Latest Research Progress on ROR1

Identifying targets that are expressed on tumor cells but not or lowly expressed in normal cells is crucial for tumor immunity. ROR1 is a highly promising drug target, exhibiting differentiated high expression in various solid tumors and hematologic malignancies, while not expressing in adult healthy tissues. This suggests that ROR1 holds the potential to become […]

AXL activation initiates the signal transduction of various downstream pathways, such as PI3K/AKT, MAPK/ERK, and PKC.

Can AXL Break Through in Tumor Immunotherapy with Setbacks in AXL-ADC?

At the end of 2020, Genmab and ADC Therapeutics announced the termination of clinical development for Enapotamab vedotin and ADCT-601, respectively, due to their failure to meet expected outcomes in early trials. Both drugs were antibody-drug conjugates (ADCs) targeting AXL. Enapotamab vedotin was coupled with the microtubule inhibitor MMAE, while ADCT-601 was coupled with the […]

The structure of the 5T4 protein includes an extracellular region, a transmembrane domain (356-376 aa), and an intracellular domain,

Unlocking Multiple Biologic Therapeutic Avenues with 5T4 – A Solid Tumor Target

The 5T4 protein, also known as Wnt-activated inhibitory factor 1 (WAIF1) or Trophoblast Glycoprotein (TPBG), is a glycoprotein found in embryonic trophoblast cells. It has been identified as a treatment target for solid tumors due to its abundance in cancerous tissues and limited expression in normal tissues. Currently, there are approximately nine investigational drugs targeting […]

Unlocking the Secrets of Antibody-Drug Conjugates: Inside the World of Antibody Internalization

Antibody-drug conjugates (ADCs) mainly consist of monoclonal antibodies, linkers, and cytotoxic payloads. The antibody, acting as the “missile” in ADC drugs, possesses target-specific functionality. It can selectively recognize tumor cell surface antigens, undergo internalization upon binding to these antigens, and deliver the cytotoxic payload to tumor cells to exert its toxic effects. Since not all […]

The TROP2 protein comprises four distinct segments, including 323 amino acids: 1-26 amino acids as a hydrophobic signal peptide, 27-274 amino acids as the extracellular domain, 275-297 amino acids as the transmembrane domain, and 298-323 amino acids as the cytoplasmic tail.

Advances in TROP2-ADC Drug Research

Tumor-Associated Calcium Signal Transducer 2 (TROP2), also known as TACSTD2 and EGP-1, is a surface antigen found in numerous solid tumors. It has become a pivotal target for pharmaceutical giants spurring a race in drug development in the world. Currently, TROP2-targeting biopharmaceuticals are predominantly concentrated in the Antibody-Drug Conjugate (ADC). Based on incomplete statistics, there are 11 TROP2-targeting […]

CEACAMs, short for carcinoembryonic antigen-related cell adhesion molecules, constitute a family of cell surface glycoproteins encompassing 12 distinct members: CEACAM1, CEACAM3, CEACAM4, CEACAM5, CEACAM6, CEACAM7, CEACAM8, CEACAM16, CEACAM18, CEACAM19, CEACAM20 and CEACAM21. These proteins are classified within the immunoglobulin superfamily of adhesion molecules, and they share structural similarities with unique variations.

CEACAM5, an emerging target for cancer therapy

Human carcinoembryonic antigen-related cell adhesion molecule 5 (CEACAM5), initially discovered in colon cancer by Gold and Freeman in 1965 [1] [2], has long served as a pivotal tumor marker for clinical detection and diagnosis of colorectal cancer. Recent advancements in CEACAM5 research have unveiled its potential as a target for developing novel cancer therapeutics. Notably, […]

CLDN6 has four transmembrane domains, a short cytoplasmic N-terminus, a C-terminal cytoplasmic domain, two extracellular domains (larger ECL1 and a smaller ECL2) and a short intracellular loop. ECL1 and the PDZ-binding domain at the cytoplasmic C-terminus are characteristic domains of CLDNs.

CLDN6, the next promising target for solid tumor therapy after ClDN18.2?

In June 2023, BioNTech presented the first human trial data of BNT211 at the American Society of Clinical Oncology (ASCO). BNT211 is a CLDN-6-targeting CAR-T cell therapy in combination with a CLDN6-encoding mRNA vaccine (CARVac). mRNA vaccines stimulate the expansion of CAR-T cells in the patients’ body by inducing the expression of CLDN6 on the surface of antigen-presenting cells, […]
