研究 の 目的:
- 食事によるマクロ栄養素摂取量と乳がんリスクとの関連性を評価する.
- 乳がんの発症における特定の脂肪 (不飽和,飽和) と炭水化物 (粉) の役割を調査する.
- 乳がん予防に役立つ食事パターンに関する洞察を提供するため.
主な方法:
- 2569人の乳がん患者と2588人の対照群を対象としたケース・コントロール研究.
- 1991年から1994年の間にイタリアの6つの地域で実施されたインタビュー.
- 検証された食品頻度アンケートでは,個々の脂肪パターンを含む食事による摂取量を評価した.
主要な成果:
- 脂肪の総摂取量の増加は乳がんリスクの減少と相関していた (傾向p=0.01).
- 利用可能な炭水化物の摂取量,特に粉の摂取量の増加は,リスクの増加と関連していた (傾向p=0.002).
- ポリ不飽和脂肪酸と不飽和脂肪酸を多く摂取すると,保護効果が示された (ORs 0.70と0.74).
結論:
- 不飽和脂肪酸は乳がんを予防する効果があるようで,野菜の摂取量が高いことと関連している可能性がある.
- 粉が豊富な食生活は,特に南ヨーロッパの集団において,乳がんのリスクをもたらす可能性があります.
- 研究結果は,特定の食事の変更が乳がんのリスクに影響を及ぼす可能性があることを示唆しています.

mTOR Signaling and Cancer Progression
The mammalian target of rapamycin or mTOR protein was discovered in 1994 due to its direct interaction with rapamycin. The protein gets its name from a yeast homolog called TOR. The mTOR protein complex in mammalian cells plays a major role in balancing anabolic processes such as the synthesis of proteins, lipids, and nucleotides and catabolic processes, such as autophagy in response to environmental cues, such as availability of nutrients and growth factors.

Cancer Prevention
Several factors can increase the risk of cancer in an individual. About 50% of cancer cases can be prevented by adopting a healthy lifestyle, regular exercise, eating healthy, and following a modest cancer prevention diet. Epidemiological studies have consistently shown that populations with vegetable and fruit-rich diets have reduced the incidence of cancer. On the other hand, populations who have a diet rich in animal fat, red meat, junk food, or high calories are predisposed to cancer.

Regulation of Food Intake
Short-term regulation of food intake primarily involves neural signals from the gastrointestinal (GI) tract, blood nutrient levels, and GI tract hormones. Communication between the gut and brain via vagal nerve fibers plays a significant role in evaluating the contents of the gut. Clinical studies have shown that protein ingestion produces a more prolonged response in these nerve fibers compared to an equivalent amount of glucose. Additionally, the activation of stretch receptors caused by GI...
Cancer Survival Analysis
Cancer survival analysis focuses on quantifying and interpreting the time from a key starting point, such as diagnosis or the initiation of treatment, to a specific endpoint, such as remission or death. This analysis provides critical insights into treatment effectiveness and factors that influence patient outcomes, helping to shape clinical decisions and guide prognostic evaluations. A cornerstone of oncology research, survival analysis tackles the challenges of skewed, non-normally...
