Exogenous sex hormones, menstrual and reproductive history, and risk of non-melanoma skin cancer among women: a systematic literature review and meta-analysis.

Sci Rep 2021 Apr 19;11(1):8524. Epub 2021 Apr 19.

Department of Experimental Oncology, European Institute of Oncology (IEO), IRCCS, Milan, Italy.

Non-melanoma skin cancers (NMSC) are more frequent among men, but women (especially those aged < 40 years) have experienced steeper growth in their incidence rates in recent years. Hormonal factors were hypothesized to be playing a role in modulating NMSC risk, but the studies published to date provided conflicting results. We systematically reviewed and meta-analysed the studies focusing on the association between hormone-related characteristics (use of exogenous sex hormones, and aspects of menstrual and reproductive history) and the risk of NMSC among women.

Age and insulin-like growth factor-1 impact PCNA mono-ubiquitination in UVB-irradiated human skin.

J Biol Chem 2021 Mar 19:100570. Epub 2021 Mar 19.

Departments of Pharmacology and Toxicology. Electronic address:

Non-melanoma skin cancers occur primarily in individuals over the age of 60 and are characterized by an abundance of ultraviolet (UV) signature mutations in keratinocyte DNA. Though geriatric skin removes UV photoproducts from DNA less efficiently than young adult skin, it is not known whether the utilization of other pro-survival but potentially mutagenic DNA damage tolerance systems such as translesion synthesis (TLS) is altered in older individuals. Using mono-ubiquitination of the replicative DNA polymerase clamp protein PCNA (proliferating cell nuclear antigen) as a biochemical marker of TLS pathway activation, we find that UVB exposure of skin from individuals over the age of 65 results in a higher level of PCNA mono-ubiquitination than in the skin of young adults.

Sunscreens and their usefulness: have we made any progress in the last two decades?

Nick Serpone

Photochem Photobiol Sci 2021 Feb 18;20(2):189-244. Epub 2021 Feb 18.

Dipartimento di Chimica, Universita degli Studi di Pavia, Via Taramelli 12, Pavia, 27100, QC, Italy.

Sunscreens have now been around for decades to mitigate the Sun's damaging ultraviolet (UV) radiation which, although essential for the existence of life, is a recognized prime carcinogen. Accordingly, have suncreams achieved their intended purposes towards protection against sunburns, skin photo-ageing and the like? Most importantly, however, have they provided the expected protection against skin cancers that current sunscreen products claim to do? In the last two decades, there have been tens, if not hundreds of studies on sunscreens with respect to skin protection against UVB (280‒320 nm)-traditionally sunscreens with rather low sun protection factors (SPF) were intended to protect against this type of radiation-and UVA (320‒400 nm) radiation; a distinction between SPF and UVA protection factor (UVA-PF) is made. Many of the studies of the last two decades have focused on protection against the more skin-penetrating UVA radiation. Read More
