Important molecule in ovarian cancer

An important new target for ovarian cancer therapy has been identified by scientists. Contrary to current research, this new study found that LKB1 is an important molecule in the cancer's promotion and survival. Their research definitively shows that ovarian cancer cells still have LKB1 and that this molecule allows ovarian cancer spheroids to change their metabolism, promote tumor cell survival and make them more resistant to chemotherapy.

The National Cancer Institute in Rockville, Maryland, has opened an innovative clinical trial for patients with peritoneal mesothelioma that will explore the safety and effectiveness of a novel CAR T-cell therapy. The phase I trial also is being conducted at Washington University in St. Louis. It is aimed at patients whose disease has relapsed after initial chemotherapy treatment. It involves a laboratory modification of a patient’s T cells — a type of white blood cell — that can help the immune system kill the cancer. CAR T-cell therapy is a form of gene therapy that has been highly successful with blood...

However, the chemotherapy benefits are eventually limited due to drug toxicity to normal tissues and cells, which cause several and harsh side effects. Paclitaxel (PCX) is the ...

Abstract BMI-1 (B-lymphoma Mo-MLV insertion region 1) is a key protein partner in polycomb repressive complex 1 (PRC1) that helps in maintaining the integrity of the complex. It is also a key player in ubiquitination of histone H2A which affects gene expression pattern involved in various cellular processes such as cell proliferation, growth, DNA repair, apoptosis and senescence. In many cancers, Overexpression of BMI1correlates with advanced stages of disease, aggressive clinicopathological behavior, poor prognosis resistance to radiation and chemotherapy. BMI1 is emerging as a key player in EMT, chemo-resistance...

Publication date: August 2018Source: Seminars in Cancer Biology, Volume 51Author(s): Yanina Natanzon, Ellen L. Goode, Julie M. CunninghamAbstractOvarian cancer is a disease with a poor prognosis and little progress has been made to improve treatment. It is now recognized that there are several histotypes of ovarian cancer, each with distinct epidemiologic and genomic characteristics. Cancer therapy is moving beyond classical chemotherapy to include epigenetic approaches. Epigenetics is the dynamic regulation of gene expression by DNA methylation and histone post translational modification in response to environmental cues....

Abstract Cancer patients' quality of life is greatly dependent on the efficacy of treatments and their associated side effects, which can significantly reduce the overall quality of life. Although the effectiveness of cancer treatments has improved over time, adverse effects persist with each treatment. Some side effects, such as paclitaxel-induced peripheral neuropathy, can be dose limiting, thus further reducing the potential of paclitaxel chemotherapy treatment. Premature ovarian failure in young female patients due to radiation and chemotherapy therapy can have devastating infertility consequences. In rec...

Authors: Zhang C, Wang M, Shi C, Shi F, Pei C Abstract Chemotherapy is one of the main treatments for ovarian cancer (OC). Cisplatin combined with paclitaxel is a commonly used chemotherapy regimen. However, effective cancer therapy is hindered by a patient's resistance to cisplatin. The mechanism that potentially leads to that resistance is unclear. The current study examined the mechanism by which Linc00312 is involved in resistance to cisplatin in OC. Quantitative real-time PCR (RT-qPCR) was used to test for expression of Linc00312 in freshly frozen tissue samples of OC and in SKOV3 and SKOV3/DDP cells. In situ ...

ConclusionsDecreased splicing efficiency and global intron retention is a novel stress response mechanism that may promote survival of malignant cells following therapy. We found that this mechanism can be inhibited by pladienolide B, which significantly increases the sensitivity of cancer cells to cisplatin which makes it a good candidate drug for improving the efficiency of cancer therapy.

Anti-cancer therapy, particularly chemotherapy, damages ovarian follicles and promotes ovarian failure. The only pharmacological means for protecting the ovaries from chemotherapy-induced injury is gonadotrophin-releasing hormone agonist, but its efficiency remains controversial; ovarian transposition is used to shield the ovary from radiation when indicated. Until the late 1990s, the only option for fertility preservation and restoration in women with cancer was embryo cryopreservation. The development of other assisted reproductive technologies such as mature oocyte cryopreservation and in vitro maturation of oocytes has...

Authors: Hulin-Curtis SL, Davies JA, Jones R, Hudson E, Hanna L, Chester JD, Parker AL Abstract Ovarian cancer is often termed a silent killer due to the late onset of symptoms. Whilst patients initially respond to chemotherapy, they rapidly develop chemo-resistance. Oncolytic adenoviruses (OAds) are promising anti-cancer agents engineered to "hijack" the unique molecular machinery of cancer cells enabling tumour-selective viral replication. This allows spread to adjacent cells and amplification of oncolysis within the tumour. OAds represent an excellent opportunity for ovarian cancer therapy via intra-pe...

Scientists at the Vaccine and Immunotherapy Center (VIC) at Massachusetts General Hospital have uncovered a novel, two-agent immunotherapy combination that worked surprisingly well in animal models with malignant mesothelioma. The discovery has sparked new optimism for immunotherapy, which has struggled to provide consistently positive results with aggressive cancers such as mesothelioma. “This is the beginning of a new story of hope, a new combination of immunotherapy,” Dr. Mark Poznansky, director of the VIC and associate professor at Harvard Medical School, told Asbestos.com. “It worked quite well in a...
