CD36 overexpression

Second, we studied the lipid metabolic changes upon anti-BCMA exposure with Elranatamab (EL), an investigational, off-the-shelf, humanized BCMA-CD3-directed bispecific antibody engineered to elicit potent T-cell-mediated anti-MM activity. Conversely, in OPM2, inducing iron-dependent lipid peroxidation through RSL3 (3 µM) treatment rescued EL resistance, resulting in a time-dependent increase in cytosolic lipid peroxidation beginning at 6 hours, and overt cell death via ferroptosis at 18 hours. Taken together, our findings suggest that MUFA/PUFA ratio drives ferroptosis and mediates EL sensitivity, addressing lipid handling as a novel means to tailor immunotherapy in RRMM.

Furthermore, inhibition of CD36 and Nogo-B expression activated the P53-P21-Rb signaling pathway which contributed to the CD36 and Nogo-B-inhibited proliferation and migration of TNBC. Taken together, the results suggest that inhibition of CD36 and Nogo-B can reduce the proliferation and migration of TNBC, which provides new targets for the development of drugs against TNBC.

Based on the fact that CD36 is a key factor in the pathogenesis of non-alcoholic fatty liver disease (NAFLD) and subsequent hepatocellular carcinoma (HCC), the risk of developing NAFLD and HCC on long-term use of PCSK9 siRNA is thus raised as a hypothesis. Additionally, because CD36 is also involved in the promotion of malignant diseases other than HCC, such as acute myeloid leukemia, gastric cancer, breast cancer, and colorectal cancer, the speculative danger of flourishing these malignancies by PCSK9 siRNA is discussed as well.

Therefore, our central hypothesis is that inhibition of lipid metabolism will sensitize CRC cells to BRAF inhibitors and overcome acquired resistance. We established HT29 cells and primary PT130 and PT2449pt cells resistant to PLX8394, a novel BRAF inhibitor... Our study demonstrates that resistance to BRAF inhibitors is associated with a significant increase in proliferation, metastasis, and upregulation of lipid metabolism. We show that combination of FASN and BRAF inhibitors has a combinational effect on inhibiting cell viability in parental but not resistant cells, suggesting that the addition of FASN inhibitor to the standard regimen for BRAFV600E mutation positive patients can improve efficacy of these therapies. Additional screening of lipid metabolism-targeted therapies in combination with standard BRAF regimens are needed to develop novel and more efficacious strategies for CRC patients with BRAF mutations.

The knockdown of CD36 in ccRCC cells reduced lipid accumulation and also blocked the tumor-promoting effects induced by HIF-2α under hypoxia. Our findings suggest that hypoxia-dependent HIF-2α promotes the remodeling of lipid metabolism and the malignant phenotype of ccRCC via CD36, providing a certain theoretical basis for clarifying the mechanism of ccRCC.

miR-1254 attenuated the invasion and proliferation of cervical cancer cells by modulating the expression levels of CD36.

Our findings indicate that a hypoxia in the peritoneal cavity induces CD36 expression in GC cells, which contributes to PM through the uptake of FFAs.

Importantly, high expression of MMP28 leads to a significant decrease in active E-cadherin and an increase in the products of E-cadherin cleavage, CTF1 and CTF2. In summary, upregulation of CD36 expression promotes the metastatic properties of CRC via upregulation of MMP28 and an increase in E-cadherin cleavage, suggesting that targeting the CD36-MMP28 axis may be an effective therapeutic strategy for CRC metastasis.

Using flow cytometry, we confirmed overexpression of CD36, CD41, CD61 and CD226 in the LDN fraction. In summary, our data support the notion that LDNs are a unique neutrophil population and provide novel targets to clarify their role in tumor progression and their potential as diagnostic and therapeutic tool.

These findings strongly suggest that oxLDL-induced HDGF upregulation participates in subsequent LOX-1 and CD36 expression in aortic SMCs and mechanistically contributes to the formation of SMC-derived foam cells. The oxLDL/LOX-1/HDGF axis may serve as a target for anti-atherogenesis therapy.

Pretreatment of HCC cells with PI3K/AKT/mTOR inhibitors largely blocked the tumor-promoting effect of CD36. Our findings suggest that CD36 exerts a stimulatory effect on HCC growth and metastasis, through mediating aerobic glycolysis by the Src/PI3K/AKT/mTOR signaling pathway.
