Enhanced therapeutic potential of antibody fragment via IEDDA-mediated site-specific albumin conjugation.

Background: The use of single-chain variable fragments (scFvs) for treating human diseases, such as cancer and immune system disorders, has attracted significant attention. However, a critical drawback of scFv is its extremely short serum half-life, which limits its therapeutic potential. Thus, there is a critical need to prolong the serum half-life of the scFv for clinical applications.

Enhanced anti-tumor activity of arginine decarboxylase through the incorporation of aromatic amino acids at the multimer-forming interface.

The pressing challenge of cancer's high mortality and invasiveness demands improved therapeutic approaches. Targeting the nutrient dependencies within cancer cells has emerged as a promising approach. This study is dedicated to demonstrating the potential of arginine depletion for cancer treatment.

Computation-Aided Design of Albumin Affibody-Inserted Antibody Fragment for the Prolonged Serum Half-Life.

Single-chain variable fragments (scFvs) have been recognized as promising agents in cancer therapy. However, short serum half-life of scFvs often limits clinical application. Fusion to albumin affibody (ABD) is an effective and convenient half-life extension strategy.

A case of metastatic squamous cell carcinoma arising from actinic cheilitis.

Actinic keratosis (AK) is a common, sun-induced, pre-malignant lesion with a strong likelihood of progressing to a malignancy. The reported risk of AK progressing to squamous cell carcinoma (SCC) varies from less than 1% to 20%. Clinically, induration, pain, large size, marked hyperkeratosis, ulceration, bleeding, rapid growth, and recurrence or persistence may be markers of AK progression into SCC.

A case of post-injury angiokeratoma circumscriptum of the chest.

Angiokeratomas represent vascular lesions and are histologically characterized by superficial vascular ectasia and overlying acanthosis and/or hyperkeratosis. Angiokeratomas can be classified into five types, with angiokeratoma circumscriptum representing the least common of the five types. Angiokeratoma circumscriptum presents at birth and frequently occurs unilaterally on the leg.

Formononetin promotes early fracture healing through stimulating angiogenesis by up-regulating VEGFR-2/Flk-1 in a rat fracture model.

Plant-derived phytoestrogens have bone protective effects, but the molecular mechanism behind these effects remains unclear. This study is aimed at fully characterizing the fracture healing process of formononetin, and investigating the mechanism underlying angiogenesis in calluses of a rat fracture model. Femoral fractures were produced in 2-month-old Sprague-Dawley rats.
