Vitamin B Derivative (Nicotinamide)Appears to Reduce Skin Cancer Risk.

Vitamin B Derivative (Nicotinamide)Appears to Reduce Skin Cancer Risk. Skin Therapy Lett. 2017 Sep;22(5):1-4 Authors: Nazarali S, Kuzel P Abstract Nicotinamide, an amide form of vitamin B3, has shown the potential to treat a variety of dermatological conditions, including acne, rosacea, and atopic dermatitis. Recent studies have demonstrated the role of nicotinamide, in both topical and oral forms, as a chemopreventive agent against skin cancer. Its anti-carcinogenic role may be due to its ability to enhance DNA repair and prevent ultraviolet (UV)-induced immunosuppression, which is known to contribute to the progression of pre-malignant lesions. Furthermore, nicotinamide is a precursor of essential coenzymes for many important reactions in the body, including the production of nicotinamide adenine dinucleotide (NAD). NAD is a key coenzyme in the synthesis of adenosine triphosphate (ATP), which transports chemical energy within cells. Therefore, nicotinamide plays a significant role in supporting energy-dependent cellular processes, including DNA repair. PMID: 28888216 [PubMed - in process]

Kothapalli, J. Thomas BrennaAbstractBranched chain fatty acids (BCFA) and linear chain/normal odd chain fatty acids (n-OCFA) are major fatty acids in human skin lipids, especially sebaceous gland (SG) wax esters. Skin lipids contain variable amounts of monounsaturated BCFA and n-OCFA, in some reports exceeding over 20% of total fatty acids. Fatty acid desaturase 2 (FADS2) codes for a multifunctional enzyme that catalyz...

This study evaluated outcomes associated with treatment strategies for this nonagenarian population.MethodsTreatment and overall survival for patients 90 years and older with NSCLC in the National Cancer Data Base (2004-2014) were evaluated using logistic regression, the Kaplan-Meier method, and multivariable Cox proportional hazard models.ResultsThe majority (n = 4152, 57.6%) of the 7205 patients 90 years or older with stage I-IV NSCLC did not receive any therapy. For the entire cohort, receiving treatment was associated with significantly better survival when compared with no therapy (5-year survival, 9.3% [95% confidenc...

Multisubunit RNAPs carry out transcription and are represented, without exception, in all cellular life forms as well as in nucleo-cytoplasmic DNA viruses. Since their discovery, multisubunit RNAPs have been the focus of intense structural and functional studies revealing that they all share a well-conserved active-site region c...

In conclusion, data presented in the current study suggest that tobacco smoking might cause alveolar tissue inflammation and vascular injury causing an immune response that elevates the white blood cells count. Another suggestion is that tobacco smoking defects the pulmonary gaseous exchange mechanism leading to the secondary polycythemia indicated by the increase in red blood cell count, hemoglobin levels, hematocrit and by the low serum erythropoietin levels.

In this study, we report that the dietary isoflavone genistein (GN) synergistically improved antineoplasticity of CC in breast cancer by arresting cells at G2/M phase culminating in ROS dependent apoptosis. The combination of CC plus GN caused dysregulation of Bax and Bcl-2 ratio inducing mitochondrial dysfunction, activation of Caspase-3/7, -9 and PARP cleavage. Further, combination significantly suppresses phosphorylation of PI3K/Akt/NF-κB, enhancing apoptosis. Additionally, combination markedly reduced tumor growth compared to CC and GN alone in mouse 4T1 breast tumor model.SignificanceTogether, these studies sugg...

Most studies of the effect of vitamin D status on outcomes do not account for individual-level SES. The ability to adjust for SES in epidemiologic studies, when data on conventional SES measures have not been obtained, would be advantageous. We identified all s...
