The idea to
specifically study this group of patients was based
on groundbreaking research Garon published in the New England Journal of Medicine last year, which found that among patients who received pembrolizumab, those with PD - L1 expression
on at least 50 percent of their
cancer cells showed the longest survival and disease control.
The hope is that 3BP
specifically kills certain
cancer cells — while leaving normal
cells alone — because they rely more
on glucose metabolism than
on an alternative pathway called oxidative phosphorylation.
Figure
on the left: Analyzing the relative sensitivity of hundreds of
cancer cell lines to commonly used anti-
cancer drugs (each dot) reveals that
cells with suppressed expression of one proteasome cap subunit are
specifically resistant to treatments with the proteasome inhibitors MG132 and bortezomib.
Previous studies of genetic alterations in lymphoma and lung
cancer have found that certain genetic mutations —
specifically when part of a gene breaks off and gets fused to another — can inappropriately switch
on ALK, driving
cancer cells to grow and divide.
In the context of the current study, the researchers have developed a pre-clinical model system that
specifically captures the impact of a treatment
on cancer stem
cells.
Research
on metastatic colorectal
cancer and sarcoma, however, suggests a potential benefit from adding local therapy — treatment directed
specifically at the tumor
cells — to the standard approach of systemic therapy.
When Kaufman, Zon and colleagues looked to see what was different about these early
cancer cells, they found that crestin and the other activated genes are the same ones turned
on during zebrafish embryonic development —
specifically, in the stem
cells that give rise to the pigment
cells known as melanocytes, within a structure called the neural crest.
«With further research we hope to create a nontoxic nanocarrier that could provide targeted delivery of the TM - 025 and TM - 026 analogs
specifically to
cancer cells,» said Gitali Indra, an OSU assistant professor and also a lead and corresponding author
on the study.
One of the immunotherapeutic approaches that has been explored thus far relies
on the use of monoclonal antibodies that
specifically target a protein present
on the surface of prostate
cancer cells called prostate specific membrane antigen (PSMA) to elicit an anti-tumor immune response and control the
cancer.
Once taken up by antigen - presenting
cells, which help focus the immune system
on an invader, the vaccine releases a factor that heightens their attention
specifically to the
cancer - promoting protein E7, a so - called oncoprotein that not only enables the human papillomavirus to multiply, but potentially cervical
cancer cells to do the same.
