Livin promotes colon cancer progression by regulation of H2A.XY39ph via JMJD6

Publication date: Available online 22 August 2019Source: Life SciencesAuthor(s): Yang Ge, Bao-lin Liu, Jun-peng Cui, Shu-qiang LiAbstractLivin is an important member of the human inhibitor of apoptosis proteins (IAPs) family. IAPs are proteins with antiapoptotic abilities, and their functions are different from the Bcl-2 (B-cell lymphoma-2) family proteins. However, the precise role of Livin in colon cancer progression remains unclear. The purpose of this study is to assess the effect of overexpression Livin in colon cancer cells and to examine its molecular mechanism. We demonstrated that Livin induced a colon cancer phenotype, including proliferation and migration, by regulating H2A.XY39ph (histone family 2A variant (H2AX) phosphorylated on the 39th serine site). We elucidated that Livin degraded Jumonji-C domain-containing 6 protein (JMJD6), which was mediated by the proteasome murine double minute 2 (MDM2), thereby regulating H2A.XY39ph. Above all, the overexpression of JMJD6 recovered H2A.XY39ph in colon cancer cells with a high level of Livin, thus inhibiting colon cancer malignancy progression. These results reveal a previously unrecognized role for Livin in regulating the tumor-initiating capacity in colon cancer and provide a novel treatment strategy in cancer via the interruption of H2A.XY39ph function and the interaction between H2A.XY39ph and JMJD6.

BACKGROUND: Primary colorectal lymphoma is rare, representing 0.2% to 0.6% of all colorectal cancers. Because of its low incidence and histologic variety, no treatment guidelines exist. OBJECTIVE: The purpose was to report the experience of primary colorectal lymphoma in an institutional and a national cohort. DESIGN: This was a retrospective cohort study. SETTINGS: The study was conducted with institutional data composed of 3 tertiary referral centers and national data. PATIENTS: Patients with primary colorectal lymphoma were identified within the Mayo Clinic (1990–2016) and the Surveillance, Epidemiol...

In conclusion, a case of synchronous existence of colon cancer, DLBCL, and MDS is reported, which suggests that careful attention should be paid clinically to checking the state of bone marrow for elderly cancer patients. Efforts are also needed to establish an effective system for distinguishing the origin of multi-existent cancers and to develop effective therapeutic regimens for multi-existent cancers with fewer side effects.

Discussion: The incidence of solid cancer in this cohort of patients with FL was low and not greater than in the general population. However, the risk may be greater in female patients treated with bendamustine. PMID: 31368395 [PubMed - as supplied by publisher]

President Donald Trump on Monday signed legislation that will extend the September 11th Victim Compensation Fund until 2092. During the signing ceremony at the White House, Trump was surrounding by first responders, survivors and family members of several who died in the 2001 terrorist attack on the United States. The U.S. House of Representatives and the U.S Senate voted overwhelmingly last week to approve the legislation that will provide a lifetime of assistance for victims and their families. The extension will allow the fund, first established in 2001, to pay for past and future medical claims of those effected by the...

Abstract Actinomycosis can mask malignant diseases. This paper reports a case of colonic diffuse large B-cell lymphoma (DLBCL), which was misdiagnosed as abdominal actinomycosis. A 76-year-old woman presented with right flank pain and weight loss. Abdominal CT and colonoscopy revealed a huge ascending colon mass. Despite the initial impression of a malignancy, a colonoscopic biopsy revealed no malignant cells, but sulfur granules and a filamentous organism suggesting actinomycosis. Intravenous penicillin G was administered under the impression of abdominal actinomycosis but her condition deteriorated rapidly. Foll...

The U.S. Senate followed the House of Representatives on Tuesday and passed legislation that will extend the September 11 Victim Compensation Fund until 2092. The legislation will fund all current and future medical claims of those effected by the 9/11 terrorist attacks on the World Trade Center in New York City, the Pentagon in Washington, and United Flight 93, which crashed in Shanksville, Pennsylvania. The extension of funding will benefit victims who may develop mesothelioma linked to the more than 400 tons of asbestos that covered the 16-acre disaster zone after the twin towers fell. According to World Trade Center R...

The Senate gallery erupted in applause from politicians and first responders on Tuesday after a 97-2 vote to extend the September 11 Victim Compensation Fund until 2092. The reauthorization will fund all current and future medical claims of those effected by the 9/11 terrorist attacks on the World Trade Center in New York City, the Pentagon in Washington, and United Flight 93, which crashed in Shanksville, Pennsylvania. The extension will allow victims and their families to file claims through 2090, but they will be paid out through 2092. The extension of funding will benefit victims who may develop mesothelioma linked to ...

ConclusionsDue to a large placebo response, we were unable to determine if a drug effect was present. However, we did observe substantial improvement in self-reported cognitive symptoms, likely resulting from factors related to participation in the trial rather than specific drug treatment effects.Trial registrationThe study was registered withclinicaltrials.gov (trial registration: NCT02312943).Implications for Cancer SurvivorsThese results suggest that women with pCRCI can exhibit improvement in subjective cognition, with attention paid to symptoms and close follow-up over a short period of time.

(Northwestern University) Many of the deadliest or most common cancers get the least amount of nonprofit research funding, reports a new Northwestern Medicine study. 'Embarrassing' or stigmatized cancers, like lung and liver, are underfunded. Colon, endometrial, liver and bile duct, cervical, ovarian, pancreatic and lung cancers were all poorly funded compared to how common they are and how many deaths they cause, the study found. In contrast, breast cancer, leukemia, lymphoma and pediatric cancers were all well-funded, respective to their impact on society.
