qPCR.
