Abstract:
We report a case of primary lung cancer with ossification. A 69-year-old woman was referred to our hospital due to an abnormal shadow on a chest roentgenogram. Chest computed tomography demonstrated an irregular mass with scattered high-density areas in the left lower lung. Excisional biopsy of the mass revealed lung adenocarcinoma, and we performed left lower lobectomy. Histologic examination revealed the tumor to be a papillary adenocarcinoma with ossification. We confirmed that bone morphogenetic protein(BMP)-2 developed from the tumor by a western blot analysis.

What is Gene Expression?
Gene expression is the process in which DNA directs the synthesis of functional products, that is, proteins. Cells can regulate gene expression at various stages. It allows organisms to generate different cell types and enables cells to adapt to internal and external factors.
Genetic Information Flows from DNA to RNA to Protein
A gene is a stretch of DNA that serves as the blueprint for functional RNAs and proteins. Since DNA is made up of nucleotides and proteins consist of amino...
