In contrast to extracellular signals, the mechanisms utilized to transduce nuclear apoptotic signals are not well understood. Characterizing these mechanisms is important for predicting how tumors will respond to genotoxic radiation or chemotherapy. The retinoblastoma (Rb) tumor suppressor protein can regulate apoptosis triggered by DNA damage through an unknown mechanism. The nuclear death domain-containing protein p84N5 can induce apoptosis that is inhibited by association with Rb. The pattern of caspase and NF-kappaB activation during p84N5-induced apoptosis is similar to p53-independent cellular responses to DNA damage. One hallmark of this response is the activation of a G(2)/M cell cycle checkpoint. In this report, we characterize the effects of p84N5 on the cell cycle. Expression of p84N5 induces changes in cell cycle distribution and kinetics that are consistent with the activation of a G(2)/M cell cycle checkpoint. Like the radiation-induced checkpoint, caffeine blocks p84N5-induced G(2)/M arrest but not subsequent apoptotic cell death. The p84N5-induced checkpoint is functional in ataxia telangiectasia-mutated kinase-deficient cells. We conclude that p84N5 induces an ataxia telangiectasia-mutated kinase (ATM)-independent, caffeine-sensitive G(2)/M cell cycle arrest prior to the onset of apoptosis. This conclusion is consistent with the hypotheses that p84N5 functions in an Rb-regulated cellular response that is similar to that triggered by DNA damage.

Actions of reactive oxygen species on AH/type 2 myenteric neurons in guinea pig distal colon.

With conventional intracellular recording methods, we investigated the mechanism of actions of reactive oxygen species (ROS) derived from hypoxanthine and xanthine oxidase (HX/XO) reactions on AH/type 2 myenteric neurons in the guinea pig distal colon. Of the 54 neurons to which HX/XO was applied, 32 neurons showed a transient membrane hyperpolarization(s) followed by a long-lasting membrane depolarization. Two additional groups of 10 myenteric neurons exhibited only a membrane hyperpolarization(s) or a late-onset membrane depolarization, respectively, and the remaining two neurons did not show any response to HX/XO. Analysis of changes of the input resistance induced by HX/XO indicated that suppression and augmentation of the conductance of Ca(2+)-dependent K(+) channels are the ionic mechanisms underlying the membrane hyperpolarization and depolarization, respectively. The effects of HX/XO on myenteric neurons were mimicked by application of caffeine or H(2)O(2). The results suggest that OH(.), but neither H(2)O(2) nor O(2)(.-), is responsible for HX/XO-induced responses. The intracellular Ca(2+) store may be the acting site of ROS in colonic AH/type 2 neurons.

The hypothesis that the release of Ca(2+) from ryanodine receptor activated Ca(2+) stores in vivo can affect the function of the cochlea was tested by examining the effects of caffeine (1-10 mM) and ryanodine (1-333 microM), two drugs that release Ca(2+) from these intracellular stores. The drugs were infused into the perilymph compartment of the guinea pig cochlea while sound (10 kHz) evoked cochlear potentials and distortion product otoacoustic emissions (DPOAEs; 2f(1)-f(2)=8 kHz, f(2)=12 kHz) were monitored. Caffeine significantly suppressed the compound action potential of the auditory nerve (CAP) at low intensity (56 dB SPL; 3.3 and 10 mM) and high intensity (92 dB SPL; 10 mM), increased N1 latency at high and low intensity (3 and 10 mM) and suppressed low intensity summating potential (SP; 10 mM) without an effect on high intensity SP. Ryanodine significantly suppressed the CAP at low intensity (100 and 333 microM) and at high intensity (333 microM), increased N1 latency at low intensity (33, 100 and 333 microM) and at high intensity (333 microM) and suppressed low intensity SP (100 and 333 microM) and increased high intensity SP (333 microM). The cochlear microphonic (CM) evoked by 10 kHz tone bursts was not affected by caffeine at high or low intensity, and ryanodine had no effect on it at low intensity but decreased it at high intensity (10, 33, 100 and 333 microM). In contrast, caffeine (10 mM) and ryanodine (33 and 100 microM) significantly increased CM evoked by l kHz tone bursts and recorded from the round window. Caffeine (10 mM) and ryanodine (100 microM) reversibly suppressed the cubic DPOAEs evoked by low intensity primaries. Overall, low intensity evoked responses were more sensitive and were suppressed to a greater extent by both drugs. This is consistent with the hypothesis that release of Ca(2+) from ryanodine receptor Ca(2+) stores, possibly in outer hair cells and supporting cells, affects the function of the cochlear amplifier.

Sudden, and premature hair loss and
baldness is a problem in many ways.
Baldness is indeed becoming an increasing concern in the current aging society.
It changes personal appearance and identity in social context.
Saw palmetto berry extract is a widely known
herbfor hair loss as well as BPH problems in Western world.
Saw palmetto berry contains phytochemicals that inhibits 5-alpha-reductase that converts
testosterone to DHT.
There are a number of traditional herbs that could stop hair loss
and promotes hair growth.
Numerous personal experiences and anecdotal cases testify that the herbal formula based on the Chinese
herbs improves the situation of the age-related hair thinning and hair loss for a large fraction of people
taking it regularly. It is unknown how Hair Million herbs stop hair loss, and promote hair growth due to
the lack of scientific research and placebo controlled clinical trials.
