In this recent study, DNA data from 900 patients with colorectal cancer were reviewed. Analysis of the data showed a distinct mutation signature, a pattern that had never been identified before but indicated a type of DNA damage called "alkylation." Red meat contains chemicals that can cause alkylation. High levels of tumor alkylation damage are seen only in patients who consume an average of more than 150 grams of meat per day, roughly equivalent to two or more meals. On the other hand, a group of researchers in 2019 in a controversial conclusion stated that they do not have much confidence in reducing deaths from colon cancer by avoiding red meat.

Normal Tissue Toxicity

Cancer is one of the most complicated diseases in present-day medical science. Yearly, several studies suggest various strategies for preventing carcinogenesis. Furthermore, experiments for the treatment of cancer with low side effects are ongoing. Chemotherapy, targeted therapy, radiotherapy and immunotherapy are the most common non-invasive strategies for cancer treatment. One of the most challenging issues encountered with these modalities is low effectiveness, as well as normal tissue toxicity for chemo-radiation therapy. The use of some agents as adjuvants has been suggested to improve tumor responses and also alleviate normal tissue toxicity. Resveratrol, a natural flavonoid, has attracted a lot of attention for the management of both tumor and normal tissue responses to various modalities of cancer therapy. As an antioxidant and anti-inflammatory agent, in vitro and in vivo studies show that it is able to mitigate chemo-radiation toxicity in normal tissues. However, clinical studies to confirm the usage of resveratrol as a chemo-radioprotector are lacking. In addition, it can sensitize various types of cancer cells to both chemotherapy drugs and radiation. In recent years, some clinical studies suggested that resveratrol may have an effect on inducing cancer cell killing. Yet, clinical translation of resveratrol has not yielded desirable results for the combination of resveratrol with radiotherapy, targeted therapy or immunotherapy. In this paper, we review the potential role of resveratrol for preserving normal tissues and sensitization of cancer cells in combination with different cancer treatment modalities.

Background: Although conventional chemotherapy is the most common method for cancer treatment, it has several side effects such as neuropathy, alopecia and cardiotoxicity. Since the drugs are given to body systemically, normal cells are also affected, just like cancer cells. However, in recent years, targeted drug delivery has been developed to overcome these drawbacks. Objective: The aim of this study was targeted co-delivery of doxorubicin (Dox) which is an anticancer agent and D-α-Tocopherol polyethylene glycol 1000 succinate (vitamin E TPGS or simply TPGS) to breast cancer cells. For this purpose, Magnetic Nanoparticles (MNPs) were synthesized and coated with Oleic Acid (OA). Coated nanoparticles were encapsulated in Poly Lactic-co-Glycolic Acid (PLGA) and TPGS polymers and loaded with Dox. The Nanoparticles (NPs) were characterized by Fourier Transform Infrared (FTIR) spectroscopy, zetapotential analysis, Dynamic Light Scattering (DLS) analysis, Thermal Gravimetric Analysis (TGA) and Scanning Electron Microscope (SEM) analysis. Results: The results showed that NPs were spherical, superparamagnetic and in the desired range for use in drug targeting. The targetability of NPs was confirmed. Moreover, TPGS and Dox loading was shown by TGA and FTIR analyses. NPs were internalized by cells and the cytotoxic effect of drug loaded NPs on sensitive (MCF-7) and drug-resistant (MCF-7/Dox) cells were examined. It was seen that the presence of TPGS increased cytotoxicity significantly. TPGS also enhanced drug loading efficiency, release rate, cellular internalization. In MCF- 7/Dox cells, the drug resistance seems to be decreased when Dox is loaded onto TPGS containing NPs. Conclusion: This magnetic PLGA nanoparticle system is important for new generation targeted chemotherapy and could be used for breast cancer treatment after in vivo tests.

Inhibitors of WEE1 and ATR kinases are considered promising for cancer treatment, either as monotherapy or in combination with chemo- or radiotherapy. Here, we addressed whether simultaneous inhibition of WEE1 and ATR might be advantageous. Effects of the WEE1 inhibitor MK1775 and ATR inhibitor VE822 were investigated in U2OS osteosarcoma cells and in four lung cancer cell lines, H460, A549, H1975, and SW900, with different sensitivities to the WEE1 inhibitor. Despite the differences in cytotoxic effects, the WEE1 inhibitor reduced the inhibitory phosphorylation of CDK, leading to increased CDK activity accompanied by ATR activation in all cell lines. However, combining ATR inhibition with WEE1 inhibition could not fully compensate for cell resistance to the WEE1 inhibitor and reduced cell viability to a variable extent. The decreased cell viability upon the combined treatment correlated with a synergistic induction of DNA damage in S-phase in U2OS cells but not in the lung cancer cells. Moreover, less synergy was found between ATR and WEE1 inhibitors upon co-treatment with radiation, suggesting that single inhibitors may be preferable together with radiotherapy. Altogether, our results support that combining WEE1 and ATR inhibitors may be beneficial for cancer treatment in some cases, but also highlight that the effects vary between cancer cell lines.

Cox 2

Major advances in cancer control can be greatly aided by early diagnosis and effective treatment in its pre-invasive state. Lung cancer (small cell and non-small cell) is a leading cause of cancer-related deaths among both men and women around the world. A lot of research attention has been directed toward diagnosing and treating lung cancer. A common method of lung cancer treatment is based on COX-2 (cyclooxygenase-2) inhibitors. This is because COX-2 is commonly overexpressed in lung cancer and also the abundance of its enzymatic product prostaglandin E2 (PGE2). Instead of using traditional COX-2 inhibitors to treat lung cancer, here, we introduce a new anti-cancer strategy recently developed for lung cancer treatment. It adopts more abundant omega-6 (ω-6) fatty acids such as dihomo-γ-linolenic acid (DGLA) in the daily diet and the commonly high levels of COX-2 expressed in lung cancer to promote the formation of 8-hydroxyoctanoic acid (8-HOA) through a new delta-5-desaturase (D5Di) inhibitor. The D5Di does not only limit the metabolic product, PGE2, but also promote the COX-2 catalyzed DGLA peroxidation to form 8-HOA, a novel anti-cancer free radical byproduct. Therefore, the measurement of the PGE2 and 8-HOA levels in cancer cells can be an effective method to treat lung cancer by providing in-time guidance. In this paper, we mainly report on a novel sensor, which is based on a newly developed functionalized nanomaterial, 2-dimensional nanosheets, or Ti3C2 MXene. The preliminary results have proven to sensitively, selectively, precisely, and effectively detect PGE2 and 8-HOA in A549 lung cancer cells. The capability of the sensor to detect trace level 8-HOA in A549 has been verified in comparison with the traditional gas chromatography–mass spectrometry (GC–MS) method. The sensing principle could be due to the unique structure and material property of Ti3C2 MXene: a multilayered structure and extremely large surface area, metallic conductivity, and ease and versatility in surface modification. All these make the Ti3C2 MXene-based sensor selectively adsorb 8-HOA molecules through effective charge transfer and lead to a measurable change in the conductivity of the material with a high signal-to-noise ratio and excellent sensitivity.
