Inhibiting HnRNP L-mediated alternative splicing of EIF4G1 counteracts immune checkpoint blockade resistance in Castration-resistant prostate Cancer.

Immunotherapy with checkpoint inhibitors produced significant clinical responses in a subset of cancer patients who were resistant to prior therapies. However, Castration-resistant prostate cancer (CRPC) is seriously lack of T cell infiltration, which greatly limits the clinical application of immunotherapy, but the mechanism is unclear. In the present study, in silico analyses and experimental data show that HnRNP L was significantly negatively correlated with CD4+ and CD8+ T cells infiltration in patients; besides, we found deficiency of HnRNP L recruites CD4+ and CD8+ T cells infiltration and impairs tumorigenesis.

TIPARP as a prognostic biomarker and potential immunotherapeutic target in male papillary thyroid carcinoma.

Background: Male patients with papillary thyroid carcinoma (PTC) tend to have poorer prognosis compared to females, partially attributable to a higher rate of lymph node metastasis (LNM). Developing a precise predictive model for LNM occurrence in male PTC patients is imperative. While preliminary predictive models exist, there is room to improve accuracy.

However, the underlying mechanisms behind how it exerts some effect on prostate cancer, as an extra-intestinal tumor, in a contact-independent way remain elusive and deserve exploration. Antibiotic exposure, one of the various factors affecting the gut microbiota community and capable of causing gut dysbiosis, is associated with multiple disorders.

N6-methyladenosine demethylase FTO suppressed prostate cancer progression by maintaining CLIC4 mRNA stability.

The fat mass and obesity-associated protein (FTO) is an N6-Methyladenosine (m6A) demethylase, which has been revealed to play critical roles in tumorigenesis. However, its role in the development and progression of prostate cancer (PCa) remains poorly understood. Here, we aimed to investigate the function and clinical relevance of FTO in PCa.

Abrogation of HnRNP L enhances anti-PD-1 therapy efficacy diminishing PD-L1 and promoting CD8 T cell-mediated ferroptosis in castration-resistant prostate cancer.

Owing to incurable castration-resistant prostate cancer (CRPC) ultimately developing after treating with androgen deprivation therapy (ADT), it is vital to devise new therapeutic strategies to treat CRPC. Treatments that target programmed cell death protein 1 (PD-1) and programmed death ligand-1 (PD-L1) have been approved for human cancers with clinical benefit. However, many patients, especially prostate cancer, fail to respond to anti-PD-1/PD-L1 treatment, so it is an urgent need to seek a support strategy for improving the traditional PD-1/PD-L1 targeting immunotherapy.

LncRNA SNHG1 and RNA binding protein hnRNPL form a complex and coregulate CDH1 to boost the growth and metastasis of prostate cancer.

The interaction between LncRNA and RNA-binding protein (RBPs) plays an essential role in the regulation over the malignant progression of tumors. Previous studies on the mechanism of SNHG1, an emerging lncRNA, have primarily focused on the competing endogenous RNA (ceRNA) mechanism. Nevertheless, the underlying mechanism between SNHG1 and RBPs in tumors remains to be explored, especially in prostate cancer (PCa).
