LPA Receptor Promotes Progesterone Receptor Phosphorylation through PKCα in Human Glioblastoma Cells.

Cells 2021 Apr 4;10(4). Epub 2021 Apr 4.

Departamento de Medicina Genómica y Toxicología Ambiental, Instituto de Investigaciones Biomédicas, Universidad Nacional Autónoma de México (UNAM), 04510 Ciudad de México, Mexico.

Lysophosphatidic acid (LPA) induces a wide range of cellular processes and its signaling is increased in several cancers including glioblastoma (GBM), a high-grade astrocytoma, which is the most common malignant brain tumor. LPA receptor is expressed in GBM cells and its signaling pathways activate protein kinases C (PKCs). A downstream target of PKC, involved in GBM progression, is the intracellular progesterone receptor (PR), which can be phosphorylated by this enzyme, increasing its transcriptional activity.

Rho GTPases in Retinal Vascular Diseases.

Int J Mol Sci 2021 Apr 1;22(7). Epub 2021 Apr 1.

Department of Ophthalmology, Osaka University Graduate School of Medicine, Osaka 563-0871, Japan.

The Rho family of small GTPases (Rho GTPases) act as molecular switches that transduce extrinsic stimuli into cytoskeletal rearrangements. In vascular endothelial cells (ECs), Cdc42, Rac1, and RhoA control cell migration and cell-cell junctions downstream of angiogenic and inflammatory cytokines, thereby regulating vascular formation and permeability. While these Rho GTPases are broadly expressed in various types of cells, RhoJ is enriched in angiogenic ECs. Read More

The Roles of HIF-1α in Radiosensitivity and Radiation-Induced Bystander Effects Under Hypoxia.

Front Cell Dev Biol 2021 25;9:637454. Epub 2021 Mar 25.

Patrick G Johnston Centre for Cancer Research, Queen's University Belfast, Belfast, United Kingdom.

Radiation-induced bystander effects (RIBE) may have potential implications for radiotherapy, yet the radiobiological impact and underlying mechanisms in hypoxic tumor cells remain to be determined. Using two human tumor cell lines, hepatoma HepG2 cells and glioblastoma T98G cells, the present study found that under both normoxic and hypoxic conditions, increased micronucleus formation and decreased cell survival were observed in non-irradiated bystander cells which had been co-cultured with X-irradiated cells or treated with conditioned-medium harvested from X-irradiated cells. Although the radiosensitivity of hypoxic tumor cells was lower than that of aerobic cells, the yield of micronucleus induced in bystander cells under hypoxia was similar to that measured under normoxia indicating that RIBE is a more significant factor in overall radiation damage of hypoxic cells.

Hypoxia-Inducible Factor-2α as a Novel Target in Renal Cell Carcinoma.

J Kidney Cancer VHL 2021 7;8(2):1-7. Epub 2021 Apr 7.

George Washington University Hospital, School of Medicine and Health Sciences, George Washington University, Washington, DC, USA.

Hypoxia-inducible factor (HIF), an important mediator of hypoxia response, is implicated in tumorigenesis in the setting of pseudohypoxia, such as in the inactivation of von Hippel-Lindau tumor suppressor protein (pVHL), leading to development and progression of clear cell renal cell carcinoma (ccRCC). Targeting downstream molecules in HIF pathway, such as vascular endothelial growth factor (VEGF), has led to improvement in clinical outcome for patients with advanced ccRCC, but such therapy thus far has been limited by eventual resistance and treatment failure. Following the discovery of HIF-2α playing a key role in ccRCC carcinogenesis, inhibitors targeting HIF-2α have been developed and have demonstrated encouraging efficacy and safety profile in clinical trials.

Targeting HIF-α for robust prevascularization of human cardiac organoids.

J Tissue Eng Regen Med 2021 Feb 8;15(2):189-202. Epub 2020 Dec 8.

Bioengineering Department, Clemson University, Clemson, SC 29634, USA.

Prevascularized 3D microtissues have been shown to be an effective cell delivery vehicle for cardiac repair. To this end, our lab has explored the development of self-organizing, prevascularized human cardiac organoids by co-seeding human cardiomyocytes with cardiac fibroblasts, endothelial cells, and stromal cells into agarose microwells. We hypothesized that this prevascularization process is facilitated by the endogenous upregulation of hypoxia-inducible factor (HIF) pathway in the avascular 3D microtissues. Read More

National Health Commission Key Laboratory of Radiobiology, School of Public Health, Jilin University, Changchun, Jilin 130000, P.R. China.

Radiotherapy is widely used in the management of lung cancer, and physicians are aware that the effect of radiotherapy is dependent on radiosensitivity. Although a series of blockers and activators targeting molecules related to radioresistance have been developed as radiation sensitizers, compensatory mechanisms or drug resistance limits their clinical efficacy. The identification of a key molecule related to lung cancer cell radioresistance or an effective molecular target is a challenging but important problem in radiation oncology. Read More
