radiosensitivity

 [ra″de-o-sen″sĭ-tiv´ĭ-te]
sensitivity of the skin, tumor tissue, or other tissue to radiant energy, such as x-ray or other radiations. adj., adj radiosen´sitive.

ra·di·o·sen·si·tiv·i·ty

(rā'dē-ō-sen'si-tiv'i-tē),
The condition of being readily affected by radiant energy.

radiosensitivity

The relative susceptibility of cells and tissues to irreversible damage by RT, which prevents mitosis or completion of normal metabolism; lymphoid, hematopoietic, and gonadal tissues are most susceptible to radiation damage; some CAs–eg, lymphoproliferative, gonadal malignancies–eg, seminoma and small cell carcinoma of lung 'melt away' with RT. Cf Radioresistance.

ra·di·o·sen·si·tiv·i·ty

(rā'dē-ō-sen'si-tiv'i-tē)
The condition of being readily affected by radiant energy.

ra·di·o·sen·si·tiv·i·ty

(rā'dē-ō-sen'si-tiv'i-tē)

innoxia species alkaloids and with regard to its positive radiosensitivity response we performed an analysis of major alkaloids (atropine and scopolamine) by means of GC on both irradiated and control seeds.
Although absorbed dose describes the amount of energy absorbed in a 3-D volume, it does not take into account which organs or tissues absorbed the dose, their relative radiosensitivity or the risk of detrimental effects to those organs.
Additionally, low Ku70 expression in tumors with this genotype may indicate less effective DSBs repair, and thus, radiosensitivity, which could be in agreement with the experimental study showing the connection between inactivation of Ku70 protein and hypersensitivity to infrared radiation (IR) (22).
Our previous studies found that miR-21 could modulate the radiosensitivity of cervical cancer cells through targeting LATS1 [9], while miR-375 could regulate the sensitivity by targeting UBE3A [10].
The radiosensitivity index (RSI) developed by Torres-Roca and colleagues uses a systems biology approach and fraction of cells surviving 2 Gy (SF2) to define a clinically validated molecular signature that estimates radiosensitivity of multiple tumor types, including breast cancer [54].

In addition tissue of origin has been associated with radiosensitivity. For example, the SF2 (survival fraction of cells after 2 Gy of radiation) of melanoma and glioma cell lines has been shown to be higher (radioresistant) than lymphoma and myeloma cell lines [7-9].
Therefore, development of an effective radiosensitizer to enhance the radiosensitivity of hepatoma cells will play an important role in the treatment of HCC.
(9) It is speculated that defects in DNA repair mechanisms seen in these patients may increase radiosensitivity and susceptibility to carcinogenesis in the surviving cells.
