LPAR5 (Lysophosphatidic Acid Receptor 5)

We developed a useful risk model and this study provided new insights for OS therapy.

The enhanced accumulation of Lpar5-/- P14 cells during the acute phase of Clone 13 infection appears to be regulated by Lpar5-mediated changes in T-cell survival and not through trafficking or proliferation. RNA sequencing analyses and surface phenotyping show that Lpar5 likely regulates CD8 T-cell exhaustion through modulation of NK receptor expression, including the CD94/NKG2A inhibitory axis.

Mouse lung cancer LL/2 cells also showed increased growth in response to LPA when cultured with the co-culture supernatant, and this effect was inhibited by AM966 and TC LPA5 4, and promoted by GRI-977143. These findings suggest that co-culture of SVEC4-10 and 3T3 cells more effectively promotes lung cancer cell growth through LPA receptor signaling than either cell type alone.

Bioinformatics and machine learning techniques identified the common genes "RXRG, CDH2, ETV5, QPCT, LRP4, FN1, and LPAR5" as PTC biomarkers, providing novel reference markers for the diagnosis and treatment of PTC patients. The model is anticipated to possess significant predictive value and assist in the early diagnosis and screening of clinical PTC. These insights enhance the field of PTC management and offer guidance for future research.

LPAR5, CYP2C18, SERPINH1 and ACSL5 may serve as potential diagnostic, prognostic, and therapeutic targets for PDAC.

LPAR2 and PLPP2 inhibition are also predicted to have potential therapeutic utility. Future multi-omics investigations are necessarily to validate which LPA signaling components are high-value candidates for pharmacological manipulation in PDAC treatment.

Viability of DLD-1 cells to fluorouracil (5-FU) in SVEC4-10 cell supernatants increased at 21 % O2 and decreased at 1 % O2. Additionally, the LPA2 agonist GRI-977143 increased viability to 5-FU. These findings indicate that LPA receptor signaling plays a critical role in regulating the biological behaviors of DLD-1 cells co-cultured with SVEC4-10 cells under hypoxic conditions.

The identification of a new epitope and apoptosis-related genes that relate to the induction of apoptosis by mAb MT99/3 may serve as a new therapeutic target for T-ALL. The anti-CD99 mAb clone MT99/3 might be a candidate for further development of a therapeutic antibody for T-ALL therapy.

This study represents the first systematic investigation into the chemical composition of Pule'an Tablets, shedding light on the potential mechanisms underlying their efficacy in treating prostatitis. These findings could serve as a valuable reference for future pharmacological research on Pule'an Tablets.

Our study provides hint evidence that LPAR1 and LPAR5 increase the MM cell-surface expression of GPRC5D and improve the efficacy of anti-GPRC5D CAR T-cell therapy, which might be as novel GPCR partners of GPRC5D for the efficient CAR-T therapy of multiple myeloma.

Additionally, ATX was significantly correlated with inflammatory gene signatures, including a CD8+ cytolytic score in multiple lung adenocarcinoma patient data sets, suggesting that an activated tumor-immune microenvironment upregulates ATX and thus provides an opportunity for cotargeting to prevent acquired resistance to anti-PD-1 treatment. These data reveal the ATX/LPA axis as an immunosuppressive pathway that diminishes the immune checkpoint blockade response in lung cancer.

Tumors high in LPAR5 and LPAR6 had the highest cytolytic activity scores, indicating decreased immune system evasion. Overall, our findings suggest that potential compensatory signaling via competing receptors must be considered in LPAR inhibitor therapy.
