CEACAM6 overexpression

It decreased stromal inflammatory phenotypes and increased activated T-cell numbers in tumors. These results demonstrate that delivering BET protein degraders to tumors and their microenvironments via a CEACAM6-targeted ADC may be effective against a wide range of solid cancers.

This study established that hypoxia increased CEACAM6 which promoted gastric cancer progression by influencing GCC proliferation and motility as well as macrophage polarization.

Taken together, CEACAM6 overexpression facilitates GC progression by upregulating fatty acid uptake through SLC27A2, thereby contributing to FAO. Genetic ablation of SLC27A2 is a promising therapeutic strategy for patients with CEACAM6-positive GC.

ERK and AKT signaling and their downstream target genes were regulated by CEACAM6 and thus the treatment with AKT inhibitor capivasertib or ERK inhibitor ulixertinib mitigated the CEACAM6-induced migration. These findings demonstrate that CEACAM6 is crucially involved in gallbladder cancer progression by promoting migration and inhibiting cell adhesion through ERK and AKT signaling providing specific options for treatment of CEACAM6-positive cancers.

This article provides a review of the expression pattern, biological function and relationship with prognosis of CEACAM6 in cancer. In summary, CEACAM6 may be a valuable diagnostic biomarker and potential therapeutic target for human cancers exhibiting overexpression of CEACAM6.

We previously performed a phase II trial of P with carboplatin (C) and paclitaxel (Pxl) vs C and Pxl alone in metastatic PDAC (NCT01280058). High CEACAM6 and IFITM3 play a role in P viral infectivity across multiple pancreatic cell lines, confirming results obtained in translational datasets. Further analysis is ongoing to elucidate mechanism and identify pathways to alter expression of CEACAM6 and IFITM3 and enhance P infectivity in future trials.

• [Zr]-NY004 has good specificity and high imaging efficiency, and is characterized by high tumor-targeting uptake and a long tumor retention time as a PET molecular imaging tracer. • Therapeutic radionuclide-conjugated antibody drug [Lu]-NY004 has high uptake and prolonged uptake duration in tumors, low non-target organ uptake, and significant tumor-inhibiting efficacy in PDAC model. • The self-developed antibody structure NY004 is a promising drug platform for radioimmunotheranostics of CEACAM6-positive tumors including pancreatic ductal adenocarcinoma.

Finally, the improved antitumor effect of CDDOXL was evaluated in a metastatic BCSC mouse model via systemic administration. Collectively, our study is the first to demonstrate that a multi-functional nano complex using a novel surface biomarker of BCSC may be a more effective therapeutic agent for the treatment of cancer and CSCs.
