Review of "An update on molecular biology and drug resistance mechanisms of multiple myeloma"


The overall structure of the article will be discussed in this post.

Multiple myeloma is a type of cancer that affects plasma cells by making them multiply numerously especially in the bone marrow. Plasma cells become cancerous and begin to affect the immune system, the bone, and the number of platelets in the body. In this article, “An update on molecular biology and drug resistance mechanisms of multiple myeloma”, the focus is on the different mechanisms that are known to cause the disease, the developments on the resistances against drugs, and ways in which all of this can be overcome.

 The article is set-up by giving some background of the disease, transitions onto the various ways multiple myeloma can develop, and then describes how it has been found to be drug and treatment resistant.

 The reader is presented with a lot of information within the first paragraphs that can become overwhelming and most of all confusing. It just keeps mentioning one thing after another without really explaining one concept coherently. The reader is left with questions like “where did this information come from” or “how is this issue relevant or being addressed”. However, since the title does say it is an update, it leads the reader to believe that there might be another article that was published before this one which may be able to answer or clear up any confusions.

On the other hand, the article is able to better describe the resistant mechanisms of multiple myeloma. It mentions the drugs that have been effective like melphalan, but also informs the reader of how it can have negative effects by damaging bone marrow stem cells. Therefore, although the article lacks structure and clarity in some sections, it makes up for it in others. A suggestion would be to divide the article into two so that the concepts can be explained better and independently.

  2. What other drugs are effective against this disease?

    1. Hey Lauren, some other drugs include prednisone, doxorubicin, vincristine, bortezomib, and mitoxantrone. However, although somewhat effective the drug resistance is still developed.

  3. What are some of the molecular techniques they are using to diagnose or treat this disease?

    1. The disease involves abnormal growth rate of myeloma cells and production of monoclonal proteins. The article mentions three methods of diagnosing the disease: the eldest method is During/Salmon staging system which is used lab test results (like a check-list); in 2005 a "three-ekleyelim stage classification" was developed which uses the levels of serum B2 microglobulin and albumin; and with "genetic factors using molecular fluorescence".
      To treat: radiation, chemotherapy (also with autologous stem cell transplantation.

  4. I'm kind of curious as to why you chose to write about this article? It is of course a review article written for an audience of myeloma researchers, so it isn't that surprising that someone new to myeloma research would find it rather challenging. However, I think that it does exactly what it is designed to do: provide an overview of the current state of knowledge of this dangerous disease.

    1. Well, I used to have a co-worker who developed MM when I was living in San Antonio so when I saw the title I thought it would be a good idea to learn about it. I'd have to agree that I found it challenging, I almost changed my article to something else but I decided to pull through. I understand the article met it's purpose, maybe I'm just used to articles that focus on one thing at a time?

  5. Does the article say why melphalan has proven to be effective against the drug resistance?
