PJ34, a stroke therapy, is seen to offer ‘great potential’ for causing the aggressive tumor, as well as others, to self-destruct in humans, Tel Aviv University researchers say By Shoshanna … In addition to the measured moderate change in PANC1 tumors’ size in one mouse (mouse # 19) the tumor started to shrink after 3 weeks of daily treatments with PJ34 and disappeared on day 56 of the TAU study published on October 22, 2019. The molecule PJ34 now is being tested in pre-clinical trials according to FDA regulations before larger animal trials and then human clinical trials can begin. PJ34, which is permeable in the cell membrane, accessed and eradicated human PDAC cells in xenografts without impairing normal proliferating cells infiltrated into the tumors. Recent reports demonstrate an exclusive eradication of a variety of human cancer cells by the modified phenanthridine PJ34. As trials progress, recurrence will need to be investigated further to help researchers plan length of treatment and evaluate how effective it is. This is a limited, but important finding, since pancreatic cancer, is currently resistant to all treatments, and patients have poor chances of surviving for 5 years after being diagnosed. While further research needs to be done in order to calculate the appropriate doses that would have to be administered to human … Unlike other PARP inhibitors (such as 3-AB), PJ34 … PJ34 works by interfering with the process in which cancer cells divide. Thus, eradication of human PANC1 cells in the xenografts is deduced from the reduction in the measured (with a high statistical significance) immuno-labeling of three arbitrarily selected human proteins in PANC1 tumors developed in mice treated with PJ34, compared to their immunolabeling in tumors of untreated mice. Therefore trials like this almost always have to take place in mice or a similar animal to ensure the treatment is safe for human testing. In collaboration with Dr. Talia Golan’s team at the Cancer Research Center at Sheba Medical Center, the scientists injected PJ34 into the mice for 14 days in a row. The work was funded by an ICRF grant and a donation of American Friends of Tel Aviv University.

This molecule causes an anomaly during the … They found that there were 80-90% less cancer cells in most of the mice than before PJ34. This study is in the second stage: preclinical trials. This research team did not specifically study whether or not the treatment could prolong the lifespan of a pancreatic cancer patient. The phenanthrenes PJ34, Phen and Tiq-A, the researchers found, modify kinesins (HSET/kifC1 and kif18A) and NuMA (nuclear mitotic apparatus protein) in a variety of human cancer cells. The most … 07272699. This is the layer of cells that surrounds the tumour. Eradication of PANC1 cells in the tumors is also in line with PJ34-evoked cell death of PANC1 cells. How PJ34 interacts with the stroma and if it can effectively move through it to reach cancerous cells will be a key question to answer if it is to become a viable treatment. The research was conducted with xenografts -- transplantations of human pancreatic cancer into immunocompromised mice. The research team, led by Dr Talia Golan and Professor Cohen-Armon, are optimistic that clinical trials could take place in as little as two years depending on funding. Figure 1. Thus, the exclusive eradication of PANC1 cells in the xenografts could be screened by un-affected cells in the stroma, causing a discrepancy between the modest reduction in the volume of PANC1 tumors developed in PJ34 treated mice versus the substantial reduction of PANC1 cells in these tumors. Pancreatic cancer accounts for about 3 percent of all cancers in the US and about 7 percent of all cancer deaths, says the American Cancer Society (ACS). About 45,750 people (23,800 men and 21,950 women) will die of pancreatic cancer.

We conducted the first prospective clinical trial of molecular profiling to … This causes cells to die during division, stopping the growth of the tumour and shrinking it at the same time. An abundantly expressed protein in fibroblasts infiltrated in the PANC1 tumors was not affected in mice treated with PJ34. When this molecule was injected into mice it caused pancreatic cancer cells to stop multiplying and die. This causes … PJ34 now is being tested in pre-clinical trials according to FDA regulations before larger animal trials and then human clinical trials can begin. Its estimates for pancreatic cancer in the USA for 2019 are: Furthermore, this TAU study reported 30 days after the treatment with PJ34 had been terminated, an 80–90 percent reduction in human proteins in the tumors had been measured. Mice that were treated daily with PJ34 had a reduction in the size of their tumours and in one mouse, the tumour completely disappeared. PJ34 is being tested in pre-clinical trials according to FDA regulations before clinical trials on larger animals and then humans begin, Tel Aviv University said in a statement. Their small quantities are attributed to the eradication of the human PANC1 cancer cells, the only human cells in the xenografts. About 56,770 people (29,940 men and 26,830 women) will be diagnosed with pancreatic cancer. In pancreatic cancer, these cells begin as non-cancerous but may eventually promote the growth of the tumour and prevent treatments from working. In support, MTD (maximal tolerance dose) experiment performed with immunocompetent BALB/C mice IV injected with higher doses of PJ34 did not exert morbidity or mortality, nor indicated any abnormal clinical signs in the mice or their weight gain. However, as this research was carried out in mice, it is still a long way from being a licensed treatment for pancreatic cancer. In a research study hosted by Tel Aviv University, mice with human pancreatic cancer cells were injected with a molecule called PJ34 for two weeks, and within one month, there was a 90% … PJ34 works by interfering with the process in which cancer cells divide.
