Medical News Today: Does HIV increase cancer risk?

HIV can weaken a person ’s immune system, which can increase the risk of certain types of cancer. Such cancers include Kaposi’s sarcoma, non-Hodgkin lymphoma, and cervical, lung, anal, and oral cancer. However, effective treatment can significantly reduce the risk of developing these cancers.

Publication date: Available online 23 October 2019Source: Molecular and Cellular ProbesAuthor(s): Yi ChenAbstractCyclooxygenase-2 (COX-2) is an inducible enzyme that plays a key role in the inflammatory cascade through the generation of prostaglandins. Recent studies have found that COX-2 is closely related to the occurrence and development of tumors, angiogenesis and metastasis of tumors. Overexpressed COX-2 has become a predictive biomarker for progression of pre-malignant towards cancer in some tissues, which makes the detection of COX-2 of great value and clinical significance. This review highlights COX-2-specific flu...

The synthesis of AuNPs was optimized by varying CMXG amount, gold ion concentration, and MWI time. The CMXG@AuNPs exhibited a spherical shape, high crystallinity, and narrow size distribution (i.e. 8-10 nm). The electrostatic interaction-mediated ...

In this study, a series of deletion mutants or point mutants of horPDPN were produced for analyzing the PMab-219 epitope using flow cytometry. The analysis of deletion mutants showed that N-terminus of PMab-219 epitope exists between 55th amino acid (aa) and 60th aa of horPDPN. Furthermore, the analysis of point mutants demonstrated that the critical epitope of PMab-219, which was developed by CBIS method, could include Val59, Arg61, Ser62, and Thr63 of horPDPN, indicating that PMab-219 epitope is independent of PLAG domain or PLD of horPDPN.

Angelastro, Gino A. CortopassiAbstractAMP-activated protein kinase (AMPK) is a eukaryotic energy sensor and protector from mitochondrial/energetic stress that is also a therapeutic target for cancer and metabolic disease. Metformin is an AMPK inducer that has been used in cancer therapeutic trials. Through screening we isolated cetylpyridinium chloride (CPC), a drug known to dose-dependently inhibit mitochondrial complex 1, as a potent and dos...

Bourbon, Liuliang Qin, Kevin Zhao, Taiyang Ye, Dezheng Zhao, Huiyan ZengAbstractPathological angiogenesis is a hallmark of many diseases. Previously, we reported that orphan nuclear receptor TR3/Nur77 was a critical mediator of angiogenesis to regulate tumor growth, sepsis and skin wound healing. However, none of the TR3/Nur77 targeting molecule has been in clinical trial so far. Here, we designed and generated novel TR3 shRNAs and two minigenes that had therapeutic potential for cancer trea...

Publication date: Available online 23 October 2019Source: Genes &DiseasesAuthor(s): Andrew N. Lane, Richard M. Higashi, Teresa W-M. FanAbstractThe genetic alterations associated with cell transformation are in large measure expressed in the metabolic phenotype as cancer cells proliferate and change their local environment, and prepare for metastasis. Qualitatively, the fundamental biochemistry of cancer cells is generally the same as in the untransformed cells, but the cancer cells produce a local environment, the TME, that is hostile to the stromal cells, and compete for nutrients. In order to proliferate, cells need ...

Methods performing this task have been extensively evaluated on synthetic, and to a lesser extent real data sets. In contrast to these test evaluations, applications to gene expression data of human cancers are often limited by fewer samples and more potential regula...

Abstract: We utilized computerized record-linkage methods to link HIV and cancer databases with limited unique identifiers in Pune, India, to determine feasibility of linkage and obtain preliminary estimates of cancer risk in persons living with HIV (PLHIV) as compared with the general population. Records of 32,575 PLHIV were linked to 31,754 Pune Cancer Registry records (1996–2008) using a probabilistic-matching algorithm. Cancer risk was estimated by calculating standardized incidence ratios (SIRs) in the early (4–27 months after HIV registration), late (28–60 months), and overall (4–60 months) i...
