The selective estrogen receptor modulators (SERMs) are compounds that activate the estrogen receptors with different estrogenic and antiestrogenic tissue-specific effects. The similar effects of SERMs on estrogen encourage the efforts in the research of neuroprotective effects of SERMs. In our study, the potential neuroprotective effects of raloxifene were investigated on the brain cortex of ovariectomized rats after kainic acid-induced oxidative stress. To show the neuroprotective effect of raloxifene against a neurodegenerative agent, kainic acid, expression of Bcl-2, total glutathione (GSH), and nitrite-nitrate levels were investigated in the rat brain cortex. Our results demostrate that raloxifene treatment against oxidative stress significantly increases the expression of Bcl-2 and the level of GSH in the brain cortex.

Cytoplasmic proliferating cell nuclear antigen (PCNA) is highly expressed in acute myeloid leukemia (AML) cells, supporting oxidative metabolism and leukemia stem cell (LSC) growth. We report on AOH1996 (AOH), an oral compound targeting cancer-associated PCNA, which shows significant antileukemic activity. AOH inhibited growth in AML cell lines and primary CD34 + CD38 - blasts (LSC-enriched) in vitro while sparing normal hematopoietic stem cells (HSCs).

Background: A precise observation is that the cervix's solid tumors possess hypoxic regions where the oxygen concentration drops below 1.5%. Hypoxia negatively impacts the host's immune system and significantly diminishes the effectiveness of several treatments, including radiotherapy and chemotherapy.

Background: breast cancer-associated fibroblast (CAF) is linked to metastasis and is poor for breast cancer prognosis. Since Clostridium Toxin A (Botox-A) had represented a cytotoxic effect on fibroblasts, this study aims to assess Botox-A cytotoxicity in both normal fibroblasts and exosome-induced CAFs.
Material And Method: the serum exosomes of 40 BC patients and 30 healthy individuals were isolated and lncRNA H19 (lnch19) levels were assessed by qRT-PCR method.
