Abstract:
In this issue of Blood Cancer Discovery, Varano and colleagues uncover a substantial fraction of high-grade B-cell lymphoma with MYC and BCL2(-BCL6) translocations (so called "double-hit" lymphomas or high-grade B-cell lymphoma-double-hit-BCL2) that lack detectable expression of the B-cell receptor. MYC translocation in these cells is mediated by RAG enzymes, induced in response to silencing of the B-cell receptor in a precursor cell, a feature that renders them resistant to polatuzumab vedotin. See related article by Varano et al., p. 364.

Tumor Progression
Colon cancer is one of the best-documented examples of tumor progression. Early mutation in the APC gene in colon cells causes a small growth on the colon wall called a polyp. With time, this polyp grows into a benign, pre-cancerous tumor. Further...

Secondary Lymphoid Organs
The spleen is a vital organ in the lymphatic system, nestled in the upper left side of the abdomen. It is composed of two primary regions: the red pulp and the white pulp, each having distinct functions. The red pulp performs a significant role in blood filtration. It efficiently purges the blood of old or damaged red blood cells and...
