ICAM5 (Intercellular Adhesion Molecule 5)

5-Fluorouracil (5-Fu) is a cornerstone chemotherapeutic agent in the treatment of colorectal cancer (CRC)...The circular structure, stability, and subcellular localization of circ-0023919 were confirmed using a combination of approaches, including actinomycin D treatment, RNase R digestion, specific primer PCR amplification, Sanger sequencing and FISH...In this scientific study, circ-0023919 is shown to enhance the resistance of CRC cells to 5-Fu by promoting EMT. Thus, circ-0023919 is considered a potential therapeutic target for CRC treatment.

ICAM5 emerges as a promising biological marker with significant prognostic and therapeutic potential in LUAD.

ICAM5, PCYOX1 and TYMP are associated with a decreased risk of lung adenocarcinoma. Plasma proteins may become new biological markers for lung adenocarcinoma, providing new insights into the prevention and treatment of this disease.

In this study, we identified 3 tier-one genes (MCM6, C4B, CTC-463A16.1), 7 tier-two genes (C4A, HLA-DRB9, LIMS2, LINC00654, MYO7B, SIGLEC5, TIE1), and 13 tier-three genes (AC007743.1, AC147651.4, ALDH2, BTN3A2, BTNL9, CCR1, GIPC3, HLA-DQB1, ICAM5, LIMD1, PM20D1, RP11-302L19.3, RP11-768F21.1).

PLX4720 may be a suitable treatment for the high-risk patient population...Personalized therapy may play an essential role in treatment. We further investigated the role of ICAM5 in inhibiting the malignant bioactivity of LUAD cells.

The study highlights the power of integrating genomic and proteomic data through MR analysis to uncover novel therapeutic targets for lung cancer. The identified proteins, particularly ICAM5 and SFTPB, offer promising directions for future research and development of targeted therapies, demonstrating the potential to advance personalized medicine in lung cancer treatment.

Our proteome-wide MR analysis highlighted RNASET2, TFPI, VWC2, NTM, and FLT1 as potential drug targets for further clinical investigation in LUAD. However, the specific mechanisms by which these proteins influence LUAD remain elusive. Targeting these proteins in drug development holds the potential for successful clinical trials, providing a pathway to prioritize and reduce costs in LUAD therapeutics.

Knockdown of DNMT1 or DNMT3a decreased the ICAM5 expression and suppressed malignant properties of THCA cells in vitro and in vivo, which were, however, restored by further artificial ICAM5 overexpression. Collectively, this study reveals that DNMT1 and DNMT3a mediates promoter hypermethylation and transcription activation of ICAM5 in THCA, which promotes malignant progression of THCA through the MAPK signaling pathway.

Identification of novel plasma protein biomarkers provided new insights into the biology of lung cancer.

This comprehensive analysis has highlighted thirteen plasma proteins with potential roles in three site-specific cancers. Continued research in this area may reveal their therapeutic potential, particularly KDELC2, TNFRSF10B, CPNE1, and PDIA3, paving the way for more effective cancer treatments.
