Department of Dermatology, Perelman School of Medicine at the University of Pennsylvania, Philadelphia, PA.

Background: BRAF inhibition has improved overall survival in patients with BRAF mutant melanoma but this is associated with a range of known and predictable cutaneous side effects, including squamous cell carcinomas associated with RAS mutations.

Methods: We identified three severely dysplastic nevi, one atypical intraepidermal melanocytic proliferation, and four melanoma in situ lesions, newly arising in four patients undergoing treatment with vemurafenib. To characterize mutations in these atypical melanocytic lesions, we used a custom iPlex panel detecting 74 mutations in 13 genes known to play a role in melanoma pathogenesis. Read More

BRD4 interacts with PML/RARα in acute promyelocytic leukemia.

Front Med 2018 Dec 14;12(6):726-734. Epub 2018 Dec 14.

State Key Laboratory of Medical Genomics, Ruijin Hospital Affiliated to Shanghai Jiao Tong University School of Medicine, Shanghai, 200025, China.

Bromodomain-containing 4 (BRD4) has been considered as an important requirement for disease maintenance and an attractive therapeutic target for cancer therapy. This protein can be targeted by JQ1, a selective small-molecule inhibitor. However, few studies have investigated whether BRD4 influenced acute promyelocytic leukemia (APL), and whether BRD4 had interaction with promyelocytic leukemia-retinoic acid receptor α (PML/RARα) fusion protein to some extent.

Cell-Based Model of the Generation and Maintenance of the Shape and Structure of the Multilayered Shoot Apical Meristem of Arabidopsis thaliana.

Bull Math Biol 2018 Dec 14. Epub 2018 Dec 14.

Department of Mathematics, University of California, Riverside, USA.

One of the central problems in animal and plant developmental biology is deciphering how chemical and mechanical signals interact within a tissue to produce organs of defined size, shape, and function. Cell walls in plants impose a unique constraint on cell expansion since cells are under turgor pressure and do not move relative to one another. Cell wall extensibility and constantly changing distribution of stress on the wall are mechanical properties that vary between individual cells and contribute to rates of expansion and orientation of cell division.

Role of a cotton endoreduplication-related gene, GaTOP6B, in response to drought stress.

Planta 2018 Dec 14. Epub 2018 Dec 14.

Zhengzhou Research Base, State Key Laboratory of Cotton Biology, Zhengzhou University, Zhengzhou, 450001, Henan, People's Republic of China.

Main Conclusion: Cotton GaTOP6B is involved in cellular endoreduplication and a positive response to drought stress via promoting plant leaf and root growth. Drought is deemed as one of adverse conditions that could cause substantial reductions in crop yields worldwide. Since cotton exhibits a moderate-tolerant phenotype under water-deficit conditions, the plant could therefore be used to characterize potential new genes regulating drought tolerance in crop plants.
