PRLR (Prolactin Receptor 2)

In contrast, from days three to seven post-infection, there was significant upregulation of avidin (AVD), a biotin-binding protein, and versican (VCAN), which is linked to tissue remodelling and inflammation. These findings correlate with the disease's progression from initial liver infection to widespread bacterial presence, suggesting value as host biomarkers for effective SLD monitoring and the development of targeted therapies.

This study suggests XPD exerts therapeutic effects on HMG by modulating hormone levels. Through AMPK activation, XPD inhibits fatty acid synthesis and energy metabolism, which reduces intracellular lipid accumulation and suppresses excessive cell proliferation. Additionally, it improves cellular energy status, thereby alleviating abnormal cell proliferation caused by energy metabolic disorders. XPD also promotes autophagy by inhibiting the downstream mTOR pathway, further suppressing cell proliferation. Moreover, it inhibits VEGF expression to exert anti-angiogenic effects, reducing blood supply to hyperplastic breast tissue and restricting its growth-thus contributing to HMG treatment.

Additionally, doxorubicin plus the PRL treatment of breast cancer cells was shown in vitro to attract cytotoxic NK cells compared to the controls, and this was dependent on the PRLR. These results demonstrate that combined breast cancer cell DNA damage and PRL exposure results in the anti-tumor cell activity of asialo-GM1-positive immune cells.

Western blot analysis indicated that Osthole downregulated PRLR expression and decreased the phosphorylation of JAK2 and STAT3, suggesting the inhibition of the JAK2/STAT3 signaling pathway. These results collectively highlight the therapeutic potential of Osthole in targeting prostate cancer cells through PRLR and modulating the JAK2/STAT3 signaling pathway, warranting further clinical exploration.

The hypomyelination observed in PRLR-KO nursing pups continues into the prepubertal stage (PD28), when locomotor alterations (reduced distance traveled and decreased velocity of movements) manifest in PRLR-KO mice. These findings show that the lack of PRL signaling leads to brain hypomyelination in neonatal mice and negatively affects locomotor function at the prepubertal stage, thereby supporting the notion that PRL is required for adequate myelination during postnatal development.

Interaction models, adjusted for potential confounders, were created with different adjuvant treatment modalities: chemotherapy, radiotherapy, tamoxifen, and aromatase inhibitors...To explore potential SNP-associated effects, gene expression and transcriptional networks were analyzed in the METABRIC cohort and indicated that PRLR-low tumors were associated with reduced DNA repair signaling and enhanced anti-tumoral immunity. PRLR merits further evaluation as a putative pharmacogenomic biomarker in relation to radiotherapy for breast cancer patients.

RT-qPCR validated the anticipated levels of PVT1, miR-145-5p, and SERPINE1 in MDA-MB-231 cancer compared to MCF-10 A noncancerous cells. Taken together, the results of this work shed light on the several possible oncogenic mechanisms of PVT1, including its closely related genes and signaling pathways.

Investigations are now being conducted to determine the diagnostic and therapeutic potential of prolactin. The objective of this review is to investigate the various functions that prolactin serves, as well as the ways in which high or low amounts of the hormone influence certain cancers.

The therapeutic potential of this interplay was also evaluated in vitro using MDA-MB-231 cells, a preclinical model of human triple-negative breast cancer, where treatment with PRL and Verteporfin, an FDA-approved pharmacological YAP-inhibitor, alone or their combination suppressed the expression of the mesenchymal marker vimentin and the stem cell marker CD44 as well as reduced their Ki67 proliferative marker expression. Collectively, our results emphasize the pro-differentiation role of PRL/PRLR pathway in mammary and breast cancer cells and highlight that promoting PRL/PRLR signaling while inhibiting the YAP-CCN2 oncogenic pathway can be exploited as a differentiation-based combination therapeutic strategy in breast cancer.

Importantly, the single introduction of either a miR-34a or miR-181b mimic was able to decrease the invasion capacity of LMS cells. Our studies demonstrated that miR-34a or miR-181b may play an anti-oncogenic role in uterine tumors; further studies are needed to better understand the role and regulatory mechanism of these miRNAs in LMS cancer development, which will help provide prognostic and therapeutic options for patients with LMS.

Therefore, a biocompatible concentration range (200-1000 µg/mL) was used in C2C12 cells, where the formulation blunted the hydrogen peroxide-induced upregulation of TNFα, IL-6, RANKL, ESR1, and PRLR. Overall, the results of this study corroborate the use of the formulation for facing the oxidative stress and inflammation, which forms the basis of the osteoclastogenic process.

Among the STAT inhibitors, only nuclear PIAS3 expression correlates with PIP. In vitro studies indicated that silencing PIAS3 in T47D cells does not affect PIP expression or sensitivity to doxorubicin (DOX), but T47D control cells with a higher PIP expression are more sensitive to DOX, highlighting the need for further investigation into these mechanisms.
